Choose from 2-wire sensors with AC/DC operation, or 4-wire sensors Product Features in either AC or DC styles. Connection options include terminal, mini- Rugged construction is ideal for industrial environments connector or various lengths of cable. Viton gaskets ensure a positive seal and high resistance to industry chemicals Choose from standard sensors that detect all types of metallic targets. Direct replacement for worn out limit switches The next page provides more detail Sensor heads and bodies feature captive screws to eliminate loss on these sensors. All sensor heads include a selector switch to program output function to either N.O. or N.C. Approvals Sensor bodies feature bifurcated engagement prongs for a reliable UL Listed connection when plugging into receptacle stabs CSA Certied Engagement key between sensor body and receptacle prevents improper assembly (where shown) Sensors accommodate both U.S. and DIN mounting dimensions Wiring terminals feature captive pressure plate saddles for 18 to 12 AWG wire. A green screw identied ground terminal is also included Unless otherwise noted, the products contained in this Logic modules are available to provide additional control functions document are not designed or intended for use in human safety applications.
