AZ970E-1A-24D

Relay Automotive Overview

The AZ970E-1A-24D is a miniature power relay designed for automotive applications, manufactured by American Zettler. It features a SPST (1 Form A) contact arrangement with a maximum switching current of 40 Amperes and a maximum switched voltage of 150 VDC. The coil operates at 24 VDC nominal voltage. Typical operate time is 3 ms, while release time is typically 5 ms without coil suppression. The device offers high dielectric strength of 500 VDC between the coil and contacts. Mechanical life expectancy is rated at 5 x 10^6 operations, and electrical life is 1 x 10^5 operations at 40 A resistive load.

Relay Automotive Procurement Notes

Verify the specific ordering suffix to confirm coil voltage and contact configuration match project requirements. Ensure environmental sealing needs are addressed by selecting the appropriate housing variant from the manufacturer's catalog. Confirm RoHS compliance status if required by supply chain regulations. Cross-reference datasheet specifications against application load profiles to ensure operational reliability under expected duty cycles.

Relay Automotive Selection Notes

Select this component based on its 40 Amp capacity and 24 VDC coil requirement. Consider the SPST form A contact arrangement for simple switching tasks. Evaluate the need for sealed versus open versions based on exposure to moisture or contaminants. Verify that the 150 VDC maximum voltage rating aligns with the circuit design parameters before integration.

Relay Automotive Part Context

This relay belongs to the AZ970/AZ971 series of miniature power relays intended for automotive use. The series emphasizes low cost and small footprint while maintaining robust performance characteristics. Variants within the family differ primarily by coil voltage and contact arrangement options, providing flexibility for various automotive electrical architectures.

Relay Automotive Replacement Considerations

Direct substitutes may include other models from the AZ970 series with compatible coil voltages and contact forms. Verify mechanical dimensions and pinout compatibility when considering alternative part numbers from different manufacturers to ensure proper fit and function in existing assemblies.
