A3K1CSQ24VDC1.6R

Relay Automotive Overview

The A3K1CSQ24VDC1.6R is a non-latching relay from the CIT A3K series, designed for high-current switching applications. It features a 24VDC coil voltage with a maximum of 31.2VDC and operates at 66.7 mA. The unit utilizes an SPDT (Form C) contact arrangement capable of handling up to 80A. Key technical attributes include magnetic blowout technology and an integrated resistor within the sealed housing. The component supports both PCB pin and quick connect mounting options, ensuring compatibility with various industrial and automotive circuit configurations requiring robust electrical isolation and high load capacity.

Relay Automotive Feature Summary

• SPDT contact configuration providing single pole double throw switching capability
• Integrated magnetic blowout mechanism for enhanced arc suppression
• Sealed construction with internal resistor for reliable operation
• Supports multiple mounting methods including PCB pins and quick connects

Relay Automotive Applications

• Automotive lighting control systems
• Industrial machinery power distribution
• Lamp accessory actuation circuits
• High-current DC load switching

Relay Automotive Procurement Notes

Verify the specific suffix 'R' indicates the inclusion of the internal resistor as documented in official CIT specifications. Confirm that the SPDT contact form aligns with the target circuit design requirements. Ensure the 24VDC coil voltage matches the available control supply. Check for RoHS compliance status if required by the end-use environment. Validate that the 80A current rating exceeds the maximum expected load current under all operating conditions.

Relay Automotive Selection Notes

Select this model when a non-latching relay with high current capacity is required for DC applications. The SPDT configuration allows for complex switching logic compared to SPST variants. Consider the sealed design for environments where moisture or dust protection is necessary. The availability of quick connect terminals may simplify assembly processes compared to standard PCB-only mounts. Evaluate the coil resistance and current draw against the controlling microcontroller or driver capabilities.

Relay Automotive Part Context

This component belongs to the CIT A3K series of Maxi relays, which are characterized by large switching capacities and compact physical dimensions. The series is certified under QS-9000 and ISO-9002 standards, indicating adherence to strict manufacturing quality controls. These relays are engineered for durability in demanding automotive and industrial sectors, offering a balance between high performance and small footprint.

Relay Automotive Replacement Considerations

Direct substitutes within the same series include the A3K1CSQ24VDC1.6, which shares identical coil and contact specifications but may differ in terminal configuration or packaging. Verify that any replacement maintains the SPDT contact form and 24VDC coil voltage. Ensure the substitute part also includes the magnetic blowout feature and sealed construction to preserve performance characteristics.
