Reliable 125 V AC Switching for Industrial Control Applications

The Finder 40.61.8.125.0000 provides an effective means of controlling electrical loads using a 125 V AC control circuit. Its single-pole changeover arrangement enables switching between normally open and normally closed contact paths, supporting a wide range of industrial control, signalling and automation functions.

With a 16 A contact rating and compact PCB-mounted construction, this relay is suitable for applications where switching capability and efficient use of installation space are important. Its electromechanical design enables a control circuit to operate a separate load circuit without requiring a direct electrical connection between the coil and contacts.

For reliable operation, the connected load, switching frequency, contact utilisation category and control supply must remain within the manufacturer's specified operating limits. In particular, inductive loads and loads with high inrush currents may require additional consideration when selecting the relay.

Typical Applications

• Industrial electrical control panels.
• Automation and machinery control systems.
• Printed circuit board switching assemblies.
• Electrical equipment and appliance control.
• Control and signalling circuits.
• Auxiliary switching and interlocking applications.
• Industrial electronic interface modules.
• OEM electrical and electronic equipment manufacturing.
• Maintenance and replacement of compatible miniature relays.
