For use in: Class I - Groups A, B, C, & D CONTROL MODULES Class II - Groups E, F, & G The EE931 Hazardous Location BARRIER sensor system is excellent for sensing of position in paint spray booths, belt slip on conveyors, or anywhere that explosion proof switches are normally used. Since Hazardous the EE931 system is intrinsically safe, no special housings are required to contain any potential flame. Intrinsic Safety is obtained by design of the product such that extremely limited energy is available Hazardous in the hazardous location. For this reason, these Namco sensors must only be used with the Namco control module. It is possible, however, to use the Namco control module with either the Namco
sensors listed in this section or a Hazardous

An intrinsically safe proximity sensor system consists of a sensor, which is mounted in the hazardous area, and a control module, which is mounted in the safe area.
