PS216-Q200 / -Q210 pull-wire switch
The Schmersal Group launches 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 . Key benefits of the new PS216 switch are its compact dimensions and extreme versatility , enabled thanks to high degrees of protection under EN 60529 and suitable for use in a wide range of temperatures .
Thanks to IP66 degree of protection , the PS216 pull-wire switch is protected against dust and strong water jets and thanks to IP67 degree of protection , is also protected against temporary submersion in water . The switch can be used in ambient temperatures ranging from -30 ° C to + 80 ° C .
Another practical benefit is that 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 distinctive features of the PS216 include cable entry via M20 or M12 connector and six different NC / NO contact variants .
