The D4BS15FS is a safety-door switch designed to enhance production site safety by directly pulling contacts apart when an operation key is used. It features a 1NC/1NO slow-action contact configuration where the NC contact has an EN-approved direct opening mechanism for forced disconnection. Housed in an IP67-rated enclosure with a single PG13.5 conduit, it ensures robust protection against dust and water. The switch is rated for AC-15 at 2A/400V (TÜV) and A600 (UL/CSA), and operates reliably across a wide temperature range of -40°C to 80°C. Conforming to multiple international safety standards, it is ideal for machinery safety systems, protective doors, and access panels on industrial equipment.
