The SICK SFS60-HMKT0S01 is a coded-magnetic safety interlock switch designed for guarding doors, flaps, and access points on industrial machinery. It uses a unique coded magnetic actuation principle to prevent tampering or bypassing (e.g., with magnets). When the door opens, the switch immediately cuts power to hazardous motions via its safety outputs (OSSDs), ensuring compliance with safety standards (ISO 13849-1 PL e, IEC 61508 SIL 3). Its compact metal housing, high IP rating, and flexible mounting make it ideal for harsh environments like robotics, presses, and automated production lines.
