Its flux-proof construction protects against dust and solder flux, extending service life even in less-than-ideal conditions. The plug-in socket compatibility allows quick replacement without rewiring, reducing downtime.

Ideal use cases

• Interface between PLC outputs and higher-power loads
• Switching of contactors, valves, and small motors
• Signal multiplication and isolation in control circuits
• Building automation for lighting and HVAC control
• General industrial machinery and equipment

Good to know

For optimal performance, use with Finder Series 97 sockets and retain clips. The relay is suitable for ambient temperatures from -40 °C to +70 °C, making it versatile for both cold storage and hot process areas. Always verify coil polarity for DC operation and ensure the load does not exceed the rated switching power.
