Position switches with safety function
ZSM476E
- Thermoplastic enclosure
- Switching function latching
- Screw and pinch terminals for connection of wires
- Low actuation force and short contact trip value
- Magnetic trip action
Area of application
Position switches with safety function are suitable for a wide range of applications in lift industry. They are especially used, where safety and positioning accuracy are of paramount importance, e.g. at the terminus, at the safety catch device or at the speed limiter.
For these applications, Schmersal offers a comprehensive program of position switches, which have proven their value to the lift industry all over the world. The different series can be smoothly adapted to the specific application by means of a wide range of actuating elements.
All position switches with safety function have a positive link between the actuator and the positive break NC contact. The switches are available with two different switching systems: snap action (Z) and slow action (T). The protection class of all series is IP 54 up to IP 67. The metal or thermoplastic enclosures are available in two standard sizes. They have a good resistance to oil and petroleum spirit.
The user can choose from several combinations of NC and NO contacts. The switches are connected through screw terminals or plug-in connectors. The ZSM 241 with electrical reset is supplied with connecting cable. Some switches have an additional wiring compartment cover, which means that the contacts are never exposed, not even when the switch cover is opened. In this case, the cables can be smoothly connected by means of the cage clamps.
