Brief Description

We have developed Elbow style, swivel bulkhead connector, with 90 Degree BNC Male.

The new design allows installing the bulkhead connector in available - desirable direction on your housing. Elbow shape (90 degrees) of the connector keeps the external cable horizontally, instead of the standard vertical style of the connection.
