The HS5D-02RN is a basic safety interlock switch with a plastic head designed for machine safety applications. It features 2NC (two normally closed) main contacts and a G1/2 conduit port size, with a compact form factor that allows up to three contacts. The switch incorporates head detachment detection for enhanced safety, a retention force of 50 N, and achieves a B10d cycle rating of 2.0E+06 cycles. This interlock switch is commonly used in machinery guarding systems, access control, and safety interlocking applications where reliable contact switching and head position verification are critical for operator protection.
