A61AS24VDC1.3D

Relay Automotive Overview

The A61AS24VDC1.3D is a micro automotive relay from the CIT Relay and Switch A6 series, designed for through-hole mounting with PC pin termination. It features an SPST-NO (1 Form A) contact configuration rated for 30A at 14VDC and 75VDC maximum switching voltage. The coil operates on 24VDC with a resistance of 436 Ohms and consumes 1.3W of power. Key electrical parameters include a coil current of approximately 55 mA, a pull-in voltage of 16.8 VDC, and a drop-out voltage of 2.4 VDC. Mechanical performance specifies a working time of 5 ms and a release time of 2 ms. The unit utilizes Silver Tin Oxide (AgSnO) contacts and functions within a temperature range of -40°C to 85°C.

Relay Automotive Procurement Notes

Verify the specific suffix 'D' against official CIT documentation to confirm if it denotes a distinct variant or packaging difference compared to the base A61AS24VDC1.3 model. Ensure compatibility with PCB layouts requiring PC pin termination. Confirm RoHS3 compliance status for the specific batch. Cross-reference the 30A rating with actual circuit loads to prevent derating issues in high-current automotive environments.

Relay Automotive Selection Notes

Select this component for automotive circuits requiring a single normally open contact with high current capacity. The 24VDC coil voltage suits heavy-duty vehicle systems. Consider the 5 ms operating speed for general switching rather than high-frequency applications. The through-hole package offers robust mechanical stability compared to surface-mount alternatives. Verify space constraints for the relay footprint before integration into control modules.
