2 Pack JD2912-1H 12VDC/40A Car Relays for Auto Starters & Switches

The JD2912-1H-12VDC 40A 14VDC Car Relay 4 Pin 12V model is designed to handle versatile applications, such as starter cuts, dome light monitoring, trunk release, polarity shifting, power door lock/actuator management, converting low current to high, and controlling motors/electronics. It's ideal for automotive use in scenarios involving alarms, horns, headlights, and more. The relay can be conveniently integrated with an optional Relay Harness or female Crimp Connectors for seamless installation.

This relay boasts impressive specifications: a contact material of AgSnO12, a 1Z(C)/1H(A) contact form, a 40A rating at 72VDC with a maximum contact resistance of 100mΩ at 6VDC/1A. Its switching capabilities reach up to 40A, with a power capacity of 560W. The relay has an expected lifespan of 100,000 operations at 30 operations per minute electrically and 10,000,000 operations mechanically. The coil operates at a nominal voltage of 12VDC, with a resistance of 80 Ohms at 1.8W, and it can withstand voltages between 6.5 to 8.0VDC during operation and 1.2 to 3.6VDC during mixing release. The maximum applicable voltage is 14VDC.

Featuring a temperature range of -30°C to +80°C, it exhibits robust vibration resistance at 10 to 55Hz with a 1.5mm shock tolerance, and withstands operational extremes of 10g without damage, up to 100g. The relay maintains a humidity resistance of 40% to 85% with an insulation resistance of 100mΩ minimum at 500VDC. Safety standards are met with CCEE certification, ensuring a dielectric strength of 500VAC between open contacts for one minute and 750VAC between the contact and coil.

Each package includes two brand new 40A 4-Pin 12V Vehicle Relays, boasting a mechanical life cycle exceeding 10,000 cycles. This versatile relay is ready to fulfill numerous automotive functions and is a reliable choice for integrating into various systems.
