Technical Data
A large variety of
microswitches offers different electrical ratings and hysteresis for many applications. Wetted parts: Electrical ratings and hysteresis: Weight: P1H-...: approx. 1.2 kg Repeatability: Diaphragm:Process connection:NBROptional: FKM, PTFE
Aluminium, anodized
Optional: stainless steel 1.4401 ±2 % at constant temperature Set point adjustment: Turn the adjustment screw clockwise to increase the set point. Switching rate: max. 20/min Temperature range: -30 °C... +70 °C Inherent safety: The switches are also applicable for inherent safety applications. Add "Exi" in case of ordering. The following max. values are valid when using those switches: Umax = 28 V Imax = 50 mA System of protection IP00 Approval: NACE Housing: Process connection: Housing:
