How To: Pass-Through Crimp and Termination Tool

How To: Pass Through Crimp and Termination Tool

Written by Don Schultz, trueCABLE Technical Sales Representative & Fluke Networks Certified Technician

 

Our Pass-Through Crimp and Termination Tool - V1 performs multiple functions simultaneously. Very little maintenance is required to keep your tool in top functioning condition. It will provide you many years of service.

Top Choice for Ethernet Projects

  • Capable of crimping and terminating any RJ45 plug (except AMP style or plugs that do not possess a strain latch)
  • Automatically cuts off conductor excess from pass-through style plugs
  • TIA 568A and TIA 568B color sequences printed on the side of the tool
  • Cuts and strips Ethernet cable, on a backup basis, if you forget to bring along your trueCABLE Cable Stripping & Cutting Tool
  • Gunlock sliding lock keeps the tool closed when not in use, and is easy to operate with one hand
  • Bright green accents so it does not disappear into your tool bag
  • Strong and long-life internal components
  • Replaceable cutting blade
  • Rust-resistant steel oxide construction
  • Forever Warranty

(1) It goes right here. The strain-latch presser bar passes through the rectangle cut out and then (2) Crimps the cable jacket into place so it does not pull out.

Note: 

Some RJ45 connectors don’t have the cut-out or plastic, triangle piece. This is why our V1 tool requires RJ45 plugs with a strain latch. If the plug does not have this, it will smash the plug and ruin your termination (possibly your day too).

Due to lever opening limitations, the maximum cable jacket thickness you can cut is about 7.30mm.

After cutting, you can also strip the cable jacket….but….

Note: 

When stripping an Ethernet cable jacket this way, the cut depth to achieve a good score on the cable jacket is completely dependent on the pressure applied to the lever handle. While it will work, this method should be considered a back-up option (eg. you forgot your cut and strip tool). 

 

Basic Maintenance

After each use:

Wipe down the exterior metal surfaces with a small amount of high-quality preservative oil, or a silicon “gun and reel” cloth.

Twice a year or quarterly for heavy usage:

Oil the indicated lubrication points. Use only one drop of oil at each indicated point. An extremely high-quality firearms grade PTFE bearing lubrication and preservation oil is recommended.

 

Lubrication point at the handle. Second linkage lubrication point.

Lubrication point at the handle. Use one drop of oil only on the pin, on either side of the linkage. A needle oiler is a great help with this lubrication point. Second linkage lubrication point. One drop of oil on either side of the link, on the pin itself, is all that is necessary.

Flush Cut Blade Adjustment

The flush cut blade that removes conductors from the nose of the RJ45 plug is replaceable.    First,  lock the tool and use a Phillips screwdriver to back out the screw. Now, unlock the tool to lower the presser bar and termination teeth.  Using a rod or other thin rigid tool inserted from the opposite side, tap until the blade assembly is dislodged from the locator roll pin found below the screw.  Once the blade assembly has been pushed off, put a fresh blade assembly onto the locator roll pin.  Replace the screw and tighten down firmly.

Unlock the tool so the termination teeth and presser bar are lowered.  The blade must be tapped/pushed off from this side, using a thin & rigid rod.This exposes the locator roll pin.   Discard the old blade assembly.

Note: 

Do not dispose of the old blade carelessly. A “dull” blade is still more than sharp enough to cut you or others. Place the blade onto the tacky side surface of a piece of duct or heavy electrical tape and wrap several times so the edge is not exposed. Dispose of carefully.

 

Replace the blade assembly with the new one.  Insert and firmly tighten screw.

Note: 

If you notice that the flush cut blade is shaving off the actual plastic of the plug, try reducing the pressure used to insert and hold the plug/cable into the crimp cavity during the crimp operation.  Light pressure is sufficient, and you may stop holding the cable after the strain latch presser bar begins passing into the rear of the RJ45 plug during the termination process.  The strain latch presser bar will “lock” the plug into the correct position during the procedure.

Cut and Strip Blade Replacement

The cutting blade at the rear of the tool is replaceable. Be careful during replacement, this blade is razor-sharp. A small Phillips screwdriver is required.

  • Disengage the lock to release the lever
  • Unscrew the screw
  • Carefully remove the worn blade
  • Replace with the new blade and screw back down. The blade should be replaced into the exact position it was removed.

Alert! Do not dispose of the old blade carelessly. A “dull” blade is still more than sharp enough to cut you or others. Place the blade onto the tacky side surface of a piece of duct or heavy electrical tape and wrap several times so the edge is not exposed. Dispose of carefully.

There is our Pass-Through Crimp and Termination Tool - V1 in a nutshell. Treat this tool well, and it will serve you for years to come!
