AZ971E-1A-24DE

Relay Automotive Overview

The AZ971E-1A-24DE is a miniature power relay designed for automotive applications, manufactured by American Zettler. It features an SPST (1 Form A) contact arrangement with a switching current rating of up to 45 Amperes and a maximum switched voltage of 150 VDC. The coil operates at 24 VDC nominal voltage. The device offers mechanical life expectancy of 5 x 10^6 operations and electrical life of 1 x 10^5 operations at 40 A resistive load. Dielectric strength is rated at 500 VDC between coil and contacts.

Relay Automotive Feature Summary

• Compact footprint suitable for space-constrained automotive environments
• High current switching capability in a miniature package
• Resistant to vibration and shock for reliable operation
• Designed specifically for high in-rush current applications

Relay Automotive Applications

• Automotive power distribution systems
• High current accessory control circuits
• Industrial equipment requiring robust switching
• General purpose heavy-duty relay applications

Relay Automotive Procurement Notes

Verify the specific suffix 'DE' against the manufacturer's latest datasheet to confirm sealing type and terminal configuration. Ensure the 45A rating aligns with the actual load profile, as some variants may be rated for 40A. Confirm coil voltage tolerance and operating temperature range requirements match the target application environment before finalizing procurement.

Relay Automotive Selection Notes

Select this model when high current capacity is required in a small form factor. The SPST configuration provides simple on/off control. Consider the 24VDC coil requirement for system compatibility. Evaluate the sealed construction option if environmental protection is necessary. Compare against standard automotive relays to ensure the compact size meets spatial constraints while providing sufficient current handling.

Relay Automotive Part Context

This component belongs to the AZ971 series of miniature power relays from American Zettler. The series is characterized by its small European-style footprint and high switching capabilities. Variants within the series differ primarily by coil voltage and contact arrangement. This specific model targets automotive markets where reliability under vibration and high current loads is critical.

Relay Automotive Replacement Considerations

Direct substitutes include other models from the AZ971 series with compatible coil voltages, such as AZ971E-1A-12DE for 12VDC applications. Cross-reference pinout dimensions and contact ratings with alternative manufacturers like Omron or Panasonic if sourcing changes are required. Verify that any replacement maintains the same SPST configuration and current carrying capacity.
