Extension Wire - Multicable - Twisted Pairs and Overall Shielded -

Twisted Pairs, Individually & Overall Shielded (SD) - Stranded wire is standard.

Multicable extension wire is a cost effective and space saving method of running multiple sensor leads to the process instrumentation. Stranded wire is standard. Multicable extension wire is constructed to protect the thermocouple circuits from electrical interference. Overall shielded wire has an Aluminum Mylar Tape ( AMT ) covering the bundle of twisted wire pairs and a copper drain wire. This gives protection from external noise. Example: 20KX04-PP The individually and overall shielded wire ( SD ) has the Aluminum Mylar Tape ( AMT ) wrapped around each twisted pair and again over all of the pairs. A copper drain wire is included with each pair and a copper drain wire is included with the overall shielding. This gives excellent protec- tion against external and internal noise. Just add “ SD ” to the end of the part number . Example: 20KX04-PP-SD Numbers in the part numbers signify the number of pairs, i.e. 01 = 1 pair, 02 = 2 pairs, etc. Special limits can be specified by doubling the type letter in the part number. Example: 20KKX04-PP Stainless steel Over Braid is available for many wires. It is used to protect from abrasion and fraying of wires and is an electric shield- ing when grounded. Eight is the designation for 304 Stainless Steel - “ OB8 ”. Just added letters to the end of the part number. Example: 20JX02-PP-OB8 If a communications wire is required add “ CW ” to the end of the part number. Example: 20KX04-PP-CW
