AZ9731-1C-24DC1

Relay Automotive Overview

The AZ9731-1C-24DC1 is a Mini-ISO automotive relay manufactured by American Zettler. It features a 24VDC coil voltage and SPDT (1 Form C) contact arrangement. The device supports a 40A contact rating with quick connect terminals. It is designed for high in-rush applications, offering vibration and shock resistance. The unit operates at high temperatures up to 125°C and includes a compact footprint suitable for automotive use.

Relay Automotive Feature Summary

• SPDT contact configuration for versatile switching control
• Quick connect terminal design for simplified installation
• High operating temperature capability up to 125°C
• Resistance to vibration and shock for automotive durability

Relay Automotive Applications

• Automotive power distribution systems
• Vehicle lighting circuits
• Motor control applications
• General vehicle electrical switching

Relay Automotive Procurement Notes

Verify the specific suffix '1C' confirms the SPDT contact form and '24DC1' indicates the 24VDC coil variant. Ensure the application environment does not exceed the specified 125°C operating limit. Confirm that the quick connect terminals match the harness connector specifications. Check if additional sealing or mounting brackets are required for the specific chassis location.

Relay Automotive Selection Notes

Select this model when a 40A switching capacity is required within a Mini-ISO form factor. The SPDT configuration allows for common, normally open, and normally closed connections. Consider the 24VDC coil requirement against the vehicle's electrical system. Evaluate the thermal environment to ensure it remains within the 125°C operational range.

Relay Automotive Part Context

This component belongs to the AZ9731 series of miniature power relays designed specifically for automotive environments. It shares the general robust construction and high current handling capabilities of the family while providing specific SPDT functionality. The Mini-ISO standard ensures compatibility with common automotive relay sockets and mounting configurations.

Relay Automotive Replacement Considerations

Direct substitutes include other Mini-ISO SPDT relays with 24VDC coils and 40A ratings. Verify pinout compatibility and terminal type before substitution. Cross-reference part numbers such as AZ9731-1C-12DC1 if coil voltage differs. Ensure mechanical dimensions align with existing mounting spaces.
