Crimp Tool for Signal Connectors M 23 / M 16
Crimp Tool
Adjustment of Crimp Depth
Crimp depth can be adjusted as follows:
Turn the adjusting screw clockwise for reducing the crimp depth and counter-clock-
wise for increasing the crimp depth.
Adjustment Increments:
- 1 space on the adjusting screw = adjustment by 0.01 mm
- 1 full rotation of adjusting screw = adjustment by 0.2 mm (indication on the screw
as well as on the rough scale)
- 5 rotations of the adjusting screw =adjustment by 1 mm (indication on the scale)
Control of Crimp Depth
Crimp tool adjustment is done at the factory, but with frequent use, periodic calibra-
tion is recommended to insure accuracy. This is easily accomplished with a 1.0 mm Ø
wire gauge as follows.
A crimp depth of 1.0 mm is set by means of the adjusting screw (scale mark at „1“,
screw mark at „0“ as shown in the fig. above) and the tool in the closed position.
After insertion of the gauge, there must be just enough space for moving the gauge
inside the entry hole. If the opening is too small or too large to exactly match the
gauge, the deviation (+/-) can be checked by the precision setting of the screw.
Please contact the factory in case the deviation exceeds the tolerances specified by
the contract manufacturer.
Maintenance and Repair
Keep the tool clean and properly stored when not in service. All pivot points need to
be oiled regularly and the spring clips securing the bolts have to always be in place.
For repair please send the tool back to the factory.
