Overview

The SDMX50SP is one of three 50 ohm, coaxial, 8:1 multiplexers that can be used in a TDR100-based system. It consists of a surge-protected multiplexer circuit board enclosed in a metal housing and a separate strain-relief bracket. Both the multiplexer housing and strain relief bracket have holes drilled at a 1” spacing. This allows the SDMX50SP to be mounted onto a wall or attached to the backplate of a user-supplied enclosure or Campbell Scientific enclosure (e.g., ENCTDR100, ENC12/14, ENC16/18).
