A61AS12VDC.9R

Relay Automotive Overview

The A61AS12VDC.9R is a non-latching automotive relay manufactured by CIT Relay and Switch, designed for through-hole mounting with PC pin termination. It features an SPST-NO (1 Form A) contact configuration rated for 30A at 75VDC maximum switching voltage. The coil operates on 12VDC with a power consumption of 900mW and resistance of 160 Ohms. Key electrical parameters include a 5ms operate time and 2ms release time. The unit utilizes AgSnO contact material and functions within a temperature range of -40°C to 85°C.

Relay Automotive Feature Summary

• SPST-NO contact arrangement provides single circuit switching capability for automotive loads.
• Through-hole PC pin termination ensures secure board integration.
• AgSnO contact material supports high current switching applications.

Relay Automotive Applications

• Automotive electrical systems
• Lawn care and maintenance equipment
• Marine applications
• Agriculture applications

Relay Automotive Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm coil power and resistance values. Ensure the component meets Micro 280 ISO certification requirements for your application. Confirm RoHS compliance status prior to procurement. Check datasheet specifications for operating voltage tolerances and contact ratings to match system design constraints accurately.

Relay Automotive Selection Notes

Select this model for applications requiring a 12VDC coil drive with a single normally open contact path. The 30A rating suits moderate to high current automotive loads. Consider the through-hole package for mechanical stability. Verify that the 5ms operate time aligns with system timing requirements. Compare against SPDT variants if common contacts are needed.

Relay Automotive Part Context

This component belongs to the A6 Series of automotive relays from CIT Relay and Switch. The series is certified under Micro 280 ISO standards, indicating suitability for harsh automotive environments. The A61AS variant specifically denotes the SPST-NO configuration with a 12VDC coil. This series is widely used in vehicle lighting, motor control, and accessory circuits.

Relay Automotive Replacement Considerations

The A61AS12VDC1.3 is a documented substitute within the same series offering identical SPST-NO functionality and 30A rating. Verify coil power differences between the .9R and 1.3 suffixes during replacement. Ensure physical footprint compatibility for through-hole mounting when swapping parts.
