40.52.9.012.0300

Power Relays, Over 2 Amps Overview

The Finder 40.52.9.012.0300 is a miniature general-purpose electromagnetic relay from the 40 Series, designed for PCB mounting with a 5 mm pin pitch. It features a 12VDC coil and DPST-NO (2 Form A) contact configuration. The unit supports through-hole installation and socketable operation. Key electrical parameters include an 8A rated contact current, 400VAC maximum switching voltage, and standard AgNi contact material. It provides 8mm, 6kV isolation between coil and contacts.

Power Relays, Over 2 Amps Feature Summary

• Miniature form factor optimized for dense PCB layouts
• Socketable design facilitates easy replacement and maintenance
• High isolation rating ensures safety in mixed-voltage applications

Power Relays, Over 2 Amps Applications

• Industrial control panel signal switching
• Consumer electronics power management circuits
• Automotive instrumentation modules

Power Relays, Over 2 Amps Procurement Notes

Verify that the specific suffix '0300' corresponds to the DPST-NO configuration rather than other variants like '0000' which may be DPDT. Confirm coil voltage tolerance matches the 12VDC requirement. Ensure the ordering part number aligns with the required contact material and peak current specifications for the target application load.

Power Relays, Over 2 Amps Selection Notes

Select this model when space constraints require a 5mm pin pitch relay. It is suitable for applications needing single-pole switching with high isolation. Consider the 8A continuous current rating against the expected load. Verify compatibility with standard 40-series sockets if plug-in functionality is required for assembly or service.

Power Relays, Over 2 Amps Part Context

This component belongs to the Finder 40 Series, a range of miniature PCB relays. The series includes various pole configurations such as 1-pole (40.31, 40.51) and 2-pole (40.52) options. The 40.52 variant specifically offers two independent contacts with a 5mm pin pitch, balancing compact size with higher switching capacity compared to narrower pitch alternatives.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes include Finder 40.52.9.012.0000 (DPDT) if dual poles are acceptable, or 40.52.9.012.0301 for similar DC coil applications. Cross-reference pin pitch and contact form strictly. Generic equivalents must match the 5mm pitch and 12VDC coil characteristics.
