Position switches are used to monitor the position of moving parts of machines and plant. Can be used in safety circuits, as the device satisfies EN 60947-5-1 / DIN VDE 0660 part 200, and the opening contacts are positive opening. The position switch with positive opening contacts has been tested to the professional association test standard GS-ET 15 of the German Employer Liability Insurance Association, and is thus licensed for personnel protection functions. Category 1 safety position switches have contact and actuating element in a single constructional and functional unit. Category 2 safety position switches do not have contact or separated functionally. As a result of galvanic isolation of the moving contacts, the position switch is suitable for switching various potentials.

Hall Effect Devices detect magnetic flux density (mainly produced by a permanent magnet) and are used in both movement and position sensing. By integrating the sensing element onto the same silicon as its control logic and interface circuitry, Melexis has produced sensor chips with various degrees of intelligence to suit most applications. Sensing the rotation of shafts (e.g. cam- and crank-shaft) in engine, monitoring movement in motors and actuators, sensing pedal, throttle and steering wheel position, Melexis Hall Devices offer a reliable, contactless method of movement and position detection.
Melexis is a technological leader for the design, development and testing of integrated Hall Effect Devices. Melexis Hall Effect Devices enable an optimal use of the smaller feature sizes of which semiconductor technology is capable today. Therefore, very sophisticated mixed analog-digital signal conditioning circuitry (such as Chopped Analog String, Digital Signal Processing Core, Microcontroller) can be integrated. Most of the devices can withstand the severe automotive conditions despite few external components.

Description:
These Hall-effect devices contain a monolithic integrated circuit which incorporates a Hall element, a linear amplifier, a threshold amplifier, and Schmitt trigger on a single Hallogic® silicon chip. Included on-chip is a band gap voltage regulator to allow operation with a wide range of supply voltages. These devices feature logic level output and provide up to 21 mA of sink current. This allows direct driving of more than 7 TTL loads or any standard logic family using power supplies ranging from 4.5 to 24 volts. Output amplitude is constant at switching frequencies from DC to over 200 kHz. The Uni-Polar turns on with a (logic level “0”) after a sufficient magnetic field from the south pole of a magnet approached the symbolized face of the device (Operating Point) and turns off (logic level “1”) after the magnetic field reached a minimum value. The Bi-Polar latch device turns on (logic level “0”) in the presence of a magnetic south pole and turn off (logic level “1”) when subjected to a magnetic north pole. Both magnetic poles are necessary for operation for Bi-Polar devices. This feature makes these sensors ideal for applications in noncontact switching operations, brushless DC motors and for use with multiple pole magnets.
Features:
- Designed for non-contact switching operations
- Operates over broad range of supply voltages (4.5 V to 24 V)
- Operates with excellent temperature stability in harsh environments
- Drive capability up to 7 TTL loads

All the electronic sensors work on a non-contacting basis using magnets - this includes Hall and magnetoresistive sensors. The exceptions are the gear-wheel sensors which use a ferrous gear-wheel. The advantage of magnetoresistive sensors is that the same sensor, a standard small model, can be used for different operational distances. The operational distances which can be achieved depend only on the strength of the magnet used. All the models can also be delivered with non-wearing Hall sensors. Besides the various standard models, we also manufacture customised housings to your requirements.

Non-contact magnetic sensor proximity switch produces a digital output. The output produced by Hall-Effect Proximity Switch sensor switches between logic low (operate point) and logic high (release point) with presence and absence of a magnet as a target. The difference between the magnetic operate and release points is called the hysteresis of the device. The built-in hysteresis circuitry allows clean switching of the output even in the presence of external mechanical vibration and electrical noise.

The RPS-400-6 is a compact, high frequency sensor. It was introduced to the Migatron family of ultrasonic sensors to better meet the needs of the machine manufacturing industry.
This sensor has a wide array of application solutions not found in other proximity sensor technologies. The RPS-400-6 has an adjustable two to six inch sensing range with background suppression (meaning any object within the desired range is detected, while objects out of the desired range are ignored).
It cannot be affected by changes in target color or material. The RPS-400-6 is capable of detecting vibrating and/or tilting targets. A response time of no more than 2.1 ms and an operating frequency of 300 kHz makes the RPS-400-6 a repeatable and accurate high speed sensor.
The RPS-400-6 is a three wire NPN transistor output device. The transistor can switch 30VDC at 50 mA continuously. A six-foot cable comes standard with the RPS-400-6. Special cable lengths or connectors are also available for OEM applications.

HIGH TEMPERATURE SENSORS
Significant scientific and engineering enhancements in advanced materials, Pre-Process and In-Process production methods and in-site testing methods are driving the demand for displacement sensors that can handle extremely high temperatures up to 1832°F (1000°C). Contemporary producers of aircraft engine rotational alignment, plate glass, materials testing extensometry, continuous flow steel, now use standardized high temperature Capacitec sensor solutions for in-process applications to control the quality of their production on a real time basis. Qualification testing of disc brakes, jet engine dynamics and high speed shaft rotations also rely on Capacitec sensors. Advanced materials for automobiles, structural components, and aircraft are also tested for strength and durability with the use of Capacitec's line of extensometers and clip gauges.
High Temperature Major Applications:
- Disc brake testing
- Silicon Wafer processing
- Metal and Glass forming
- Jet engine thermal expansion
- Material strength testing
- Mold separation
- Turbine testing
- Strain Extensometry

Capacitive sensors (KAS) react to metals and non-metals that exceed a specific capacitance on approaching the active surface. The sensing distance with respect to a specific material is greater the higher the dielectric constant. The sensors are used to detect objects, for counting functions and for all types of level monitoring applications in liquid materials (i.e. water, oil, acids, glue) and bulk materials (i.e. pouder, granulate, pellets).
|
|
|
Loop detectors are used wherever vehicles have to be detected. For example for monitoring and safeguarding accessways or for counting vehicles. The output signal can be used for controlling door and gate drive mechanism, operating barriers, controlling traffic light systems in car parks or activating card dispensers in car parks.

In industrial processes where liquids, air or gases are used valves serve for dosing and control. There is a wide variety of valve types, butterfly or ball valves being the most common quarter-turn types.
In large plants these valves are seldom operated manually. Mechanical actuation is normally done by separate actuators. The valve position must be monitored electronically. This is necessary to give feedback to the controller when a certain position (e.g. "open" or "closed") is reached and to monitor the valves centrally from a control room.
Mechanical switches are still often used for position feedback on the actuator shaft. For other solutions several proximity switches are used together with a switching target for position detection. Disadvantage of these solutions: Mounting is mechanically complex. During switch mounting the signal wires can be reversed when they are connected in the top-mounted junction box. Where there are temperature fluctuations condensing humidity leads to corrosion and thus malfunction.

Inductive Proximity Switches SIMATIC PXI
Instinctive Response to Metal
When identifying metal objects without contact, inductive proximity switches are simply the most cost-effective solution. If an electrically or magnetically conductive object approaches or leaves, they automatically send out a signal change. Inductive proximity switches are extremely reliable with a high repeat accuracy. And thanks to wear-free operation as well as resistance to temperature, noise, light or water, they have a markedly long service life. We cover the complete application spectrum with a large variety of designs and transmission ranges.

Inductive sensors (IAS) feature transistorised oscillators whose power consumption is influenced by the approach of metals and other electrically conductive materials such as carbon. Non-conductive metals can also achieve this effect.
These devices can be used as limit switches and position sensors for monitoring and positioning applica-tions in machines and installations as well as pulse generators for counter systems, distance measurements, speed control and many other applications

Inductive sensors
Inductive sensors use the interaction between metallic conductors and their electromagnetic alternating field. Eddy currents are induced in the conductor, which remove energy from the field and thus reduce the height of the oscillation amplitude.
This change is evaluated by the inductive sensor.
SensoPart offers a variety of inductive sensors with standard or enhanced working ranges.

In all automated processes the use of sensors to provide information for the plc is of prime importance. Sensors supply the necessary signals on positions, end stops, levels or serve as pulse transmitters for counting jobs or for monitoring rotational speed. In industrial usage inductive and capacitive proximity switches are indispensable. As compared to mechanical switches they offer almost ideal conditions: non-contact, maintenance-free operation, high switching frequencies and switching accuracies as well as high protection against vibration, dust and humidity.
Inductive sensors detect all metals without contact, capacitive sensors detect nearly all solid and liquid media such as metal, glass, wood, plastic, water, oil, etc...
Both inductive and capacitive proximity switches are available in NAMUR versions. In conjunction with an NV0100/NV0200 amplifier the sensors can be used in zone 1 hazardous areas (the amplifier which contains Zener barriers as well as power supply and output must be mounted outside the hazardous area).
