Pull wire switch TQ215

3-polewaterproofrobust

The new space-saving range of pull-wire switches from Schmersal is suitable for applications in cramped installation spaces. The dimensions of these compact switches are based on the standards for position switches – EN 50047 and EN 50041. The small pull-wire switches also have a robust metal enclosure, wide temperature range and the high protection class IP67, which makes them suitable for outdoor use and use in challenging environmental conditions, such as in the mining industry, heavy industry and raw materials processing. The TQ215/TQ315 pull-wire switches can be used as signal transmitters, for applications such as starting machinery and plants. The switching command can be triggered at any point along the wire, with wire lengths of up to 25 m available. Pull-wire switches with an emergency stop function are also available in the same compact design. ZQ215/ZQ315 pull-wire emergency stop switches have an unlocking function, which must be actively reset before the next actuation. The advantage of pull-wire switches over mushroom head emergency-stop push buttons is that the emergency-stop function can be triggered anywhere along the wire. With a wire length of up to 25 m available on the ZQ215/ZQ315 pull-wire emergency stop switches, they are capable of safeguarding even large danger areas. Like position switches from Schmersal, this series is also modular in design, and all pull-wire switches can be individually configured and equipped with up to three switching contacts, various connection options as well as LED status indicators.
