AZ977-1A-12DSE

Relay Automotive Overview

The AZ977-1A-12DSE is a 20 Amp miniature automotive power relay manufactured by American Zettler. It features an SPST (Single Pole Single Throw) normally open contact arrangement, designated as 1 Form A. The device utilizes a 12 VDC coil for actuation and is designed for socketable installation in compact spaces. Key electrical specifications include a maximum switched current of 20 A and a switching capability up to 20 Amps. The relay is engineered to withstand high in-rush applications and offers vibration and shock resistance suitable for automotive environments.

Relay Automotive Feature Summary

• Compact size with up to 20 Amp switching capability
• Designed for high in-rush applications
• Vibration and shock resistant construction

Relay Automotive Applications

• Automotive electrical systems
• High in-rush load control
• Socketable relay installations

Relay Automotive Procurement Notes

Verify the specific ordering suffix 'SE' against the manufacturer's official documentation to confirm exact terminal configuration, sealing type, or packaging variations. Ensure the application environment matches the relay's rated voltage and current limits. Confirm socket compatibility if direct mounting is not utilized. Cross-reference the part number with the latest datasheet to validate any design changes or obsolescence status before finalizing procurement.

Relay Automotive Selection Notes

Select this component when a 20 Amp capacity is required within a small footprint for automotive use. The SPST configuration is appropriate for simple on/off control circuits. Consider the 12 VDC coil requirement for system compatibility. Evaluate the need for socketability versus direct PCB mounting based on assembly constraints. Verify that the mechanical dimensions fit the available space in the target enclosure.

Relay Automotive Part Context

This relay belongs to the AZ977 series of miniature automotive power relays from American Zettler. The series is characterized by its ability to handle significant currents in a reduced physical size compared to standard automotive relays. The 1A designation indicates the SPST NO contact form, while the 12D specifies the coil voltage. This family is widely used in vehicle applications requiring reliable switching under harsh conditions.

Relay Automotive Replacement Considerations

Compatible substitutes include other 20A automotive relays with SPST NO contacts and 12VDC coils, such as the AZ975-1A-12D or AZ976 series variants, provided pinout and dimensional compatibility are verified. Ensure replacement parts meet the same vibration and in-rush current ratings.
