A61CS24VDC.9

Relay Automotive Overview

The A61CS24VDC.9 is a micro automotive relay manufactured by CIT Relay and Switch, designed for through-hole mounting with PC pin termination. It features a single Form C (SPDT) contact arrangement rated for 30 Amperes at a maximum switching voltage of 75 VDC. The coil operates on 24 VDC with a resistance of 640 Ohms and consumes 900 mW. Certified to Micro 280 ISO standards, the unit functions within a temperature range of -40°C to 85°C. Key electrical parameters include an operating time of 5 ms and a release time of 2 ms.

Relay Automotive Feature Summary

• Compliant with Micro 280 ISO automotive standards for reliable operation in vehicle environments.
• Utilizes silver tin oxide (AgSnO) contact material to ensure durability under high current loads.
• Offers a compact micro form factor suitable for space-constrained electronic assemblies.

Relay Automotive Applications

• Automotive lighting control systems
• Vehicle accessory power distribution
• General purpose switching in automotive electronics

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm terminal style and packaging configuration. Ensure that the required coil voltage and contact rating align with the target circuit design before procurement. Cross-reference the component marking with the datasheet to authenticate the source and prevent counterfeit substitution during acquisition.

Relay Automotive Selection Notes

Select this component when a robust 30A switching capability is required within a micro-sized footprint for automotive applications. The 24VDC coil specification suits standard vehicle electrical architectures. Consider the SPDT configuration for circuits requiring a common terminal with separate normally open and closed paths. Verify thermal management requirements given the operational temperature range limits.

Relay Automotive Part Context

This part belongs to the A61 series of micro automotive relays from CIT Relay and Switch. The series is characterized by its compliance with Micro 280 ISO specifications, ensuring suitability for harsh automotive environments. The A61CS variant specifically denotes the Single Pole Double Throw contact configuration within this standardized product line.

Relay Automotive Replacement Considerations

Direct substitutes must match the 24VDC coil voltage, 30A current rating, SPDT contact form, and Micro 280 ISO mechanical dimensions. Verify that alternative components maintain the same AgSnO contact material and through-hole PC pin termination style to ensure compatibility with existing PCB layouts.
