40.52.8.110.0000

Power Relays, Over 2 Amps Overview

The Finder Relays Inc. model 40.52.8.110.0000 is a miniature electromechanical relay from the 40 Series, designed for PCB mounting or plug-in applications. It features a double-pole double-throw (DPDT) contact configuration with two Form C sets. The coil operates at 110V AC, while the contacts are rated for a maximum switching current of 8A and a voltage up to 400V AC. The unit utilizes silver-nickel (AgNi) contact material and offers high isolation capabilities.

Power Relays, Over 2 Amps Feature Summary

• Miniature form factor suitable for dense PCB layouts or socket installation
• High electrical isolation with specified creepage and clearance distances
• Dual independent switching circuits via DPDT contact arrangement
• Robust contact construction using silver-nickel alloy for durability

Power Relays, Over 2 Amps Applications

• Industrial control panel signal switching
• HVAC system actuator control
• Automated machinery interface modules
• Power distribution monitoring circuits

Power Relays, Over 2 Amps Procurement Notes

Verify that the specific order matches the 110V AC coil requirement, as this series includes DC variants. Confirm whether the application requires the standard pin pitch or if a socketed version is preferred for maintenance accessibility. Ensure the load current does not exceed the 8A rating under the expected operating temperature conditions to prevent premature contact degradation.

Power Relays, Over 2 Amps Selection Notes

Select this component when a compact DPDT solution is required for AC control signals. The 5mm pin pitch facilitates standard PCB footprint design. Consider the 6KV isolation rating for safety-critical interfaces. This model is appropriate where space constraints limit larger relay sizes but higher current capacity than standard signal relays is necessary.

Power Relays, Over 2 Amps Part Context

This device belongs to the Finder 40 Series, a line of miniature power relays known for their small footprint and high current density. The series distinguishes itself through standardized pin pitches and versatile coil options, allowing designers to mix DC and AC coils within the same mechanical housing family for flexible system architecture.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes include other 40.52 series variants with identical DPDT 8A ratings but different coil voltages, such as 40.52.7.024.0000 for 24V DC. Cross-brand replacements must match the 5.3mm pin pitch and DPDT configuration to ensure mechanical compatibility without PCB redesign.
