Schmersal ZQ900 Rugged Emergency Pull Wire Switches

The Schmersal ZQ900 series rugged safety pull wire switches offer emergency stop solutions for use along the length of conveyors or similar types of installations.

The die-cast body of the switch provides protection from harsh environmental conditions and an external watertight collar provides IP65 ingress protection, making it suitable for use in applications ranging from mining conveyors to packaging systems. Up to 75 m can be covered by one single switch when using a tensioning spring, and LED indication is optional for status indication in installations of more than one device.

Integrated safety features include an emergency stop button on the front housing of the switch, offering full emergency stop functionality across the entire protected area. Wire pull and breakage detection ensures the system remains operational at all times.

Installation is made easier by the addition of 3x M20 cable entries on both sides and at the back of the switch body and setting the tension is aided by a transparent indication window on the front of the housing.
