Omron
Non-contact safety door switch
Omron has added the 'D40A-2' to its range of non-contact safety door switches, which are essential for instantly stopping machinery the moment an access door opens.
The safety door switch uses Hall effect detection and coded magnetic actuators. Its versatile design fits both swinging and sliding doors, in applications ranging from single wafer cleaning systems and filling machines to robotic manufacturing. The switch offers compliance with PL e / Cat. 4 safety standards, even when connected in series. It also supports up to 30 switches in a single long-distance application up to 200 meters. This feature allows manufacturers to secure multiple access points with a single safety controller. According to Omron, the safety door switch has robust diagnostic capabilities and an auxiliary output for relay operation. It also supports multiple configurations (PNP or bipolar NPN/PNP). To meet the stringent hygiene and durability standards required by the food and beverage industry, the device has a label-free, direct laser-marked design. It comes with IP66/IP67 water-resistant protection rating and ECOLAB certified chemical resistance, ensuring resilience against water jets and harsh cleaning agents.
