Temperature Switch

Our temperature switches from the WTR 600 series combine intelligence and robustness in an innovative sensor series. The compact design is ideal for confined installation spaces and resists harsh environmental conditions, such as strong vibrations. The sensors communicate via a digital RS485 interface and can be freely programmed (e.g., switching point, 2-point control with adjustable hysteresis, etc.).
