WIRELESS TRANSMISSION HIGH CURRENT CONNECTORS















PSI High Current + VL High Current are the connectors highlighted this month.

These connectors implanted for the energy management of our household appliances are for energy saving purposes.
Indeed, they aim to regulate and measure our consumption (renewable energies) and are present in devices powered by electricity while being connected to the mains such as:
- Heat pumps,
- Pellet stoves,
- Temperature controllers,
- Air conditioners,
- Air purifiers,
- Household robots & appliances.

These series, by their peculiarities, are presented as alternatives to the VH series.

Their characteristics are as follows:


PSI WTB CONNECTOR - 8 mm PITCH
Low insertion force type contact is adopted and provides excellent operability.
This connector has the secure locking device that has the mechanism to prevent the inverse insertion.
The connector suitable for the large electric current was realized by using highly conducting material.
By adopting key shape and multi colors of housing, prevention function of is-mating with conventional PSI connector is considered.
> Secure-lock device
> Mis-mating prevention mechanism by keying
> Finger friendly design
> Large electric current was realized
