Description
TNC Reverse Polarity Plug (Male) Straight Cable Connector for RG 55, DC- 3 GHz, VSWR ≤ 1.20, 50 Ω, with Crimped Cable Entry
The ROSNOL TNC5C50-G142A/H44 is a reverse TNC plug designed for crimp or solder attachment of the center pin, and crimped cable entry. Supporting 50 Ω impedance and operating up to 3 GHz, it delivers VSWR ≤ 1.20 (≥ 20.83 dB) and insertion loss ≤ 0.05 dB. The connector features a screw-lock coupling mechanism, with axial centre contact captivation ≥ 15 N. Structurally, it has a reference body length of 29.8 mm [1.173"], with barrel diameter Ø6.35 mm [0.250"], and mating hex size SW14 [0.551"]. The rear barrel diameter is Ø3.1 mm [0.122"], ensuring compatibility with multiple cable types.
The body, coupling nut, and ferrule are made of brass with copper-tin-zinc alloy plating. The centre contact is phosphor bronze with gold plating over non-magnetic nickel-phosphorus underplating. The insulator is PTFE, and the gasket is silicone rubber. Compatible with RG55, RG141, RG142, RG223, and RG400 cables. Crimp dimensions: ferrule 5.41 mm [0.213"], centre contact 1.73 mm [0.068"].
