CAB-HD44 - Low Noise 44-way D-Sub Cables for Precise Ion Chamber Readout

The CAB-HD44F-XXLN-HD44M is a 44-way screened cable specifically designed to work with Pyramid ionization chambers and multi-channel electrometers. This cable features an anti-triboelectric coating (N.E.Wire “Newtral”), offering an efficient solution to particle therapy beam position measurement, dosimetry, and multistrip ionization chamber readout. Every unit is individually tested for offset current to ensure optimal performance, while color-coded identification bands provide a convenient visual guide for users. The cable configuration comprises 44 individual cores of 26 AWG 66/44 tinned copper, insulated with polyethylene and coated with the same anti-triboelectric material.

Connectivity is assured through high-density 44-pin DSub female-to-male connectors, connected pin to pin. The connectors' screens are linked at both ends and to the connector shells to provide a consistent data transmission environment. The cable's offset leakage current is less than 2pA on each channel wire on a terminated cable. This low-noise, multiway cable has a rated maximum voltage of 65V, a durable PVC outer jacket in orange, and an overall outer diameter of 10.7mm. It can be flexibly bent with a minimum radius of 70mm, enabling it to fit in a variety of installation setups.

Pyramid Technical Consultants offers the CAB-HD44F-xxLN-HD44M in custom lengths to suit your specific requirements. In addition to customer cable labeling, color code options such as red, green, blue, and white bands at each end are available. It's important to note that while a maximum length of 100 feet (30.5m) is available, a recommended maximum length for particle therapy ionization chamber readout is 33 feet (10m) to minimize potential electrical interference and ground loop effects and to control capacitive load on the electrometer.
