Onboard Contact: OG-453239-A

SMT grounding contact for engine compartment PCB

Connecting a GND layer of PCB with multiple points on a chassis can be expected to suppress radiation noise
Connectors are prone to static electricity. When the OG is placed near a connector, it creates a ground connection with the chassis to release the static electricity
The spring structure has durability for 10 million vibrations, considering the deflection of PC boards caused by vibration
Sustained conduction is secured because of unique dimple design
Can be used under high temperature at 150ºC
