Product Overview
Amphenol RF 132170 is a straight, in-series SMA female-to-female bulkhead adapter rated from DC to 18 GHz at 50 Ohms. It mounts through a panel or enclosure wall, securing with the included hex nut and internal tooth lock washer to create a stable, low-loss coaxial feed-through. Gold-plated brass body, beryllium copper contacts, and PTFE insulation. Both jacks accept standard SMA male plugs.

- Operating temperature: -65°C to +165°C
- Included hardware: 1x hex nut, 1x internal tooth lock washer
Applications
- RF lab engineer drilling a D-flat hole into a shielded test chassis, mounting this adapter through the panel, torquing the hex nut to spec, and connecting SMA patch cables on both sides to route a signal to a spectrum analyzer without breaking enclosure shielding
- Field technician mounting this adapter through the pre-drilled panel of a NEMA-rated wireless gateway enclosure, securing it so it cannot spin when external antennas are tightened, and connecting an internal SMA pigtail to a U.FL-to-SMA cable
- SDR hobbyist building a custom enclosure for an RTL-SDR, HackRF, or LimeSDR, feeding the RF signal cleanly through the chassis wall without introducing impedance mismatch or mechanical strain on the internal board connector
- Ham radio operator mounting this in a homebrew amplifier or antenna tuner enclosure to bring a clean 50-Ohm feed-through to the front or rear panel
- FPV builder installing a panel-mount SMA jack on a carbon fiber quad frame or video receiver enclosure, then threading an external antenna onto it without the connector spinning or stressing the internal coax
Frequently Asked Questions
Will this work with RP-SMA connectors used on consumer Wi-Fi routers and most FPV gear?
No. The 132170 uses standard SMA jacks - the center receptacle is a female socket. RP-SMA connectors have a male pin in a female-threaded body. The threads will engage but the center contacts will not mate correctly. If your cables or antennas are RP-SMA, you need the 132170-10RP-RP variant instead.
Is this rated for outdoor or weatherproof enclosures?
No. The standard 132170 does not include an O-ring gasket and carries no IP rating. For outdoor or sealed enclosures requiring IP68 weatherproofing, look for the 132170-12 variant, which adds an integrated O-ring seal.
What panel thickness is compatible with this adapter?
Panel thickness compatibility depends on the length of the external threads. Verify the maximum panel thickness against the mechanical drawing for this part before installation - the hex nut and lock washer must be able to thread on fully and clamp the panel to hold the adapter securely.
Is this compatible with 75-Ohm coaxial systems - cable TV, video distribution, or BNC-terminated coax?
No. This adapter is a 50-Ohm component. Connecting it into a 75-Ohm system will cause impedance mismatch, signal reflections, and potential degradation of sensitive equipment. It is also not a physical fit for F-type, BNC, or other 75-Ohm connector families.
What is included with this adapter?
One SMA female-to-female bulkhead adapter, one hex nut, and one internal tooth lock washer.
Forty years of RF connector manufacturing behind a part that still comes out of the bag looking like it left the factory yesterday - pick it up, mount it clean, and get your signal through the wall.
