2.3 EMC Prevention
If EMC/EMI prevention is required, use a conductive treatment such as non-chromate for the
surface treatment of the panel.
For reliable grounding on the plug side, connect the ground wire to the unit with a ring
terminal, or connect the braided shield to the clamp metal.
<Connect the ground wire to the unit with a ring terminal> <Connect braided shield to metal clamp>
If you want to protect loose wires from EMC, use commercial EMC protection materials such as
braided shields or shielding gaskets.

2.5 Plug Selection
The appropriate plug selection depends on the type of cable to be used and the cabling direction.
Please check the following and select the plug accordingly.

TJ50A-41S-D-CV
Cable Tie
TJ50A-41S-U-CV1
TJ50A-41S-D-CV1
<<Metal Clamp Design>>
CV Clamp metal : Fits inside the unit
CV1 Clamp metal : Protrudes from unit
Using cable ties can reduce cable shaking (see Section 3.4)
Since the unit is exposed to the outside, be careful not to interfere with
other products. The width of the CV is 79.3 mm and the width of CV1 is 93 mm.
When using a cabtire cable, we recommend CV1 which can be fixed at two points.
This is because it is difficult to bend the cable when it is moved, so the cable may rotate
around the center of the clamp if there is only one fixing point and apply a load to the
crimping part.
<<One Fixing Point on CV>> <<Two Fixing Points on CV1>>
Secured at Two Points with
Both Clamp and Cable Tie
Clamp Secures Cable
at One Point
If you move the cable,
the crimping part may move in
the opposite direction.
Even moving the cable,
the crimping part doesn’t move
due to cable tie.

In addition, the metal clamp height differs from stated dimensions and the number of cables that
can be stored is different.
Refer to the table below. (It depends on the cable you use, so please check the actual product.)

The tensile strength of the cable may be under 98 N depending on the diameter of the cable used,
the material and composition of the sheath, the number of pins, etc.
Therefore, adjust the cable diameter with a shrink tube or copper tape.
Example: When fixing 10 cables with a wire size of 26 AWG and outer diameter of insulator Φ1.3,
put the cable for use, cutting cables and other intervening materials into the shrink tube and
make the overall thickness Φ12.2 to 13.0.
<<Cable Direction>>
Depending on the plug, the cabling direction is either upward or downward.
One plug does not support both directions, so please be careful when choosing the connector.
(The VME standard determines the position of the contact number, so be careful when conforming
to the standard.)

3.2 Plug Installation Procedures
<<Plug>>
1. Insert the crimped female contact in the direction of the arrow until it reaches the inside
of the housing. The contact lance is on the side without the housing polarity mark (Δ).
2. Insert the S housing into Unit A in the direction where the distinction mark is visible.
(It is designed so insertion to the other side is not possible.)
3. Attach the metal clamp to Unit A and tighten the cable. Make sure it is in the right position
with the slide buttons as shown, then cover Unit B from above, and screw it in three places.
(Recommended tightening torque 0.315 ±0.06 N·m)
When using a metal clamp for ground connection, wrap a copper tape around the braid shield
And secure that part with a metal clamp. Depending on the type and number of wires, if the
cmetal clamp and the copper tape do not contact with the product, adjust the thickness with
plastic tape or copper tape.
For ground connection using a commercially available ring terminal, after crimping the ring
terminal, secure it to the ground wire with a M3 screw.
(Recommended tightening torque 0.315 ±0.06 N·m)
4. Insert the key(sold separately) into the plug body
and tighten the screw.

3.3 Crimp Contact Repair Method
Use the PQ50S/RE-MD tool shown below for contact extraction.
Insert the tool into the area indicated by the white arrow,
and remove it by lowering the contact lance
(In-line type crimp contacts can also be removed in the same way.)
Insert the tool until it reaches the back and gently pull the cable.
If it does not come off even if you pull it lightly, the lance is not released,
so please try again.
If you pull it forcefully, the lance hook part of the housing will be damaged.
Once pulled out, the contact lance lowers, and it may not be hooked even if it is inserted into
the housing.
When reusing, raise the lance to the position shown in the figure below with a pin.
(Lance can only be modified once.)
The housing lance hook where the contact was once pulled out may be chipped off.
If you want to use the contact after inserting it again, please check Section 4.2 "Contact
Assembly Confirmation” and check whether the contact is secured.
In addition, when the contact is removed without using a tool, the lance hook may be shaved down
significantly. Please change the case for a new one.

3.4 Cable Clamping Method
To accommodate a variety of cables, a large space for clamping the cables is needed.
Therefore, the cable may not be secured depending on the cable diameter,
sheath material and composition, the number of pins, etc. Adjust the thickness
with a shrink tube or copper tape so that the cable can be secured .
※Recommended cable tensile strength: 98 N
The metal clamp of CV1 can be reinforced with a cable tie as indicated below.
When a load is applied to the cable, optionally fix the cable to the metal clamp with a cable
tie. The cable tie is not provided, so please prepare it.
Depending on the position of the coupling part of the cable tie, it may be difficult to grip
the connector body. In that case, fix it so that the coupling part of the cable tie contacts the
ridged part of the metal clamp.
In addition, please secure the cable to the wall or floor in an environment where vibration is
applied. If the cable is fixed within 25 cm from the cable clamp and there is no slack,
the connector cannot be inserted or removed, so please fix it around 30 cm from the clamp.
Please fix the cable around
30 cm from the cable clamp

3.5 Mating and Locking Method
When mating the plug with the receptacle, insert the plug straight until it locks.
If you accidentally hit the corner of the plug against the receptacle’s contact,
you may deform the contact.
To prevent accidental mating, there is a slide button for locking the cover case
of the plug. After locking, the unlock button can be fixed by operating the slide button
as shown below.
The locking state can be checked at a glance with the red color under the slide unlock.
(You cannot use the unlock button when the red color is not visible.)
By returning the slide button, the unlock button can be operated.
