Matsushita Electric Works has a new relay for automotive applications.
Matsushita Electric Works has a new relay for automotive applications.
The CV relay is a low profile version of the Micro-ISO industry standard device and measures just 15.7mm high compared to the standard Micro-ISO device that measures 22mm high.
Other developments to the device include the reduction of audible switching noise level by a further 10dB compared to conventional Micro-ISO relays, operating life to 100k operations electrical at rated load and 1 million operations mechanical.
Typical applications for this new relay include fan heater controls, wiper motors, cruise control, horn and lighting systems.
Furthermore, the CV relay is fully IP67 sealed making it suitable for automated washing processes and harsh environmental applications.
Temperature operating characteristics are -40 to +85C.
The CV is rated at 20A and is available in 1 Form A and 1 Form C contact arrangements.
Both devices have a footprint of 22.5 x 15mm.
The CV relay is available in three terminal configurations: Micro-ISO, Micro-280 and Micro-280 PCB.
Coil suppression is also catered for in the form of a resistor or diode option.
Currently the relay is available in a 12V coil type but a 24V coil version will be available in the future.
