Belden 8451 010, Multi Conductor Twisted Pair Cable 2C 22 AWG Shield PVC

Belden 8451 010 is a 1 pair 22 AWG twisted pair cable with a PVC - Polyvinyl Chloride jacket for low voltage signal and control wiring in Indoor - Riser applications. It uses 22 AWG stranded (7x30) TC - Tinned Copper conductors with PP - Polypropylene insulation and a paper wrap. An overall Beldfoil® shield (100% coverage) with a 22 AWG stranded TC drain wire helps reduce noise in analog signals (4-20ma, 0-10v, ...) and low voltage digital control (24v, …). It is rated 300 V and supports an operating temperature of -20°C to +75°C.
