Board-to-wire
Board-to-wire
Features
- Lower profile The height from PC board is lower than ZRO connector.
- Improvement of Operability The lever is adopted to decrease the connector mating force. The fixing part to PC board is lightly press-fitted boss configuration in consideration of the workability when assembling.
- Sealed Mat seal is adopted for improving the workability of wire seal part.
- Durability Heat resistant specification corresponding up to 125˳.
- Variation If the optional harness cover is used, the harness can be taken out from the side.
