40.52.7.018.0000

Power Relays, Over 2 Amps Overview

The Finder Relays, Inc. model 40.52.7.018.0000 is a miniature general-purpose power relay designed for printed circuit board mounting and plug-in applications. It features a double-pole double-throw (DPDT) contact configuration with an 8 A rated switching current. The coil operates at 18 VDC. Constructed with silver-nickel contacts, the unit supports a maximum switching voltage of 250 VAC and handles up to 2000 VA load capacity. The device utilizes a through-hole termination style and is sealed against flux protection.

Power Relays, Over 2 Amps Feature Summary

• Features a DPDT contact arrangement providing two independent switching paths for complex circuit control.
• Incorporates a robust silver-nickel contact material system to ensure reliable electrical conductivity and extended operational lifespan under varying load conditions.
• Designed with a compact miniature form factor suitable for high-density PCB layouts and standard plug-in socket integration.

Power Relays, Over 2 Amps Applications

• Industrial automation control panels requiring compact switching solutions
• General-purpose signal and power distribution in electronic equipment
• HVAC systems utilizing low-voltage DC control circuits

Power Relays, Over 2 Amps Procurement Notes

Verify that the specific 18 VDC coil voltage aligns with the target control circuit design to prevent improper actuation or damage. Confirm that the DPDT contact configuration meets the required switching logic for the application. Ensure compatibility with standard 5.3 mm pin pitch sockets if plug-in usage is intended. Check RoHS compliance status for regulatory adherence in restricted substance environments.

Power Relays, Over 2 Amps Selection Notes

Select this component when a DPDT configuration is necessary within a space-constrained environment. The 18 VDC coil specification requires careful matching to available control voltages. Consider the 8 A current rating to ensure adequate margin for the intended load. Evaluate the need for plug-in versatility versus direct PCB soldering based on maintenance requirements.

Power Relays, Over 2 Amps Part Context

This relay belongs to the Finder Series 40 family of miniature PCB relays. The series is characterized by its small footprint and standardized 5.3 mm pin pitch, facilitating easy replacement and socket compatibility. It serves as a versatile switching element for both signal and power applications in modern electronic assemblies.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes must match the DPDT topology, 18 VDC coil voltage, and 8 A current rating. Verify physical dimensions and pin spacing compatibility with existing footprints or sockets before implementation.
