Reliable Electrical Switching for Industrial Control Systems
Electromagnetic power relays such as the Finder 65.31.8.024.4000 allow electrical loads to be controlled through a separate low-voltage control circuit. When the 24 V AC coil is energised, the normally open contact closes while the normally closed contact opens. This complementary switching action enables control of two circuits with opposite operating states, making the relay suitable for automation, equipment control and electrical switching applications.
The Finder 65 Series is designed for industrial installations requiring robust electrical switching and straightforward integration. Its 20 A contact rating, durable AgSnO₂ contact material and practical Faston connections support dependable operation in electrical control cabinets, heating equipment and machinery. The rear flange mounting arrangement provides a secure mechanical installation, while the separate coil and contact circuits allow electrical loads to be controlled without routing their operating current through the control switch.
Typical Applications
Industrial automation and machinery control systems.
Electrical control cabinets and panel assemblies.
Industrial lighting and lighting control circuits.
Heating equipment and temperature control systems.
HVAC equipment and building services control.
Electrical load switching and power management.
OEM machinery and equipment manufacturing.
Control circuits requiring complementary normally open and normally closed switching.
