32.21.7.048.2000 Finder miniature relay 1p, 6A DC 48V

Why Choose the Finder 32.21.7.048.2000 Miniature PCB Relay?

The Finder 32.21.7.048.2000 is a compact 48 V DC electromagnetic PCB relay designed for dependable switching in industrial control systems, electronic equipment and printed circuit board assemblies. Part of the Finder Series 32 range, this low-profile relay combines a sensitive DC coil with a single-pole changeover contact arrangement, making it a practical solution for applications requiring electrical isolation between control circuitry and switched loads.

Featuring a single-pole double-throw (SPDT) contact configuration, the Finder 32.21.7.048.2000 provides both normally open and normally closed switching paths. Its contacts are rated at 6 A at 250 V AC for resistive loads, while the 48 V DC coil consumes just 200 mW, helping minimise power requirements in electronic control designs.

Designed for PCB through-hole mounting, the relay measures approximately 20 × 10 × 10.7 mm, making it suitable for space-conscious electronic assemblies. Its sealed construction, wide operating temperature range and compact dimensions make it a versatile choice for OEM equipment, automation controls and industrial electronic switching applications.

Compact Electromagnetic Switching for PCB Control Circuits

The Finder 32.21.7.048.2000 operates using an electromagnetic coil that changes the position of a mechanical contact when energised. Applying the specified 48 V DC to the coil causes the changeover contact to transfer between its normally closed and normally open positions. When the coil is de-energised, the relay returns to its normal state, allowing low-power electronic circuitry to control a separate electrical load.

The SPDT contact arrangement offers flexibility for control circuit design, including selecting between two output paths, switching an electrical load or providing an interlocking signal. The 6 A at 250 V AC resistive load rating makes the relay suitable for appropriately rated switching duties, while the sensitive 200 mW DC coil reduces the power required from the controlling circuit.

Its through-hole PCB terminals enable direct integration into electronic assemblies without a separate relay socket. The compact housing and sealed construction are particularly useful in equipment where PCB space, electrical isolation and consistent switching performance are important. Engineers should confirm the applicable contact ratings, load characteristics and PCB layout requirements before installation.
