Description
TK7255CLFG12-QKPKG / US
- Simple switch point setting by means of two setting rings allowing optimum reading
- Setting of the switch points without system temperature being applied
- Two switching outputs with fixed hysteresis
- Particularly good response dynamics and very short power-on delay time
- Mechanical locking prevents inadvertent switch point manipulation
