AZ987-1A-12DET

Relay Automotive Overview

The AZ987-1A-12DET is a sealed automotive power relay manufactured by American Zettler. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a 30 A current rating and a 12 VDC coil voltage. The device utilizes through-hole PC pin termination for PCB mounting and operates within an extended temperature range of -40°C to 105°C. Constructed with silver tin oxide contacts, it offers high switching durability and electrical isolation suitable for demanding automotive environments.

Relay Automotive Feature Summary

• Epoxy-sealed construction provides environmental protection against moisture and contaminants
• High current capacity supports heavy-load switching applications in vehicle systems
• Extended operating temperature range ensures reliable performance in harsh conditions

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle heating and cooling systems
• Power distribution modules

Relay Automotive Procurement Notes

Verify the specific part number suffix to confirm the epoxy-sealed variant, as unsealed versions may exist within the same series. Ensure the ordering documentation explicitly references the AZ987-1A-12DET designation to avoid confusion with similar non-sealed or different contact configuration models. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance status or material composition changes.

Relay Automotive Selection Notes

Select this component when a robust, sealed relay is required for automotive loads exceeding standard signal capabilities. The 30 A rating makes it suitable for high-power accessories, while the 12 VDC coil aligns with standard vehicle electrical architectures. Consider the physical dimensions and through-hole mounting requirements during PCB layout design to ensure adequate clearance for the sealed housing.

Relay Automotive Part Context

This model belongs to the AZ987 series of miniature automotive relays produced by American Zettler. The series is designed specifically for automotive applications requiring compact form factors with high reliability. Variations within the series typically differ by contact configuration, coil voltage, and sealing options, allowing designers to tailor the solution to specific circuit demands.

Relay Automotive Replacement Considerations

Direct substitutes include other sealed automotive relays from American Zettler with identical 30 A ratings and 12 VDC coils, such as the AZ9871-1A-12DET. Verify that any replacement maintains the SPST-NO contact form and through-hole pin compatibility to ensure mechanical and electrical interchangeability.
