Crimp Tool for LMR-600, RG-217/U and other 0.590 Coax Type Connectors
Used to install cable end connectors for all LMR-600, RG-217, RG-217/U, and other .590 coax connectors that are assembled by the Crimp-On interface type.
Installation Guide Example of the 7305-N-600 Type N male connector:
We will begin by installing the Type N male connector on a piece of LMR-600. This process is the same for all the other types of cable with an outer jacket OD of 0.590. These connectors fit on a wide range of coax types including, but not limited to: RG-217/U, LMR-600, and other 0.59 inch OD coax.
Identify all connector parts (3 parts):
Each connector consists of one body assembly (plug), one rear ferrule (crimp sleeve), and one center pin (plug contact).
First cut your cable to the desired length and then strip the black jacket back approximately 0.55 inches. When the jacket is stripped cut the braid/foil back 0.225 inches from the fresh cut end. Finally, cut back the dielectric 0.16 inches from the fresh end down to the center conductor. The braid needs to be cut back further than the dielectric to insure that none of the braid or foil is touching the center conductor which could cause a short.
Note: Do not nick the braid, dielectric, and center conductor if at all possible. Tinning of the center conductor is not necessary if contact is to be crimped. For solder method, tin the center conductor if the center is stranded. twist the center conductor very tightly prior to tinning.
Installation Method Selection:
Slide the outer ferrule onto the coax as shown below. Flare the braid slightly to allow insertion of the connector main body. Important: Do not comb out braid.
Place the center contact on the center conductor of the coax so that it butts against the cable dielectric. The center conductor should be visible through the solder / inspection hole of the contact. Solder contact in place as follows:
Crimp-on the Ferrule
Use the 7505-HANDLE-600 crimp handle for the ferrule. (DO NOT CRIMP / CRUSH THE CENTER PIN)
Solder the Pin
Make sure the solder hole is facing up. Touch the soldering iron to the underside of the center pin directly under the solder hole. Touch the solder to the center conductor through the solder hole on the center pin. Allow the heat from the metal to melt the solder so that it wicks into the center pin. Once the solder melts it only takes a tiny amount of solder to make the connection. Do not allow the solder to pool over the solder hole. The outside of the center pin should be free of obstructions for insertion. Do not over heat the center pin which could cause swelling of the dielectric of the coax.
Main Body Install:
Install the cable assembly with the center pin already affixed, into the main body of the connector. The knurled portion of the main body slides under the braid of the coax. Push the cable assembly into the main body until the center pin snaps into place in the dielectric of the connector.
Slide the ferrule (placed on the coax at the beginning of Step 2) over the braid and completely up against the connector body. Using the 0.590 hex of the 7505-HANDLE-600 crimp handle, crimp the ferrule at the location shown in the picture below (on the ferrule, but right up against the main body of the connector).
When this is completed, as a final test, you should always check resistance from the center pin to the body with an ohmmeter in a low resistance scale. After verifying that there are no braid – to – center pin shorts on the other end of the coaxial cable, you should see infinite resistance (open).
