AZ9711-1C-12DSETK

Relay Automotive Overview

The AZ9711-1C-12DSETK is a single-pole double-throw (SPDT) automotive relay manufactured by American Zettler. It features a nominal coil voltage of 12 VDC and supports a maximum switching current of 45 Amps in a compact, epoxy-sealed package designed for high in-rush applications. The component utilizes a PC board mounting style with a small footprint compatible with European-style standards. It offers vibration and shock resistance, making it suitable for demanding automotive environments where reliable contact switching is critical.

Relay Automotive Feature Summary

• Epoxy sealed construction for environmental protection
• High current switching capability up to 45 Amps
• Compact footprint with vibration and shock resistance

Relay Automotive Applications

• Automotive power distribution systems
• High in-rush load control circuits
• Vehicle accessory switching modules

Relay Automotive Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required coil voltages and contact ratings. Confirm that the epoxy seal type matches the environmental protection needs of the target application. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Ensure the PCB mounting dimensions align with the design layout before finalizing procurement orders.

Relay Automotive Selection Notes

Select this relay when a robust SPDT configuration is required for automotive loads exceeding standard relay capacities. The 12 VDC coil voltage aligns with common vehicle electrical systems. Consider the 45 Amp rating for heavy-duty applications such as lighting or motor controls. The compact size facilitates integration into space-constrained electronic control units. Verify thermal management requirements given the high current handling capabilities of the device.

Relay Automotive Part Context

This component belongs to the AZ9711 series of automotive relays from American Zettler. The series is characterized by its ability to handle high currents in a miniature form factor. The '1C' designation indicates a Single Pole Double Throw contact arrangement. The '12D' specifies the 12 Volt DC coil operation. This series is engineered specifically for the harsh conditions found in modern automotive electronics.

Relay Automotive Replacement Considerations

The AZ9711-1C-24DET is a confirmed substitute within the same family, differing primarily in having a 24 VDC coil voltage instead of 12 VDC. Both share the SPDT contact configuration and similar current handling characteristics. Ensure the system voltage matches the replacement coil specification before substitution.
