AZ971-1A-24DE

Relay Automotive Overview

The AZ971-1A-24DE is a 24VDC automotive power relay manufactured by American Zettler. It features a single pole single throw normally open (SPST-NO) contact configuration, also designated as Form A. The device supports a switching capability of up to 40 amps with a coil resistance of 362 ohms. Designed for through-hole mounting, it utilizes a compact footprint measuring approximately 21.1mm by 26.2mm. The relay operates with a non-latching coil type and includes a 5 ms operate time.

Relay Automotive Feature Summary

• High current switching capability in a compact form factor
• Single pole single throw normally open contact configuration
• Compatible with 24VDC coil voltage applications

Relay Automotive Applications

• Automotive electrical systems
• Industrial control circuits
• Power distribution management

Relay Automotive Procurement Notes

Verify the specific suffix 'E' or absence thereof against the manufacturer's latest documentation, as variations may exist between AZ971-1A-24DE and AZ971-1A-24D. Confirm that the required contact form is strictly SPST-NO (Form A) rather than Form C. Ensure the operating environment temperature range aligns with the component's rated specifications before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a 24VDC coil voltage is required for the control circuit. The SPST-NO configuration is suitable for simple on/off switching loads. Consider the 40 amp rating to ensure adequate capacity for the intended load. Verify physical space constraints due to the specific 21.1mm x 26.2mm dimensions for PCB integration.

Relay Automotive Part Context

This part belongs to the AZ971 series of automotive relays from American Zettler. The series offers various contact forms including Form A, B, and C, and coil voltages up to 24VDC. The AZ971-1A-24DE specifically denotes the 24VDC coil variant with a normally open contact arrangement, designed for high-current automotive and industrial applications.

Relay Automotive Replacement Considerations

The AZ971-1A-24D is a closely related variant within the same series. Verify if the 'E' suffix indicates a specific packaging or terminal variation. Cross-reference pinouts and mechanical dimensions to ensure compatibility with existing socket designs or PCB layouts.
