How to assemble the connector
1
Release the tabs on the 
connector hood and pull out 
the connector in the direction 
of the arrow.
(The LV Series does not have 
the connector hood)
2
Hold the IDC connector so that 
the back side (side where the 
wires can be seen) is facing 
forward. Push the upper tab in 
the direction of arrow (1) and 
then open the back side in the 
direction of arrow (2).
3
Cut the cables to the appropriate length, and manipulate the end of the 
cables as shown in the figure below.
• Peel back the insulation 20 mm from the end.
• Cut the copper shielded wire at its root. (Cut the white string likewise.)
• Twist the silver shielded wire about five times so it does not ravel, and 
bend it 90° to the side.
4
Insert the core wires to the very end of the connector hole of the 
matching sticker color, and bend the silver shielded wires while pulling 
each one of them along the grooves in the direction of the arrow.
5
Close the connector to crimp with a tool such as a parallel plier 
(commercially available).
6
Close the upper tab to lock the cables, and then trim off the wires 
sticking out of the connector by using a nipper or the like.
7
Firmly insert the connector 
into the connector hood.
(The LV Series does not 
have the connector hood.)
It indicates a situation which, if not avoided, could result in 
product damage as well as property damage.
It indicates tips for better understanding or useful information.
When the cable length of the sensor head is changed, be sure 
to connect the amplifier to check that it operates correctly.

• lFor re-installation of the connector, limit it to 2 times. If it
is done more than 2 times, use the special OP-87305.
• As opposed to the OP-87305 or the
OP-66850, it is not necessary to use the 
connector crimping tool.
If it is used in error, it may cause a 
break in the wiring so do not use the 
connector crimping tool.
The OP-87305 and the OP-66850 can distinguished in the fashions 
below.
