45.71.7.048.1310 Finder Miniature PCB relay 1pole 16A DC 48V

Why Choose the Finder 45.71.7.048.1310 High-Temperature Power Relay?

The Finder 45.71.7.048.1310 is a high-performance 16 A electromechanical power relay designed for dependable electrical switching in industrial automation, heating equipment, appliances and electronic control systems. Part of the Finder 45 Series, this specialist relay combines a sensitive DC coil, high-temperature capability and robust electrical connections in a compact PCB-compatible design.

Featuring a 48 V DC sensitive electromagnetic coil and a single-pole normally open (SPST-NO / 1 NO) contact, the relay enables a low-power DC control circuit to switch a separate electrical load. Its Faston 250 contact connections, combined with PCB mounting terminals, make it particularly suitable for equipment where secure load connections and reliable switching are essential.

With a 16 A rated contact current, 250 V AC rated contact voltage and an operating ambient temperature range extending to +125 °C, the Finder 45.71.7.048.1310 is engineered for demanding applications. Its 360 mW sensitive coil, silver nickel contacts and reinforced coil-to-contact insulation make it a practical choice for OEM manufacturers and industrial equipment designers.

Reliable High-Temperature Switching with Faston 250 Connections

The Finder 45.71.7.048.1310 operates through a sensitive electromagnetic coil that controls a single normally open power contact. When the 48 V DC coil is energised, the contact closes and completes the external load circuit. When coil power is removed, the contact opens again, making the relay suitable for applications requiring controlled on/off operation.

The Finder 45.71 relay design is particularly suited to equipment operating in elevated ambient temperatures. Its +125 °C temperature capability, reinforced electrical insulation and Faston 250 contact terminals support integration into demanding industrial and commercial equipment. The combination of PCB mounting and flat blade contact connections also helps accommodate electrical assemblies requiring separate control and load connection arrangements. Appropriate conductor sizing, contact protection and adherence to the manufacturer's electrical ratings are essential for reliable operation.
