PRAS1: Contact-Free 360° Angle Sensor in Ultra-Compact M-12 Housing
ASM GmbH sets the new benchmark for angular position detectors with the new development of a magnetic angle sensor in a very compact M12 housing. The PRAS1 sensor provides absolute position measurement over full 360° sensing range and is part of the successful POSIROT® family of magnetic angular sensors. With only a 1/2 inch diameter and overall length of less than 2 inches, this small sensor saves space and can be installed in the tightest locations.
The contact-free and wear-free angular measurement of 0° to 360° is achieved by using a position magnet. PRAS1 has a typical resolution of 0.1° and yields an analog signal through the use of a D/A professional converter. Three different analog outputs are available: 4-20 mA, 0.5-4.5 V and 0.5-10V. The industrial housing is rated up to IP68.
With its dependable and rugged design, the PRAS1 angle sensor is well suited for angle monitoring in a wide variety of heavy duty applications such as factory automation equipment, variable cock controls, mobile working machines, etc.

| The QR angle sensor is designed to measure non contact rotary displacement from 0 to 360 degrees without mechanical stop. A magnet needs to be fitted to the rotating axle and the sensor can be mounted opposite with a maximum 5 mm gap. This gives plenty of room for mechanical tolerances in extreme circumstances. In combination with our robust QUADRO® (PDF) housing you get a accurate sensor that withstands a few knocks. We supply a range of electronic input / output options with 8, 10 or 12-bits resolution to cater for the wide range of applications. Custom design housing with or without integrated magnet are an option. |

| The Schaevitz® line of rotary position transducers offers high reliability for absolute rotary position measurements in a range of specialized applications. Standard features include a non-contacting design, 120 degree measuring range, 360 degree free rotation, virtually infinite rotational life, infinite resolution, a wide operating temperature range and a fully signal-conditioned output. Applications include industrial controls, cock position, robotics and throttle controls. |

The compact DFP-2 is perfect for use in use in dancer control applications with the MAGPOWR VERSATEC™, and in dancer and follower arm applications with the DFC-90 and FAD. It offers the same exceptional sensing performance as the original DFP sensor, but in a lighter duty low cost housing.
And what's already included in the DFP-2 is a servo type spider coupling to allow for misalignment in shaft-to-shaft applications as well as fifteen feet of shield cabling for ease of installation. |

The combination of a coder with ends of the road in the same case increases the reliability and the safety of the machines, because of two independent checking circuits in the same case.
The coder integrated provided information uninterrupted of the movement in 5-30 VDC with a resolution from 100 to 5000 increments. The programmable ends of the road, the catch of origin are regulated freely with the position wished.
The adjustment of the ends of the road is very simple: the case is assembled on the machine, the machine is then led manually to its limiting position, the end of the road is positioned with a key of programming. This procedure is repeated for the other end of the road.
The case is well protects by its cap against dust or any external intervention; all the signals are cabled on a manufacturers of connector with the back of the case.
These cases can also be provided with potentiometric.
COMP' AUT will be able to best advise the customer in the choice of the case being appropriate for its application.

No One Protects Large Turbines like GE
The transducers in this category measure changes in machine case positions as they expand or contract, rotary or linear position of control valves suppliers, or wicket gate position on hydroelectric turbines. They are typically used in conjunction with other transducers as part of a Turbine Supervisory Instrumentation (TSI) package, designed to monitor all critical machinery parameters on large steam, gas, or hydraulic turbines used in power generation applications.
The 3300 XL Rotary Position transducer (RPT)
This innovative transducer incorporates a proximity probe observing an eccentric cam. The changing gap between probe tip and cam corresponds to degrees of rotation, and is specifically designed for cock position measurements. It is a superior alternative to older potentiometer transducers which have poor reliability. |

Position switches for high temperature
For more than 20 years Pizzato Elettrica has been producing one of the world most wide range of position switches, protection switches, microswitches, foot switches. Pizzato Elettrica products are usually used worldwide in different industrial sectors characterized by their reliability and their quality/price ratio.
Eventually the range of products in the survey sector has been growing covering very specialized sectors such as switches in conformity with ATEX directive and switches with electronic contacts.
Among the various new products 2007 Pizzato Elettrica has introduced a new series of position switches especially studied for high temperature application. These products are characterized by their long mechanical life in relation to the working temperature, that is up to 1 million operation cycles at +180°C.
A dedicated brochure on these new products is available on the website www.pizzato.com. |

Position switches are used wherever moving parts on machinery and plants need to be positioned, controlled and monitored.
The design details in relation to body dimensions, materials, electrical loading capacity, rated values and quality characteristics are to a great extent determined by the variety of application, from precision mechanics to heavy engineering.
Many of the position switches fulfill the requirements of the IEC 60947-5-1 product standard and can therefore also be used as position switches with safety function.
The position switches are available with snap action or slow action.
A wide variety of manufacturers of actuator heads are available. The majority of units are also obtainable with metal rollers.
The position switches are shown in the sequence of body sizes, starting with the smallest design.
Schmersal make both standard and AS-i Safety at Work safety modules.

Position Sensing Solutions
Bimba offers pre-tested Position Sensing Solutions for Bimba industrial actuators. Our solutions provide a cost effective interface between the manufacturer of 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 suppliers. 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. |
|
| Our huge standard programme with its diversity of housings has the optimal solution for almost any application. The various types of workholding or the dovetail connections directly integrated into the switch mean that the switches can be fitted on almost any type of professional cylinder. Our range also includes compressed air cylinder switches for T-section cylinders. All the models can be supplied with dry reed contact with variable power capacities or in the electronic version. If you wish, we can develop completely new customer-specific sensors to meet your requirements. |
