Reduced Flange Jam Nut Receptacles
Description:
The MIL-DTL-38999 Series III style connector features a reduced flange design that saves space, weight, and reduces your footprint when used in PCB applications.
More connectors are able to be fit on a box or board due to the reduced flange having a smaller diameter than a standard jam nut receptacle. The use of a spanner nut can make assembly easier than standard jam nut connectors by using a typical spanner wrench. Even with the reduced footprint, an o-ring remains present to allow for proper panel-to-connector sealing.
Features & Benefits:
- Provides space savings inside the box or on the panel
- Provides direct and indirect weight savings
- 30% lighter than standard 38999/24 (w/o stand-offs)
- Derived from MIL-DTL-38999 Series III Jam Nut
- Available in standard & stand-off varieties
- Mates with standard MIL-DTL-38999 Series III plugs & caps
- Available in crimp or PC tail
- Available in aluminum or stainless steel shells with all standard Amphenol plating options
