Figure B.2 – Pinout for Power and Communication Signals
To create custom cables proper connector crimping tools are necessary. The
SmartSensor Matrix cable connector uses a MILC-C-26482 Series 1 connector,
crimping contacts, and a watertight back shell. A kit with these parts can be
ordered directly from Wavetronix.
Size 20 contacts are used to accommodate the 20 and 22 gauge wires in the
cable. (The SmartSensor cable’s red and black wires provide a 20 AWG wire pair.
The other pairs on the SmartSensor cable are 22 AWG and are normally used for
communication.)
To create a custom cable (see Figure B.3):
1. Slide the strain relief, follower, grommet, and back shell over the cable.
2. Strip the cable jacket and shielding back about 1.5 inches.
3. Strip each of the 7 SmartSensor cable wires back about 0.25 inches.
4. Insert the wires into the contacts and verify the wire is visible through the
contact inspection hole.
5. Crimp the wires by following the crimping tool instructions. Daniels
Manufacturing Company provides professional grade crimping tools and
detailed instructions on crimping. Wavetronix recommends the DMF AF8
M22520/1-01 or equivalent tool for crimping.
6. Manually press the contacts into the backside of the connector plug using
the pinout information in Figure B.2.
7. Use a DMC DAK20 or equivalent insertion tool to fully seat the contact into
the connector plug. Check the mating face of the connector to ensure that
