CS325DMCBL-L Replacement Cable for the CS325DM-L

Overview

The CS325DM cable is used for differentially transmitting data and power over twisted pairs to the CS325DM-L Silicon Irradiance Reference Sensor. This premium industrial Ethernet cable has controlled characteristic impedance for each twisted pair, making it suitable for maintaining high signal fidelity on the RS-485 signals with minimal signal reflections and excellent noise rejection. Jacket material is designed for outdoor use including UV exposure resistance and temperature performance of -40 to +75°C. Agency approvals include UL AWM Style 2463 (80C, 600V) and NEC/CEC (UL) CMX OUTDOOR. The cable has a high-flex construction with a jacket that can be pulled in conduit in addition to its resistance to weld spatter and oil.

The CS325DMCBL-L includes a connector on one side of the cable for matching any user-specified length of 33117 Ethernet cable to a CS325DM Silicon Irradiance Reference Sensor. The other side of the cable is pigtailed and tinned.
