Description

A BNC Female Bulkhead LMR-200 Clamp Connector (BNC F BH LMR 200 CLAMP) is a 50-ohm RF panel feed-through connector designed to attach LMR-200 coaxial cable through a single-hole chassis or bulkhead cutout.Instead of needing a crimping tool, it uses a threaded clamp nut to mechanically lock the cable braid and jacket in place, making it ideal for field installations and re-usable terminations.Part Designation BreakdownBNC: Quick twist-and-lock bayonet coupling style.F: Female connector interface (Jack).BH: Bulkhead mount (threaded front barrel, lock washer, hex nut, and optional O-ring gasket for mounting through a round or D-flat panel hole).LMR 200: Precision-sized for flexible, low-loss LMR-200 coaxial cable (~4.95 mm / 0.195 in outer diameter).CLAMP: Screw-tightened collet/nut assembly for toolless outer braid termination and field repairability.Technical SpecificationsParameterSpecificationGenderFemale (Jack)Mounting StyleBulkhead Mount (Single-hole circular or D-flat cutout)Cable CompatibilityLMR-200, RG-58, RG-142, RG-400 (~4.95 mm OD)Termination TypeClamp (Threaded nut compresses internal metal sleeve/gasket)Impedance50 $Omega$Frequency RangeDC to 3 GHz / 4 GHzVSWR$le 1.20$ (DC to 3 GHz)Working Voltage500V RMS peakInsulation Resistance$ge 5000text{ M}Omega$Body MaterialNickel-plated brassCenter Pin ContactGold-plated phosphor bronze or brassInsulatorPTFE (Teflon)Key Benefits & FeaturesField Repairable: Can be attached or reassembled using standard wrenches, making it easy to replace or modify on-site without carrying dedicated hex crimpers.Single-Hole Bulkhead Seal: Requires only one drilled panel hole rather than 4 screw holes. Most models include an O-ring under the panel nut to prevent dust and water penetration into the chassis.Anti-Rotation “D-Flat” (Optional): Many bulkhead bodies feature a flat side on the threaded barrel to prevent the connector from spinning in the panel during cable attachment.Common ApplicationsOutdoor Wireless Enclosures: Passing low-loss LMR-200 antenna feeder lines into weather-sealed radio enclosures (Wi-Fi, LoRa, LTE, GPS).Test Bench & Laboratory Gear: Panel feed-through connections on signal generators, analyzers, and custom RF prototype boxes.Marine & Vehicular Installations: Weatherproof bulkhead penetration points for radio communication antennas.
