A61AS24VDC.9R

Relay Automotive Overview

The A61AS24VDC.9R is an automotive relay manufactured by CIT Relay and Switch, designed for through-hole mounting with a PC pin termination style. It features a single-pole single-throw normally open (SPST-NO) contact configuration, also known as 1 Form A. The coil operates at 24VDC with a resistance of 960 Ohms and draws 25 mA. The contacts are rated for 30A switching current and can handle up to 380VAC or 110VDC maximum switching voltage. The unit includes a built-in resistor and is sealed. It functions within a temperature range of -40°C to 85°C and has an operate time of 5 ms and a release time of 2 ms.

Relay Automotive Procurement Notes

Verify the specific ordering suffix and package type against official CIT Relay and Switch documentation to ensure compatibility with your board layout. Confirm that the sealed construction and integrated resistor meet your environmental and circuit design requirements. Check RoHS compliance status if restricted substances are a concern for your manufacturing process.

Relay Automotive Selection Notes

Select this model when a 24VDC coil voltage and 30A SPST-NO contact rating are required for automotive or industrial use. Consider the through-hole form factor and sealed design for durability in harsh environments. Ensure the 5 ms operate time fits your system's timing constraints and verify that the 960 Ohm coil resistance matches your driver circuit capabilities.

Relay Automotive Part Context

This component belongs to the CIT Relay and Switch automotive relay series, which focuses on robust switching solutions for vehicle and heavy-duty applications. The series typically offers various contact configurations and coil voltages to suit different electrical loads. The A61AS24VDC.9R specifically targets applications needing high current handling in a compact, sealed package.

Relay Automotive Replacement Considerations

Consult official CIT Relay and Switch cross-reference guides for direct substitutes. Verify that any alternative part maintains the same SPST-NO configuration, 24VDC coil voltage, and 30A contact rating. Ensure mechanical dimensions and pinout compatibility before replacing.
