Edwards Signaling 171 GuardSwitch Series Exposion Proof Non-Contact Interlock/Position Switches

Sentrol Industrial 171 is an interlock/position switch ideal for explosive environments where combustibles are being used such as grain elevators and painting booths. The Sentrol switch enclosure is UL classified for: Class I, Group B,C,D; Class II, Group E,F,G; Class III, Divisions 1 & 2. Proximity of ferrous materials usually reduces sense range - typically by 50%. The shape and type of material cause a wide diversity of effects. Testing is required to determine actual sense range for specific applications.
