IDC, Metal Shell – Panel Mount
Introduction | Part Numbers | Dimensions
“Panel mount” products are connectors without hoods. They are typically used to provide signal I/O from a system panel or cabinet, where strain relief to a cable jacket is not required.
- Standard versions have .103″ mounting holes (sockets have .103″ with float bushings) for use with #3 hardware, or with .185″ mounting holes for use with #8 hardware.
- Bail latching sockets are available, as are bail latching plugs. While the plugs would not be panel-mounted, they are available for premold/solder overmolding applications.
Features
Patented contact terminates Discrete Wire (loose or jacketed cable) without stripping or soldering. Solid wire versions available.
- Metal shell provides grounding and shielding capability.
- Available in 50 position plug and socket.
- Designed for panel mount, 180° (Top-Entry), or 90° (Standard) / 270° (Reverse) End-Entry cable applications.
- Overmold kits available
- All Plugs lock with InstaLatch passive latch feature for automatic latching. Full range of application tooling available for termination, unlatching, etc.
- UL Recognized – Files E170218 (UL1977), E130965 (UL1863).
- CSA Approved – File LR31996-7.
