32.21.7.048.2300 Finder miniature relay 1p, 6A DC 48V

Why Choose the Finder 32.21.7.048.2300 Miniature PCB Relay?

The Finder 32.21.7.048.2300 is a compact, high-performance 48 V DC miniature PCB relay designed for reliable electrical switching in industrial automation, electronic control equipment and printed circuit board assemblies. Part of the Finder Series 32 range, this electromagnetic relay combines a sensitive DC coil with a single normally open contact, providing an efficient solution for controlling electrical loads from low-power electronic circuits.

Featuring a single-pole single-throw normally open (SPST-NO / 1 Form A) contact configuration, the Finder 32.21.7.048.2300 provides straightforward on/off switching. Its contacts are rated at 6 A at 250 V AC for resistive loads, while the 48 V DC coil consumes approximately 200 mW, making it suitable for compact electronic control systems where low coil power consumption is important.

Designed for PCB through-hole mounting, this miniature relay features a compact housing measuring approximately 20 × 10 × 10.7 mm. Its wash-tight construction, wide operating temperature range and dependable electromagnetic operation make it a practical choice for OEM electronics, industrial control boards and automated equipment.

Efficient Normally Open Switching for Electronic Control Systems

The Finder 32.21.7.048.2300 uses an electromagnetic coil to operate a normally open contact. When the specified 48 V DC is applied to the coil, the relay energises and closes its contact, allowing current to flow through the connected load. When the coil is de-energised, the contact returns to its normally open position, interrupting the switched circuit.

Unlike changeover relays that provide both normally open and normally closed outputs, the SPST-NO configuration is intended for applications requiring a single switched output. This makes the relay particularly suitable for enabling electrical loads, activating auxiliary equipment and controlling circuits where a straightforward on/off switching function is required.

The relay's 200 mW sensitive DC coil allows operation from appropriately designed low-power control circuitry, while its 6 A resistive AC switching rating provides useful load-handling capability in a compact PCB-mounted package. The wash-tight housing and through-hole solder terminals support integration into professionally manufactured electronic assemblies. Appropriate driver circuitry, coil suppression and contact protection should be selected according to the application.
