Assembly for Ck-M2x Series
1. Strip outer jacket of wire 0.300 in.
2. Cut off shield and drain wire (for twisted shielded pair wires only).
3. Strip the insulation of two conductor wires back 0.200 in.
4. Crimp conductor wires into contact sockets. CTC’s CB926-1A crimp tool
makes crimping fast and easy and can lead to significant time savings when
installing a large volume of connector kits. Adjusting the green depth knob
to the desired length allows the depth of the contacts to be set manually to
ensure a crimp at the correct location every time. Suggested depth for the
“M” Series is 0.52 in.
5. Slide backshell and knurled ring onto the cable.
0.300 in.
0.200 in.

6. Attach O-ring to the front of the insert.
7. Using a fine-tipped punch, gently press each contact into the appropriate
position on the insert.
a. Install accelerometer red (+) wire into the insert socket for Pin 1.
b. Install accelerometer black (-) wire into insert socket for Pin 2.
c. Install the remaining pin contacts into the non-used spaces.
8. Slide the knurled ring over the threaded section of the insert until the metal
step inside the ring catches on the plastic lip of the insert.
9. Thread the backshell onto the insert.

8
10. Place the assembled connector body horizontally with the two small epoxy
injection holes level and facing upward.
11. Mix epoxy. Using a syringe, fill the backshell with epoxy through one of the
small injection holes until epoxy begins to seep from the other.
12. Keep the connector in a horizontal position, allowing the epoxy to set and
vent any trapped air, refilling as needed, for approximately six hours.
13. Allow the epoxy to cure for 24 hours at room temperature. Place a piece of
masking tape over the two epoxy holes to prevent leakage and hang the
connector vertically with the insert facing downward. This will ensure epoxy
encapsulates the cable evenly, especially if the cable diameter is smaller
than the backshell opening.

b. Install accelerometer black (-) wire into insert socket for Pin 2.
c. Install accelerometer white (+) wire into the insert socket for Pin 3.
d. Install the remaining pin contacts into the non-used spaces.
8. Slide the knurled ring over the threaded section of the insert until the metal
step inside the ring catches on the plastic lip of the insert.
