AZ9711-1A-24DET

Relay Automotive Overview

The AZ9711-1A-24DET is a 45 Amp automotive relay manufactured by American Zettler. It features a 24 VDC coil and SPST-NO (1 Form A) contact arrangement. The component supports switching voltages up to 150VDC with a maximum current rating of 30A for continuous operation, though it handles in-rush currents up to 45A. The must-operate voltage is specified at 13.9 VDC. This through-hole device is epoxy sealed for reliability in high-current applications.

Relay Automotive Feature Summary

• High current switching capability designed for demanding automotive environments
• Epoxy sealed construction provides environmental protection
• Compact footprint suitable for space-constrained installations

Relay Automotive Applications

• Automotive electrical systems
• High in-rush current applications
• Industrial control circuits

Relay Automotive Procurement Notes

Verify the specific contact configuration matches the design requirement, as the AZ9711 series includes both SPST-NO and SPDT variants. Confirm that the 24VDC coil voltage aligns with the system power supply. Ensure the PCB layout accommodates the through-hole package dimensions and thermal requirements associated with high-current switching operations.

Relay Automotive Selection Notes

Select this model when a single normally open contact is required for loads up to 45 Amps. The 24VDC coil specification suits standard automotive electrical architectures. Consider the epoxy seal if exposure to moisture or contaminants is expected. Verify that the 150VDC switching limit meets the circuit voltage requirements.

Relay Automotive Part Context

This part belongs to the AZ9711 series of automotive relays from American Zettler. The series is characterized by robust construction and high current handling capabilities. Variants within the series differ primarily by contact form (Form A or Form C) and coil voltage ratings, allowing customization for specific circuit topologies.

Relay Automotive Replacement Considerations

Cross-reference with other 45A automotive relays featuring SPST-NO contacts and 24VDC coils. Ensure mechanical footprint and pinout compatibility before substitution. Verify that alternative components meet the same 45A in-rush and 30A continuous current ratings.
