A61AS12VDC.9

Relay Automotive Overview

The A61AS12VDC.9 is a non-latching automotive relay from the CIT Relay and Switch A6 series, designed for high-capacity switching applications. It features a single-pole single-throw normally open (SPST-NO) contact arrangement rated for up to 30A at 14VDC under standard conditions. The coil operates on 12VDC with a current draw of 75mA and resistance of 160 Ohms. Key electrical parameters include a maximum switching voltage of 75VDC, contact material of AgSnO2, and an initial contact resistance below 30 milliohms. The device supports PCB pin mounting and complies with RoHS standards.

Relay Automotive Feature Summary

• Non-latching coil design suitable for continuous or intermittent duty cycles
• High current capacity with SPST-NO configuration for reliable load control
• Robust contact construction using silver tin oxide material for durability
• Compatible with standard PCB pin mounting for automated assembly

Relay Automotive Applications

• Automotive lighting circuits
• Lawn care and maintenance equipment
• General purpose industrial switching
• Accessory power distribution in vehicles

Relay Automotive Procurement Notes

Verify the specific suffix designation when ordering, as variations such as .9D may indicate distinct packaging or handling specifications compared to the base model. Confirm that the required contact form matches the SPST-NO configuration, as alternative variants like A61CS offer different contact arrangements. Ensure compatibility with the target PCB footprint and verify that the 12VDC coil voltage aligns with the system's power supply architecture before finalizing procurement.

Relay Automotive Selection Notes

Select this component when a compact, high-current relay is needed for automotive or general-purpose DC applications requiring a normally open state. The 30A rating supports significant loads, while the 12VDC coil ensures compatibility with standard vehicle electrical systems. Consider the physical dimensions and mounting style to ensure fit within the enclosure. Evaluate thermal management requirements if operating near the upper limits of the specified temperature range.

Relay Automotive Part Context

This part belongs to the CIT Relay and Switch A6 series, which focuses on automotive-grade relays certified to Micro 280 ISO standards. The series offers various contact configurations and coil voltages to address diverse switching needs. The A61AS variant specifically provides the SPST-NO configuration, distinguishing it from SPDT options within the same family. These relays are engineered for reliability in harsh environments typical of automotive and outdoor equipment usage.

Relay Automotive Replacement Considerations

Direct substitutes within the same series include the A61CS12VDC.9, though it features a SPDT contact arrangement rather than SPST-NO. Other compatible parts may exist within the broader A6 catalog, but verification of contact form, coil voltage, and mechanical dimensions is essential to ensure functional equivalence without circuit modification.
