40.51.9.024.0300

Power Relays, Over 2 Amps Overview

The Finder Relays Inc. model 40.51.9.024.0300 is a miniature PCB/plug-in power relay designed for high-current switching applications. It features a non-latching coil type operating at a standard DC voltage of 24VDC with a power consumption of 650 mW. The unit utilizes a single Form A (SPST-NO) contact configuration rated for a maximum current of 12A. This component supports both direct PCB mounting and socketable installation, offering flexibility in system integration while maintaining reliable electrical performance for industrial control circuits.

Power Relays, Over 2 Amps Feature Summary

• High current capacity with a 12A contact rating for robust load switching
• Versatile mounting options supporting both direct PCB insertion and socket usage
• Standard DC coil operation ensuring consistent actuation at 24VDC

Power Relays, Over 2 Amps Applications

• Industrial automation control panels requiring high-current signal switching
• Power distribution units needing compact relay solutions
• Electronic equipment utilizing plug-in modular relay architectures

Power Relays, Over 2 Amps Procurement Notes

Verify the specific contact form against application requirements, as this part number denotes a Single Pole Single Throw Normally Open (Form A) configuration. Confirm that the 12A current rating aligns with the intended load to prevent premature failure. Ensure the selected mounting method, whether direct PCB soldering or use of compatible sockets like the 95 series, matches the assembly process. Cross-reference the 24VDC coil voltage with the system's available power supply rails to guarantee proper operation without under-voltage issues.

Power Relays, Over 2 Amps Selection Notes

Select this component when a normally open switching function is required rather than a changeover contact. The 12A rating distinguishes it from lower-capacity variants within the 40 series, making it suitable for heavier loads. Consider the physical dimensions and pin pitch compatibility if replacing existing designs. Evaluate the need for supplementary modules, such as EMC suppression or coil indication, if the application environment demands enhanced noise immunity or visual status feedback during operation.

Power Relays, Over 2 Amps Part Context

This relay belongs to the Finder Series 40, a line of miniature PCB relays known for their compact footprint and high reliability. The series offers various coil powers and contact configurations to suit diverse electronic design needs. Model 40.51.9.024.0300 specifically addresses applications requiring a simple normally open switch with significant current handling capabilities, fitting into systems where space constraints and high performance are critical design factors.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes within the same series include 40.51.9.024.0000, which shares similar electrical characteristics but may differ in specific contact material certifications or minor mechanical tolerances. Verify that any replacement maintains the SPST-NO contact form and 24VDC coil specification to ensure functional equivalence in the target circuit.
