OMEGA™ Retractable Sensor Cable is color coded and spring coiled, for use with thermocouples, RTD’s 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.

Do these come with a certification of calibration?

Asked by: Tristan
Hi Tristan, The order would ship with Cal-1 certification. This covers all items on the order. Cal-1 is emailed with the order confirmation. Cal-1 is a statement that all items on an order will meet or exceed the advertised specifications. Best regards OMEGA
