40.61.7.048.1000 Finder Miniature PCB relay 1pole 16A DC 48V

Why Choose the Finder 40.61.7.048.1000 Miniature Power Relay?

The Finder 40.61.7.048.1000 is a compact 16 A miniature electromechanical power relay designed for industrial automation, electrical load switching and electronic control systems. Part of the Finder Series 40, this relay combines a sensitive DC operating coil with a single changeover contact, providing a practical switching solution for equipment using a 48 V DC control supply.

Featuring a 48 V DC sensitive coil, one changeover contact (SPDT / 1 CO) and a 16 A rated contact current, the Finder 40.61.7.048.1000 enables a low-power control circuit to switch compatible electrical loads. Its silver cadmium oxide (AgCdO) contact material is the standard contact specification for this Series 40.61 variant, offering robust electromechanical switching characteristics.

The relay features a compact 12.4 × 29 × 25 mm housing and 5 mm contact pin pitch, making it suitable for printed circuit boards and compatible relay socket installations. Its monostable operating mechanism, sensitive coil and established Series 40 construction make it a practical choice for machine builders, electronics engineers and industrial control panel manufacturers.

Reliable 48 V DC Control with High-Current Changeover Switching

The Finder 40.61.7.048.1000 uses an electromagnetic coil to operate a single changeover contact. When the appropriate 48 V DC control voltage is applied, the relay energises and transfers its common contact from the normally closed terminal to the normally open terminal. When coil power is removed, the contact returns to its normal position.

The sensitive DC coil has a nominal consumption of 0.5 W and draws approximately 10 mA at its rated voltage. This makes the relay suitable for compatible electronic controllers and industrial control circuits where low coil power consumption is desirable. Its 16 A changeover contact provides a separate switching circuit for electrical loads, subject to the applicable contact ratings and operating conditions.

The relay's AgCdO contact material is an important characteristic of this specific variant. Silver cadmium oxide contains cadmium, so engineers should verify compliance with applicable environmental legislation, including relevant RoHS restrictions or exemptions, before specifying the relay for new equipment. Alternative Series 40 variants with different contact materials should not be assumed to be direct replacements without checking the complete specification.

For applications involving motors, transformers, capacitive loads or LED drivers, the load's starting current, inrush current and switching frequency should be assessed rather than relying solely on the resistive-load contact rating. Appropriate PCB conductor sizing, relay socket ratings, coil suppression and circuit protection should also be considered.
