Key Specifications
Description
2.92mm Jack (Female) Straight Bulkhead Cable Connector for .141", such as Rosnol RSF 141, DC - 26.5 GHz, VSWR ≤ 1.20, 50 Ω, with Soldered Cable Entry.
The ROSNOL K2EA50-0141A/9X is a 2.92mm bulkhead jack connector designed for .141 cable, optimized for RF applications up to 26.5 GHz. With a 50 Ω impedance, VSWR ≤ 1.20 (≥ 20.83 dB), and insertion loss ≤ 0.05 × √F (GHz), it ensures reliable signal transmission and low reflection. The connector features a screw-lock coupling mechanism, soldered center contact, and soldered cable entry. It supports mating cycles ≥ 500 and maintains RF leakage ≥ 100 dB up to 1 GHz. Operating temperature range is −40°C to +85°C.
The center contact is made of beryllium copper with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. The body is stainless steel with passivation, the insulator is PTFE, and the gasket is silicone rubber. The connector meets MIL-STD standards for thermal shock, corrosion, vibration, and moisture resistance, and is mechanically compatible with 3.5mm and SMA interfaces.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
