Finder 32.21.7.048.4300 PCB Power Relay, 1 CO, 6 A, 48 V DC Coil

Switching loads on a printed circuit board often requires a component that combines compact dimensions with reliable performance. The Finder 32.21.7.048.4300 PCB power relay addresses this need with a 1 CO (SPDT) contact rated for 6 A at 250 V AC. Its 48 V DC coil consumes only 200 mW, making it suitable for energy-conscious designs.

Who is it for

This relay is intended for engineers and technicians designing PCB-based control systems, automation equipment, or power management circuits. It fits applications where a single changeover contact must handle moderate power loads while maintaining reinforced insulation between coil and contacts.

• Rated current: 6 A at 250 V AC
• Coil voltage: 48 V DC, power 200 mW
• Reinforced insulation with 5 kV AC dielectric strength
• AgNi contact material for long electrical life
• PCB mount with 5 pins

Specifications

• Series: 32.21
• Coil resistance: 11520 Ω
• Max switching voltage: 400 V AC
• Max switching power (AC1): 1500 VA
• Electrical life (at rated load): 100 x 10^3 cycles
• Mechanical life: 10 x 10^6 cycles
• Operating temperature range: -40 to +85 °C
• Approvals: VDE, UL, CSA, RINA, IMQ, GOST, CCC, CQC

Tips

When designing the PCB layout, ensure adequate creepage and clearance distances to maintain the reinforced insulation. The relay's low coil power makes it compatible with direct drive from logic circuits, but verify the coil current against the driver's capability.
