Installation Guide - Position Transducers
1. Grip and center the loop sleeve lengthwise in the crimp tool using
the top hole (hole farthest from the crimp tool handles; see Figure 9.
2. Thread displacement cable through loop sleeve to form a loop until
desired crimping location is reached.
3. Squeeze crimp tool firmly until the tool jaws fully mate. Rotate the
loop sleeve 90° and squeeze crimp tool firmly. Minor crimp
imperfections are to be expected.
4. Pull on the displacement cable loop while holding the loop sleeve
and ensure that the crimped loop sleeve is secure.

Crimping the Copper Sleeve Using Electrical Connector Crimping Tools and Non-Specialized Pliers
To crimp the copper sleeve to the displacement cable, loop the displacement cable through the copper sleeve, through
the swivel or pull ring, and then back through the copper sleeve. Crimp the copper sleeve using a 4-pronged electrical
connector crimping tool or equivalent.
Firstmark Controls does not provide the crimping tools for crimping the
copper sleeve to the displacement cable. There are numerous suppliers of
these types of products worldwide. One company that produces these
products is Astro Tool Corporation (
crimp tool will work. For crimping the copper sleeve to the looped (double
thickness) 0.018-inch (0.4572 mm) diameter displacement cable, use a
0.041-inch (1.0414-mm) gage pin to set the crimping diameter on the crimp
tool and then do a pull test. For the looped (double thickness) 0.027-inch
(0.6858 mm) diameter displacement cable, use a 0.049-inch (1.2446-mm)
gage pin. You may also purchase an appropriate calibrating tool from Astro
Tool Corporation. An acceptable but aesthetically less pleasing way to
crimp to the copper sleeve is to use simple pliers. See Figure 10.

Use of the Thimble and Creating Leaders
The thimbles provided in the 160001-01 installation kit can be used
with the loop sleeve or copper sleeve to produce very rugged
displacement cable terminations or leaders for attachment of the
position transducer to the application. See Figure 11.

cable guide, remember these tips:
●
Do Not Continuously Rotate - Do not continuously rotate the transducer nor the RoundAbout

cable guide about
the displacement cable's length axis. Doing so will wind up the displacement cable until a kink forms.
