The HS1L-DT44KMSRM-R is a solenoid-operated interlock switch with spring lock mechanism designed for monitoring door open/closed and lock status in industrial safety applications. It features a 24V DC rated operating voltage with 200 mA initial current draw and 120O coil resistance at 20°C, delivering 3000N minimum locking strength suitable for large and heavy doors. The device includes six contacts in a compact 35 × 104 × 129 mm housing with DT circuit configuration (1NC/1NO main circuit, 2NC monitor circuit), manual unlock key, and independent LED indicator circuit (24V DC, 10 mA rated current). Operating across -20°C to +55°C with IP67 degree of protection and 1,000,000 mechanical operations minimum durability, it meets ISO14119, IEC60947-5-1, UL508, and GS-ET-19 standards. This interlock switch is ideal for access control, machinery guarding, and safety interlocking systems requiring reliable door monitoring and emergency manual unlock capability.
