If inductive loads or stronger currents are switched through, the gold
plating on the relay contact surface will be permanently damaged.
The contact is then no longer suitable for switching low-voltage
circuits.
Inductive loads also result from the connection to a PLC input or
output and/or in combination with long cables. It is imperative that you
take measures to extinguish sparks to protect the relay contact (e.g. Z
diode) or use an electronic version with transistor output.
