The non-contact safety switches from the STS series are used for monitoring the position of doors and guards in machine safety applications.
Up to 30 switches can be wired in series while maintaining a CAT 4 / PLe safety level. An additional signal output and a tri-color LED indicator are available to identify the status of individual switches. Integrated automatic reset, manual reset and EDM functionality are possible. The robust 400mA outputs can also be used to drive considerable loads.
The STS sensor/actuator sets can be purchased in coded, fully coded (teachable), and unique (match made by factory) versions in compliance with the coding type requirements set forth in ISO 14119.
The compact size, 5 directions of approach and IP6k9k (IP69K) protection offer the flexibility to use these switches in virtually any applications.
M12, T-connectors are available to facilitate series connection of the switches outside the control panel. It is even possible to connect them in series while retrieving the annunciation signal for each individual switch.
Note more models are available, please call for more information.
