Summary
This article introduces the D40A-2 non-contact security door switch launched by Omron, which supports series connection of up to 30 switches with a maximum distance of 200 meters while still achieving the highest security level (PL e / Cat. 4). The product adopts RFID high encoding technology, has excellent anti-tampering capabilities, is suitable for multi-door control scenarios, and helps manufacturers achieve efficient and secure access control management in a more simplified way.
OMRON launches D40A-2 non-contact safety door switch.When the inspection door is opened, the non-contact safety door switch can stop the equipment in time, which is crucial to ensuring the safety of workers and preventing accidents during equipment operation.
Features of D40A-2 Non-contact Safety Door Switch
✅Small actuators – Actuators that are smaller than switches can save space, even inside doors.
✅Can be mounted on either side - this provides the easiest wiring path and can be mounted on all door types.
✅Its versatile design is suitable for revolving and sliding doors, and its application range covers single-wafer cleaning machines, filling machines and robotic manufacturing.
✅Even when connected in series, the D40A-2 meets the highest safety level requirements (PL e / Cat. 4) and supports up to 30 switches in an application range of up to 200 meters. This feature enables manufacturers to efficiently manage multiple access points through one security controller, achieving a simpler security system architecture.
✅The D40A-2 has powerful diagnostic features, includes an auxiliary output for relay operation, and supports multiple configurations (PNP or bipolar NPN/PNP)
✅Easy-to-See Dual-Color Indicator - Red/yellow LED indicators allow for easy at-a-glance status of switches.
