SMC D-M9-551/918 Solid State Auto Switch (UL/CSA Certified)

SMC D-M9 solid state auto switch in UL/CSA certified versions (-551) and UL/CSA certified with secondary-battery material restrictions (-918).

Key features

UL/CSA certification identified by suffix -551; -918 adds material restrictions for secondary (lithium-ion) battery production lines
Identification marking printed on the switch body and an identification label on the lead wire
2-wire, 3-wire NPN and 3-wire PNP outputs; in-line or perpendicular (V) lead wire exit; 1-color indicator
Lead wire / connector symbol: none 0.5 m, L 3 m, SAPC M8 3-pin 0.5 m, SDPC M12 4-pin 0.5 m (inserted before the certification suffix)
Dimensions and specifications are common with the general-purpose D-M9 type
Supplied as a switch alone; cannot be ordered or shipped together with an actuator model number
