Versatile pull-switch for automation

23 December 2021

SCHMERSAL GROUP's PS216-Q200/-Q210 pull-wire switch can be used as a signal generator to perform multiple functions in one pull.

The Schmersal Group has launched a new pull-wire switch that can be used as a signal generator to start machines, open electrically operated guard doors and gates, and as a light switch in lift shafts. The company claims the key benefits of the PS216 switch are its compact dimensions, versatility, protection under EN 60529 and its suitability for use in a wide range of temperatures.  
Because of its IP66 protection, the PS216 pull-wire switch is protected against dust and strong water jets and because of IP67 protection, it is also protected against damage from temporary submersion in water. The switch can be used in ambient temperatures ranging from -30°C to +80°C.  
The PS216 operates according to the ‘start/stop principle’ in that it remains switched on after initial actuation and subsequent release. Only when the switch is actuated and released a second time is the latch released and the switch switched off. 
The PS216 pull-wire switch comes in two versions – the Q200 has a holding force of 45 N and is suitable for wire lengths of up to 50 m, while the Q210 has a holding force of 70 N and can be used with wires stretching up to 100 m. Pulling on the pull wire actuates the switch function in the pull-wire switch.   
Other features of the PS216 include cable entry via M20 or M12 connector and six different NC/NO contact variants.
