Omron D40A-1C5 Safety Door Switch
Omron D40A-1C5 is a 5 m cable non-contact safety door switch designed for protective-door and machine-guard position monitoring without mechanical switch actuation. Its integrated 5 m cable provides additional connection length for installation around guarded machinery, while the specified operating-distance variation is 20% or less at 23°C, with a maximum distance of 2.5 mm. The non-contact sensing arrangement supports protective access monitoring without conventional tongue-operated switching. The D40A-1C5 belongs to the D40A Series within the non-contact machine safety switch range from Omron industrial safety products, connecting machine guard position, protective access detection and compatible safety control systems.

The Omron D40A-1C5 Non-contact Safety Door Switch provides machine guard and protective-door position detection without requiring conventional mechanical switch actuation. Its non-contact sensing arrangement establishes the relationship between the switch, actuator and guarded access point, allowing door position to be monitored by a compatible safety control system. The integrated 5 m cable provides additional connection length for installation around industrial machinery. Its specified operating-distance variation is 20% or less at 23°C, with a maximum operating distance of 2.5 mm. The main semantic relationships are non-contact safety switching, protective-door detection, machine guard monitoring, actuator position and safety controller integration. These functional entities provide stronger product context than secondary weight, vibration or resistance values. The D40A sensing principle also distinguishes this series from conventional tongue-operated mechanical safety door switches because guard detection does not depend on physical switch actuation. Cable length becomes a useful model-selection attribute when choosing between otherwise related D40A variants. The D40A-1C5 therefore links a monitored protective access point with the connected machine safety architecture through non-contact detection. For the same D40A safety door function with a shorter integrated cable, the D40A-1C2 provides the closest related model.
