AZ9801-1A-24DH

Relay Automotive Overview

The AZ9801-1A-24DH is a socketable automotive power relay manufactured by American Zettler. It features a single pole single throw normally open (SPST-NO) contact configuration with one Form A. The coil operates on 24VDC with a resistance of 288 Ohms. The contacts support a maximum DC current of 70A and a voltage of 50VDC, handling up to 980W resistive load. The unit measures 26.2mm in width and height, with a length of 40.1mm. It offers 500 Vrms dielectric strength between coil and contacts.

Relay Automotive Feature Summary

• High current capacity of 70A for demanding automotive loads
• Socketable design for easy installation and replacement
• Robust 500 Vrms isolation between control and power circuits

Relay Automotive Applications

• Automotive high-current circuit protection
• Power distribution in vehicle electrical systems
• Industrial control panels requiring heavy switching

Relay Automotive Procurement Notes

Verify the specific suffix 'DH' against the manufacturer's current datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact coil voltage and contact rating required for the target application. Cross-reference physical dimensions with available socket types to guarantee mechanical fitment before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a 70A switching capability is required within standard automotive form factors. The 24VDC coil specification must align with the system's control voltage availability. Consider the socketable nature of the package if maintenance accessibility or rapid replacement is a priority for the end-product design.

Relay Automotive Part Context

This relay belongs to the AZ9801 series, designed specifically for automotive environments. It serves as a robust solution for managing high-power loads where reliability under vibration and thermal stress is critical. The series provides standardized dimensions compatible with common industry sockets.

Relay Automotive Replacement Considerations

Direct substitutes include other 70A SPST-NO automotive relays with identical 24VDC coil specifications and matching footprint dimensions. Verify that alternative parts maintain the same 500 Vrms isolation rating and socket compatibility to ensure seamless integration without redesigning the PCB or housing.
