Safety switches take controllers onboard
Magnetic-coded noncontact switches for interlocking machine guard doors feature built-in controllers, saving both the cost and space required for a dedicated controller.
Omron's F3S-TGR-N magnetic coded noncontact switches are specially designed to interlock hinged, sliding or removable guard doors on all types of industrial machinery Compared with existing solutions, the F3S-TGR-N does not need a dedicated controller to monitor the proper functioning of the switches because this unit is already an integral part of the switch

Distribution boxes simplify field connections
Multiport distribution boxes simplify the applied wiring of sensor actuators, enabling multiple connections in an area with just one connection going back to the controller.
Snap mounting eases sensor installation
The novel mounting system used with E3FZ sensors completely eliminates the need for nuts and screws.
This is a huge benefit to machine builders because it reduces the number of control units required in the instrumentation or control cabinet.
The F3S-TGR-N noncontact switch range also benefits from the generation of no particles often created by switches as they make contact with a door frame.
The noncontact switch also remains relatively unaffected by wear and tear which often causes normal contact switches to need re-adjustment after a short time.
It is also easy to calibrate for a range of mechanical tolerances and features an LED for easy visual diagnosis.
Conforming to EN954-1 (up to safety category 4) and EN60947-5-3 (PDF-M), the switches are available in plastic or stainless steel housings.
The latter type of housing is a special requirement in the food packaging and pharmaceutical industries where cleaning using aggressive detergents is necessary to meet hygiene requirements.
In these environments switches are frequently placed behind machine covers to protect against the effects of cleaning.
The F3S-TGR-N is well suited for use in these applications because its use of noncontact technology makes it possible to house the unit inside a stainless steel cover without affecting the performance of the unit.
A further benefit of the F3S-TGR-N is that it offers machine builders greater flexibility regarding the safety control system they install for their machines.
For instance, if the safety system has to cover different machines, the same switches can be used together with safety relay units such as Omron's G9SB for small machines, and DeviceNet can be used for bigger installations. Request a free brochure from Omron Electronics ...
