40.52.7.024.0001

Power Relays, Over 2 Amps Overview

The Finder Relays Inc. model 40.52.7.024.0001 is a miniature general-purpose electromechanical relay from the 40 series, designed for PCB or plug-in mounting. It features a double-pole double-throw (DPDT) contact configuration with two change-over contacts. The coil operates at a nominal voltage of 24 VDC with a power consumption of 500 mW and a resistance of approximately 846 ohms. The contacts are rated for a maximum switching current of 8 A and a maximum switching voltage of 250 VAC, supporting a load up to 2000 VA. The unit utilizes silver-nickel (AgNi) contact material and offers high isolation capabilities.

Power Relays, Over 2 Amps Procurement Notes

Verify that the specific ordering code matches the DPDT configuration and 24VDC coil requirement. Confirm compatibility with intended PCB footprint or socket type, such as the 90.23 series, if plug-in usage is planned. Ensure environmental conditions align with the specified operating temperature range and sealing standards before finalizing procurement orders.

Power Relays, Over 2 Amps Selection Notes

Select this component when dual independent switching channels are required within a compact volume. The 8A rating supports moderate power loads without requiring larger industrial relays. Consider the 500mW coil power for low-energy control systems. Verify that the 250VAC contact voltage limit meets the application's peak voltage requirements during transient events.

Power Relays, Over 2 Amps Part Context

This relay belongs to the Finder 40 series, a line of miniature electromechanical relays known for their versatility in both surface-mount and through-hole applications. The series is characterized by standardized dimensions and pin pitches, facilitating easy integration into various electronic assemblies. It serves as a robust alternative to solid-state solutions where mechanical isolation is preferred.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes must match the 40.52 series dimensions, DPDT contact layout, and 24VDC coil specifications. Check for equivalent AgNi contact materials and identical 8A current ratings. Verify that any replacement maintains the same 5.3mm pin pitch and isolation distances to ensure physical and electrical compatibility.
