A41CS24VDC

Relay Automotive Overview

The A41CS24VDC is a sealed automotive relay from the CIT Relay and Switch A4 series, designed for through-hole mounting. It features a single pole double throw (SPDT) contact configuration with a 20 A rated current capacity. The coil operates at 24 VDC with a resistance of 576 Ohms and draws 41.7 mA. Maximum switching ratings are 380 VAC and 75 VDC. Contact materials utilize silver tin oxide (AgSnO) to ensure durability in automotive environments. The unit functions within a temperature range of -40°C to 85°C.

Relay Automotive Feature Summary

• Sealed construction suitable for harsh automotive conditions
• Silver tin oxide contacts for high current handling
• Through-hole PC pin termination for board integration

Relay Automotive Applications

• Automotive electrical circuit protection
• Vehicle lighting control systems
• High-current accessory power distribution

Relay Automotive Procurement Notes

Verify the specific suffix 'CS' confirms the silver tin oxide contact material and automotive rating. Ensure the through-hole package matches the target PCB footprint. Confirm RoHS compliance status aligns with project requirements. Cross-reference the 24 VDC coil voltage against the system supply to prevent under-driving or overheating issues during procurement validation.

Relay Automotive Selection Notes

Select this component when a robust, high-current automotive relay is required for permanent installation. The sealed design protects against moisture and vibration common in vehicle chassis applications. Consider the 20 A load capacity and SPDT configuration for switching heavy loads like motors or lights. Verify that the 24 VDC coil voltage matches the vehicle's electrical architecture before finalizing the design.

Relay Automotive Part Context

This part belongs to the CIT A4 series of automotive relays, which are engineered for reliability in demanding vehicular environments. The series offers various coil voltages and contact configurations to support diverse automotive electrical needs. The A41CS24VDC specifically addresses applications requiring high current switching with durable silver tin oxide contacts.

Relay Automotive Replacement Considerations

Direct substitutes include other CIT A4 series relays with identical coil voltage and contact ratings. Check for equivalent automotive-grade seals and terminal styles. Verify that any replacement maintains the same SPDT configuration and 20 A current capacity for safe operation.
