CDM Electronics: Cable assemblies for PTC

CDM Electronics has announced the availability of a comprehensive array of semi-custom and custom cable assemblies optimized to meet the latest requirements of positive train control (PTC) systems. CDM's PTC Coaxial/RF and Ethernet (RJ45) assemblies and interconnect systems are engineered to ensure the functionally and reliability of PTC wireless networks. They're also offered in a variety of configurations, including those featuring low-smoke zero-halogen.

CDM's semi-custom and custom cable assemblies are ideal for employment in the full spectrum of PTC systems, regardless of their complexity, sophistication or level of automation, company officials said in a press release. They are most commonly used to support onboard systems; communication/antenna towers; wayside interface units; base stations; signal, switch and operations control; and SCADA systems. Additionally, the assemblies can be used in signal crossing gates and surface transit station systems.

Assemblies are manufactured using Times Microwave's LMR® Series low loss cables, which are self-healing and feature an operating temperature range of -40° F to 185° F. Low-smoke zero-halogen assemblies meet all applicable CMR, UL/NEC, CSA and NFPA safety requirements.

Lightning and surge protection products operate in the frequency range from DC up to and including 6 GHZ. To provide design flexibility, coaxial/RF connector options include BNC, N-Type, SMA and TNC interfaces in both cable- and surface-mount formats.

Ethernet cables are offered with straight-, right- and left-facing RJ45 interconnects. Coaxial/RF custom and semi-custom cable assemblies are made in CDM's facility in Turnersville, New Jersey. Most assemblies are RoHS-Compliant.
