65.31.8.048.4000 Finder Power relay 1NO1 NC 20A 48V

Why Choose the Finder 65.31.8.048.4000 Power Relay?

The Finder 65.31.8.048.4000 is an industrial electromagnetic power relay from the Finder 65 Series, designed for dependable electrical switching in machinery, automation and electrical control equipment. Featuring a 48 V AC operating coil and a single normally open contact (1 NO), this relay provides a practical interface between control signals and electrical loads.

The Finder 65 Series is intended for power-switching applications where a robust electromechanical relay is required. The 65.31 configuration offers a straightforward normally open switching function: when the operating coil is energised, the contact closes to complete the connected load circuit, and when the coil is de-energised, the contact returns to its open position.

With its 48 V AC coil and industrial power relay construction, the Finder 65.31.8.048.4000 is suitable for compatible electrical control assemblies, equipment manufacturers and machinery applications. It is particularly useful where a control circuit must operate a separate electrical load through an electrically isolated switching contact.

Key Advantages

• 48 V AC operating coil for compatible industrial AC control supplies.
• Single normally open contact (1 NO) provides straightforward on/off switching.
• Industrial power relay construction suitable for electrical control equipment.
• Electromechanical operation provides separation between the operating coil and switched circuit.
• Monostable operation returns the contact to its normally open position when de-energised.
• Suitable for auxiliary switching and load-control applications.
• Can be integrated into compatible machinery and OEM electrical assemblies.
• Part of the established Finder 65 Series power relay family.

Key Features

• Finder 65 Series electromagnetic power relay.
• 48 V AC nominal coil voltage.
• Single normally open contact (1 NO / SPST-NO).
• Single-pole electrical switching arrangement.
• AC-operated electromagnetic coil.
• Designed for compatible AC control circuits.
• Normally open contact closes when the coil is energised.
• Monostable, non-latching switching mechanism.
• Electrical separation between control and load circuits.
• Suitable for industrial equipment, machinery and auxiliary power switching.

Reliable Single-Pole Switching for Industrial Equipment

The Finder 65.31.8.048.4000 provides a convenient method of controlling an electrical load from a separate 48 V AC control circuit. When the coil receives its nominal operating voltage, the electromagnetic mechanism closes the normally open contact, allowing the connected circuit to operate.

Its single-pole normally open arrangement is suited to applications where a load should remain disconnected until an intentional control signal is applied. This operating principle is useful in machinery sequencing, auxiliary control, industrial signalling and automated equipment.

For dependable service, the relay should be installed with suitable mechanical support, wiring and protective devices. Contact current, voltage and switching-duty limits must be matched to the connected load, particularly for motors, inductive equipment and circuits with high inrush currents.

Typical Applications

• Industrial automation and electrical control systems.
• 48 V AC machinery control circuits.
• Auxiliary electrical load switching.
• Manufacturing and production equipment.
• Industrial process control systems.
• Electrical control panel assemblies.
• Building services and equipment automation.
• Industrial signalling and control interfaces.
• OEM machinery and electrical equipment.
• Single-circuit switching applications requiring a normally open contact.
