Würth Elektronik WR-NTYPE coaxial cables and connectors

Würth Elektronik has expanded its range of coaxial cables and connectors to include a comprehensive portfolio of N-type cable connectors to satisfy MIL-STD-348 requirements with 50Ω impedance. Jacks for connecting to the application PCB are available in straight and angled THT versions, or as 4-hole flanged panel connectors with round post or solder cup. Besides pre-assembled cables, individual cable connections are also available for field assembly.

The coax connectors are suitable for use outdoors or in harsh environments like those in radio base stations, signal distributors, GPS systems or ship antennas — just the application for which the N-type was developed. The screw connections of the THT jacks and those for mounting packages are available in protection class IP67. The gold-plated THT contacts have enhanced corrosion resistance compared to the standard tin-plated connectors, and the gold-plated phosphor-bronze centre contact material is designed to reduce component costs compared to the beryllium-copper otherwise used.

Würth Elektronik offers various assembled cables including double-shielded Low Loss 195 and Low Loss 200, which are compatible with LMR195/200 or CFD195/200. The RG316 cable with FEP sheathing, for instance, is resistant to oil, chemicals and weathering and can be used at operating temperatures from -55 to +165°C. The various N-type cable connectors are designed for quick installation of cable assemblies in small quantities and for assembly in the field. The secure screw connection is achieved without tools using a knurled union nut. Both the IP67 and RG178 bulkhead jack are also suitable for microcoaxial cables (1.3, 1.32 and 1.37).
