It belongs to Hirose's UM series of ultra-miniature coaxial connectors, designed for internal antenna feeds, GPS modules, Bluetooth/Wi-Fi radio pigtails, and other short-reach RF interconnects where board space is tight and a snap-on mating cycle is preferred over a threaded coupling. This order code ships as a complete kit: one connector body, one heat shrink tube, one lockwasher, and one mounting nut. The heat shrink covers the crimped shield termination, the lockwasher prevents the nut from backing off under vibration, and the nut secures the jack to the panel face. ## 50 Ohm Signal Path at 2 GHz Ceiling The jack is factory-configured for 1.5D-2V, 1.5D-HQEV, and 1.5D-QEV coaxial cables — these are 1.5 mm-diameter class micro-coax cables common in handheld and portable device harnesses. The centre contact is solder-terminated; the shield is crimp-terminated. The included heat shrink tube insulates the crimp joint and provides strain relief at the cable exit. Mating is snap-on, not threaded — the jack accepts the corresponding U.FL (UMCC) plug with a positive click. The 500-cycle rating means this interconnect can be disconnected and reconnected through the life of the product without degrading the contact interface, which is typical for field-serviceable antenna ports or test-point access. ## Panel Mounting and Envelope Mounts through a panel cutout with the front-side nut — the jack body goes in from the outside, the nut tightens from behind. The lockwasher between the nut and the panel face keeps the assembly tight under vibration. This mounting style means the jack can be installed after the PCB is populated, which simplifies the assembly sequence for enclosure builds.","metaTitle":"Hirose UM-QPJ-1.5VCR3B(40) U.FL Jack, 50 Ohm, 2 GHz","metaDescription":"Hirose UM-QPJ-1.5VCR3B(40) U.FL (UMCC) jack, male pin, 50 Ohm impedance, 2 GHz max, panel mount with bulkhead nut.
