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..

Position Sensing Solutions
Bimba offers pre-tested Position Sensing Solutions for Bimba actuators. Our solutions provide a cost effective interface between the pneumatic actuators and electrical control systems. Our pre-tested solutions also eliminate costly, time-consuming design and fabrication required if switches are purchased separately and provide an aesthetically pleasing installation.
Both traditional Bimba switches as well as newer generations of Bimba switches are offered to allow for maximum flexibility to fit your application.
The switches perform the same functions as conventional limit switches. They can be used as position indicators, cycle counters, or to confirm operation.
All Bimba switches are designed to sense a magnet that is incorporated into the piston of the cylinder. Magnets are standard in Bimba MRS cylinders, but must be purchased as an option on other Bimba actuators.
A variety of outputs are offered for each switch family including PNP (transistor sourcing), NPN (transistor sinking), normally open contacts, and higher power triac.

The new SMAT continuously detects the position of the cylinder piston within a range of 50 mm. It has an analogue output with an output signal in proportion to the piston position. The integrated OOR (out-of-range) sensor indicates if the piston is outside the sensing range. The connection for evaluating the 0 … 10 V and/or the 4 … 20 mA signal is made directly to analogue inputs.
Typical areas of application in object detection are as follows:
Press-fitting, clamping, position sensing, workpiece replacement
In process monitoring:
Sheet metal handling/production, wear monitoring, quality inspection
- The installation direction of the SMAT in the slot can be chosen freely.
- Contactless measuring principle = wear-free sensing.
- Measuring range is always 50 mm, regardless of cylinder; reproducibility 0.1 mm.

The RACO path-sensory system has been specially designed for exactly positioning and switching off electro-magnetic actuators in the final position. Not only is the position ascertained unconventionally by electro-magnetic means (e.g., gear-shifting mechanism) while doing so but it will also be determined via a close-coupled magnetic field without any movement.
The EPS consists of a printed circuit board and a magnetic holder with the magnet. The electronic positioning sensor (EPS) is integrated into the device%u2019s supplementary casing (A) on the motor shaft's end of the servo-motor or in the device's supplementary box (D) on the coupling casing. The installation, commissioning (starting up), maintenance (servicing) and upgrading is simplified in comparison with a conventional design that has mechanical limit switches and a shift transmission which must be adjusted individually.

Magnetic Reed Switches
Magnetic reed switches are available on nearly all air cylinders offered with Ultramation Linear Thrusters. Reed switches are actuated by the close proximity of a magnet which is included within the cylinder as part of the piston assembly. A reed switch contains a normally open sealed reed that closes or makes in the presence of a magnetic field. The reed switch returns to the normally open state once the magnetic field is removed. Reed switches, both with and without LED position indicators, are used in the vast majority of applications where the magnetic piston briefly comes to rest at each end of the stroke.

Application:
Safety switches with separate actuator are suitable for sliding, hinged and particularly removable safety guards, which need to be closed to ensure the necessary operational security. They are also suitable for fitting on profile sections and existing equipment.
In combination with safety control modules all safety switches with class 2 shown in this chapter achieve Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
On the safety switches with class 2, the switching element is not physically connected to the actuator but functionally brought together or separated for switching. When the guarding device is opened, the actuator is separated from the base unit. In the process, NC contacts are positively opened and NO contacts closed.
Enclosure rating of all the safety switches is IP 67. The safety switches can be fitted in any desired mounting position.
Schmersal make both standard and AS-i Safety at Work safety switches with separate actuator.

SAFETY SWITCH WITH SEPARATE ACTUATOR FW SERIES
These safety switches are ideal to control gates, sliding doors and other guards protecting dangerous parts of machine. The stainless steel actuator is fastened to the moving part of the guard, so it is removed from the switch on every opening of the guard. The switch mechanism guarantees that removing the actuator forces the positive opening of the electrical contacts. Easy to install, these switches can be applied to any kind of protection (with hinge, sliding and removable ones). Besides, the possibility to actuate the switch only with its actuator guarantees that the machine can be restarted only when the guard has been closed.

- Protection degree IP67
- 6 contact blocks available
- 8 stainless steel actuators available
- 30 N actuator extraction force versions
- Silver contacts gold plated versions

Bernstein presents the innovative safety switch SLK as a solution to safety applications in industrial automation. The SLK performs a slim and compact enclosure as well as a mounting acc. per EN 50041 standard. The outstanding feature is the availability of a multi-supply voltage version covering a range from 24 V DC up to 230 V AC. The new actuator head allows both, horizontal and vertical, actuation. Turning the actuator head by 4 x 90° makes it easy to fit the SLK safety switch to various movable guards. The SLK features two independent safety circuits which monitor the position of the movable guard and the condition of the interlocking. Both circuits carry combinations of up to two forced disconnected contacts each and thus achieve compatibility with different safety systems.

The UltraSensor has been designed as a next generation replacement of Proximity and Micro switch systems for monitoring spool movement in progressive divider elements.
A single model will work with all standard SMX and SMP divider blocks as a screw-on accessory without requiring special arrangement or modification to the spool.
The patented concept works by monitoring magnetic flux variations through a hall-effect sensor as the spool enters the sensing range. There are no moving parts which means the solid state device is completely wear free.
NPN and PNP connection options are standard within the same sensor.
