I rescued these from unwanted signal leads about 30 years ago in case they might come in for caravan leads, etc, but they never did so they have to go.
TYPE 1 (5 connectors on left of photos)
Unbranded free (cable-mounted) alloy connectors as follows:
2 x plugs (pin contacts) with 90 degree outlets
2 x sockets (socket contacts) with 90 degree outlets
1 x socket (socket contacts) with straight outlet.
The plugs and sockets do not make mating pairs - see photos. The different orientations prevent wrong connection of cables to panel connectors.
These look similar to some MIL spec connectors.
They are screw-type mating (not bayonet) and have the following measured dimensions
Max diameter over locking collar = 28.8 mm
Outside diameter of body (not including locating dogs) = 15.7 mm
Pin diameter - 1.63 mm
TYPE 2 (2 connectors on right of photos)
Amphenol free (cable-mounted) plugs, MS3106A - 14S2P, conforming to MIL-C-5015, complete with cable clamps. They are 4-way (pins) as shown.
These are currently about £20 + VAT each from RS, etc.
If you have any queries, please ask.
Price is for all seven connectors to collect or hand over local to Leeds.
Packing and postage (Royal Mail 2nd class, UK) will be £3 extra.
Cash, cheque or bank transfer only, thanks.
