Billed as the smallest in its market class, Matsushita's automotive CJ relay has been designed to meet the demands of the increasing use of technology in vehicles and therefore the necessity to reduce the size and weight of electronic components in automotive applications. Occupying two thirds the space and volume of the previous configuration where two independent relay devices were used, the CJ relay has been specifically designed for any applications that require forward and reverse control circuits for DC motors, such as electric windows, central locking, slide door closers and electric mirrors, sunroofs and seats. To provide design engineers with an ideal solution to adhere to the size and volume requirements in modern automotive designs and applications, the 8-pin CJ relay measures just 13.7 x 12.2 x 13.55mm and weighs 6.5g.

These measures make the device ideal for the decentralised control modules, often found inside doors and the head lining, local to the device it controls.

Although the CJ relay is smaller than other twin type relays, it is rated up to 20A/14V DC and is capable of carrying 30A/14V DC.

Moreover, it has a motor lock capability of 25A/14V DC for 100,000 operations as well as a brake load on the normally closed contacts of 20A/14V DC for 200,000 operations.

The relay is available in two coil sensitivities of 640 and 800mW and as with all Matsushita PCB mount relays, the CJ series is presented in a fully sealed IP67 package.
