The D40Z-1C2 is an induction-type door switch with a 2-meter cable, used to detect door position in industrial enclosures and safety gates. The induction sensing principle means it detects metal targets through non-ferrous barriers — useful where a mechanical plunger would wear or where the door material is aluminum or stainless steel.
The 2-meter cable is the key fit parameter — it determines how far the switch can be from the control cabinet or junction box. Plan for cable routing and strain relief; the cable is permanently attached, so replacement means swapping the whole switch, not just the head. Induction sensing is immune to dust and light contamination, making it suitable for washdown or outdoor enclosures where optical sensors would false-trigger.
