Description
Belden 3112A 004 is a Type KX thermocouple extension cable with 1 pair 20 AWG solid Chromel & Alumel conductors for temperature signal extension in industrial environments. It features PVC insulation with yellow & red color coding, plus an overall Beldfoil® shield (100% coverage) with a 22 AWG (7x30) TC drainwire to help reduce electrical noise. A yellow PVC outer jacket with ripcord supports easier pulls and routing. It is rated 300 V (PLTC, CMG, UL AWM 2464) and supports indoor/outdoor use with sunlight resistance.
