Power Relays, Over 2 Amps Procurement Notes

Verify the specific ordering suffix to confirm the exact coil voltage and contact configuration, as variations exist within the series. Ensure compatibility with standard relay sockets if socketed operation is required. Confirm RoHS compliance status for environmental regulations. Cross-reference the pin pitch and mechanical dimensions against the target PCB layout or enclosure specifications before finalizing procurement orders.

Power Relays, Over 2 Amps Selection Notes

Select this component when a 28 VDC coil drive is necessary alongside a 10 A switching capacity. The SPST-NO contact form is suitable for simple on/off control logic. Consider the physical footprint constraints due to its miniature design. Evaluate thermal dissipation requirements given the 650 mW coil power consumption. Ensure the application voltage does not exceed the 400 VAC rating for safe operation.

Power Relays, Over 2 Amps Part Context

This relay belongs to the Finder Series 40, a line of miniature PCB and plug-in relays known for their robust construction and versatility. The series typically offers various coil voltages and contact arrangements to suit diverse control needs. Models in this family often share common mechanical interfaces, allowing for standardized socket usage across different electrical configurations within the same product line.

Power Relays, Over 2 Amps Replacement Considerations

Compatible substitutes include other 28 VDC coil relays with matching 10 A ratings and SPST-NO contacts. Verify that alternative parts maintain the same 12.4 x 25 x 29 mm dimensions and pin pitch to ensure mechanical fit. Check for equivalent coil power consumption to avoid thermal issues in enclosed spaces.
