Temperature switch with two switching outputs
› Temperature switch with two adjustable switch points
› Simple switching point setting by means of two setting rings allowing optimum reading
› Mechanical locking prevents inadvertent switching point manipulation
› Particularly good response dynamics and very short power-on delay time
› Installation length 250 mm
› High vibration and shock resistance
› Certification acc. to EU direction
Technical Features
Temperature switch with the measuring thermistor Pt 1000 and two adjustable temperature switching points. Two adjusting rings are provided with scale
and their position is protected with a mechanical lock. The stainless-steel body is provided with connecting thread G 1/2 with FKM sealing ring. The needed
installation length for the measuring stem is 250 mm. An electric connection is realized by four-pin connector M12 x 1. The temperature switch is suitable for
industrial usage thanks to robust design, vibration and shock resisted.
Outputs: two switching contacts (pin 2 and pin 4)
