A2H1ASP24VDC1.6D

Relay Automotive Overview

The A2H1ASP24VDC1.6D is an automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a rated current capacity of 40 amperes. The device operates with a 24-volt DC coil voltage and utilizes through-hole mounting for secure integration into circuit boards. Key electrical specifications include a maximum switching voltage of 75 volts DC and a non-latching coil type. The relay is constructed with silver tin oxide contacts to ensure durability and low resistance during operation.

Relay Automotive Feature Summary

Relay Automotive Procurement Notes

Verify the specific ordering suffix to confirm the exact pin configuration and terminal style required for your assembly. Ensure the coil voltage matches the system supply precisely to avoid actuation failure. Cross-reference the datasheet for thermal derating curves if operating near maximum current limits. Confirm that the through-hole footprint aligns with the PCB layout guidelines provided in the official documentation before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a robust, sealed relay is needed for high-current automotive applications requiring 40A capacity. The SPST-NO configuration is suitable for simple on/off control of loads such as lights or motors. Consider the through-hole mounting requirement versus surface mount alternatives if space constraints exist. Verify that the 24VDC coil voltage is compatible with the vehicle's electrical architecture to ensure reliable operation under varying load conditions.

Relay Automotive Part Context

This part belongs to the A2 series of automotive relays from CIT Relay and Switch, which are characterized by their compact size and high switching capacity. The series is widely used in automotive industries for controlling various electrical accessories. The A2H1ASP24VDC1.6D specifically denotes the 24VDC coil variant with a standard actuator height, fitting within the broader family of sealed automotive relays designed for harsh environments.

Relay Automotive Replacement Considerations

Compatible substitutes include other 40A SPST-NO automotive relays with 24VDC coils and through-hole mounting. Ensure any replacement maintains the same contact material and sealing rating to preserve performance integrity in automotive applications.
