TECHNICAL DATA
APPLICATION
Housing colour:
grey, similar to RAL 7035
Application scenarios include tempera- ture monitoring in control cabinets, machines and housings.
Ambient temperature: 0 to 60 °C Permissible atmospheric humidity: Max. 95% rel. humidity, non-condensing Max. switching voltage: 230 VAC / 50 Hz, 48 VDC Min. switching voltage: 24 VAC / 50 Hz, 24 VDC Min. switching current:
The resistance of the contact transition results in a voltage drop across the con- tact. This can have a strong influence on very small switching signals.
