Safety Interlocks


Product Code: 101144260

The Schmersal AZM170 series solenoid interlock is a robust machine safety solution designed for power-to-unlock operation with a manual release feature. This device offers two actuating directions and includes one auxiliary contact as well as one safety contact, ensuring versatile integration into various safety systems. Equipped with screw terminals for secure connections, the interlock has both normally open (NO) and normally closed (NC) contacts to fit different circuit requirements. It can handle a thermal test current of 6 A and operates efficiently at a rated control voltage of 24 VAC/DC. The unit is rated for utilisation categories AC-15 at 230 VAC up to 4 A and DC-13 at 24 VDC up to 4 A, making it suitable for a wide range of applications in machine safety.
