Contact reliability To ensure a high switching reliability, we recommend a minimum load of:
With silver contacts:
AC / DC = 24 V, 100 mA
For gold-plated contacts ("702" symbol):
AC / DC = 10 V, 5 mA

Ambient
temperature influence
based on the
control range /
limit value range When the ambient temperature on the case deviates from the calibration ambient temperature of 22 °C,
a switching point offset occurs.
Higher ambient temperatures = lower switching point
Lower ambient temperature = higher switching point
