| The industry's most complete line of contact and non-contact products. GE Security Industrial safety interlock switches are used to detect the opening of guards-including doors, gates and/or removable covers-that prevent access to dangerous parts of a machine, and to help deter tampering with the guards or the internal machine controls. As with all GE Security Industrial 300-BT products, the safety interlock switches are in full compliance with the most current and required standards. These include IMQ, CE, VDE, UL, CSA, IEC, EN and Semi S2 standards. |

The magneto resistive sensors detect the movement of ferromagnetic materials, by means of the change of the magnetic flow. They are available with (Series 350) or without (series 300) detection of direction of rotation.
They are suitable for rotary speed sensing, for detection of gearwheels and for standstill control. Areas of use can be heavy construction engines, rail vehicles, large diesel engines and -turbines. Rotary speed sensing is possible with gear wheels form module 1, with a max. switching frequency of 15 kHz. |

The Swiss sensor manufacturer Contrinex, specialized in long operating distance and miniature devices, now offers a large selection of the world's smallest, fully self-contained inductive and photoelectric proximity switches.
With housing diameters of just 3 mm up to M5, plus cuboid 5 x 5 x 25 mm formats, the sensors have electrical characteristics equivalent to larger types. In addition, they also contain all the usual built-in protection functions, such as short-circuit, voltage-reversal and overload protection, and feature high levels of EMC.
Despite their small dimensions, the inductive models offer operating distances of 0.6 to 1.5 mm. Mechanically robust, with stainless-steel housings and full potting, these devices are highly suitable for rugged applications.
The photoelectric models are available with housing diameters of 4 mm and M5, as diffuse and through-beam executions, and have operating distances from 10 to 250 mm.
These tiny sensors are ideally suited for applications where space is limited. They require no separate amplifiers, and are thus easier to install and considerably cheaper than equivalent fibre-optic solutions. |

Honeywell's miniature position sensors respond to the presence or the interruption of a magnetic field by producing either a digital or an analog output proportional to the magnetic field strength. These Hall-effect sensors have single and double sensing elements for mounting on IC chips. These extremely small sensors come in a variety of magnetic actuation types including omnipolar, unipolar, bipolar, bipolar latch, ratiometric and analog. Termination types include radial lead IC and surface mount. Some products are available on tape and reel.

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, safety 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 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 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. |

| Our huge standard programme with its diversity of housings has the optimal solution for almost any application. The various types of clamp or the dovetail connections directly integrated into the switch mean that the switches can be fitted on almost any type of cylinder. Our range also includes pneumatic 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. |

| Position and movement detection is indispensable in the automation industry. Non-contact proximity switches allow for a significantly higher number of switch operations than mechanically operated switching elements. The different elobau variants usually use reed technology and are operated with magnets. Steel proximity switches and vane switches are the exception as they are operated by a ferrous metal. |
