AZ971E-1A-12D

Relay Automotive Overview

The AZ971E-1A-12D is a 12VDC automotive relay manufactured by American Zettler. It features an SPST Normally Open (1 Form A) contact arrangement with a 45A switching capacity. The device operates at nominal coil voltage of 12VDC, with typical operate and release times of 7ms and 5ms respectively. It supports resistive loads up to 840W and withstands dielectric strength of 500 Vrms between coil and contacts. The unit offers mechanical life expectancy of 1x10^7 operations and electrical life of 1x10^5 operations at rated load.

Relay Automotive Feature Summary

• Compact European-style footprint suitable for space-constrained automotive applications
• High current switching capability within a small form factor
• Available in open, covered, or sealed epoxy configurations

Relay Automotive Applications

• Automotive high-current circuit switching
• Vehicle accessory power control
• 12V DC system load management

Relay Automotive Procurement Notes

Verify the specific suffix designation to confirm the physical configuration, as the base model may be offered in open, covered, or sealed variants. Ensure the required contact arrangement matches the 1 Form A specification. Confirm compliance requirements such as RoHS status if applicable to the specific manufacturing batch. Cross-reference the datasheet version to ensure accurate timing and life expectancy data for the production lot.

Relay Automotive Selection Notes

Select this component when a compact 12V automotive relay with 45A capacity is required. The SPST-NO configuration is standard for simple on/off control circuits. Consider the sealed variant if environmental protection against moisture or dust is necessary. Verify that the 12VDC coil voltage aligns with the vehicle's electrical system. The small footprint allows for dense PCB layouts compared to larger industrial relays.

Relay Automotive Part Context

This part belongs to the AZ971 series of automotive relays from American Zettler. The series is characterized by its small European-style footprint and high current density. The AZ971E-1A-12D specifically denotes the 12V coil voltage and SPST-NO contact type. The 'E' suffix often indicates a specific terminal or sealing configuration within the product line.

Relay Automotive Replacement Considerations

Direct substitutes include other 12V SPST-NO automotive relays with similar 45A ratings and compatible pinouts. Check datasheets for equivalent mechanical dimensions and coil resistance values. Verify that alternative parts meet the same dielectric strength and life expectancy standards.
