However, they should not be placed in conduit with power wiring. Class 1 wiring is required. MOUNTING DIMENSIONS (For reference only) 18 mm mm in. Proximity 30 mm The 973EX Series is approved for hazardous locations. It may be made suitable for explosive atmospheres with the application of special explosion proof seal fittings and conduit as required by the National Electrical Code (NEC), Article 500. MICRO SWITCH does not supply these fittings and conduit. It is the responsibility of the purchaser or installer to supply the required material.
