OMEGA® Retractable Sensor Cable 
is color coded and spring coiled, for 
use with thermocouples, RTDs and 
thermistors.
To achieve a superior jacket 
construction, OMEGA has employed 
the latest in jacketing material:  
TPE (thermoplastic elastomer), 
a unique family of thermoplastics 
which exhibits characteristics 
previously found only in rubber 
compounds. TPE is extremely tough 
and flexible, and has excellent 
abrasion resistance. Our special 
construction technique yields an 
expansion rate of up to 500%.
OMEGA’s retractable sensor cables 
are specifically recommended for 
use with electronic-type indicators, 
either panel, handheld or bench 
type models. The cables should 
not be used with self powered, 
unamplified analog meters, such as 
OMEGA® Series 7000 pyrometers. 
Retractable sensor cables have 
hundreds of applications: oscillating 
machinery, handheld surface 
probes, or wherever retractable 
sensor cables are required.

How To Order
1. Fill the 1st box (1) with desired ANSI Calibration. Use ANSI 
symbols “J”, “K”, “T”, “N”, “E” for thermocouple calibration; “RTD” 
for resistance temperature detector; or “TH” for thermistor.
2. Fill in 2nd box (2) with retracted coil length in feet: 1' (30 cm),  
2' (60 cm), 3' (90 cm), or 4' (120 cm).
3. Fill in 3rd box (3) with termination style number (one end).
4. Fill in 4th box (4) with termination style number (other end).
