The JINPAT LPHF-01L is a single-channel high-frequency RF slip ring (coaxial rotary joint) rated from DC to 67 GHz. Built around a precision 1.85 mm coaxial interface, compact nested construction, stainless steel outer conductor, and beryllium copper inner conductor, it enables continuous millimeter-wave signal transmission across a rotating mechanical interface — without signal interruption, cable wrap-up, or latency.
It is the component of choice for OEMs and system integrators who need reliable rotating RF connectivity in millimeter-wave radar, 5G antenna platforms, medical CT gantries, industrial LiDAR robots, and UAV sensor payloads.

The 1.85 mm coaxial interface delivers a working frequency ceiling of 67 GHz, covering the complete millimeter-wave spectrum demanded by 5G FR2 band (24–71 GHz), Ka/V-band satellite links, wideband radar waveforms, and high-resolution SAR imaging. Competing rotary joints capped at 40 GHz leave a gap that forces costly system-level workarounds. The LPHF-01L closes that gap in a single compact component.
The 1.85 mm connector is mechanically interchangeable with standard 2.4 mm RF connectors. Buyers upgrading existing 2.4 mm-based platforms to higher frequencies can integrate the LPHF-01L without purchasing new adapter hardware — protecting prior hardware investment and accelerating system integration timelines.
The coaxially nested design keeps the physical profile minimal. This matters directly to procurement engineers specifying components for UAV payloads, robotic joints, portable NDT probes, and high-density circuit board assemblies where size and weight are hard constraints, not preferences.
Passivated stainless steel outer conductor and beryllium copper inner conductor deliver a combination of high tensile strength, excellent wear resistance, and long-term contact stability. The result: consistent signal performance across thousands of rotational cycles, under vibration, humidity, and thermal variation — reducing maintenance intervals and unplanned downtime.
3D LiDAR robots and high-definition machine vision systems rely on real-time transmission of point cloud and image data regardless of arm rotation angle. The LPHF-01L provides the rotating RF link that keeps data flowing continuously, preserving the timing precision required for precision picking, welding, and assembly. Also suited for industrial 3D imaging systems and ultrasonic phased-array NDT scanners operating under high-speed rotation.
CT scanner gantries rotate the X-ray source and detector array around the patient at high speed while the table remains stationary. RF energy and high-resolution image data must cross this rotating boundary without interruption. The LPHF-01L's low-loss coaxial structure and 67 GHz capability make it a dependable rotary coupling between gantry and fixed frame — directly contributing to image resolution and diagnostic accuracy.
Tight mass and volume budgets in UAV sensor payloads, gimbal systems, and small robotic joints make the LPHF-01L's lightweight nested construction a direct procurement advantage. During rapid attitude changes and continuous rotational scanning, it maintains stable millimeter-wave connectivity with no dropout or latency.
Phased-array radar antennas and satellite terminal platforms require continuous azimuth rotation or beam steering. The LPHF-01L supports wideband radar waveforms and high-throughput satellite uplink/downlink channels up to 67 GHz across the rotating interface.
Yes. The 1.85 mm connector mates directly with 2.4 mm test ports and adapters with no additional hardware.
Yes. As a rotary joint (slip ring), continuous unlimited rotation is its core design function — no cable wrap-up, no rotation angle limit.
