Hi-D Jax enclosed 1/4" phone jacks are ideal for panel/chassis and PC board mounting. Unitized molded housing protects springs, provides mechanical and electrical reliability, minimizes leakage and provides low capacity between springs. Mounts on .625" minimum centers in rows or arrays in a single .375" diameter hole.

Formed shoulders on each terminal provide stable stand-off mount. Threaded bushing permits mechanical connection to equipment panel. Mounting hardware is supplied.

Also available is a grounding spur bushing, which allows for positive grounding of the bushing to the chassis. Contact factory for details
