The TE Connectivity 1274531-1 is an N-type plug, male pin, part of the Blindmate series designed for RF interconnect applications where the mating face is not directly visible during engagement — typical in rack-and-panel or bulkhead installations.
RF performance and construction
The 50 Ohm impedance and 11 GHz frequency limit define the usable bandwidth — this plug handles signals from DC through the lower X-band, making it suitable for base station, antenna feed, and test equipment interconnects. The 1000 V rating supports applications where DC bias rides on the RF carrier, common in remote antenna tower amplifiers and bias tees. The threaded fastening provides vibration-resistant coupling typical of N-type interfaces. The brass body with tin finish and gold-over-brass center contact give corrosion resistance for outdoor or industrial cabinet environments. The PTFE dielectric maintains stable impedance across the full temperature range.
