Measuring 38.5mm in length, these insert-type adapters provide reliable signal termination, protecting sensitive test equipment like oscilloscopes from damage. Trusted by professionals, they offer an affordable, high-quality solution to maintain signal integrity and safeguard your valuable devices. ## Description Package Included: 2 x Adapter Review: Good quality - These are an inexpensive and high quality way to terminate your connections into your oscilloscope or other test equipment at 50 ohms. I prefer these to using my internal 50 ohm resistors in my oscilloscope just in case I go over voltage. I'd rather burn one of these than the front end of my very expensive scope! These actually have a decent low power rating. I view it has cheap insurance! Review: Great Value! - It works as specified. ## Features - 1. Please allow 1-3mm error due to manual measurement.Pls make sure you do not mind before you bid. - 2. The color may have different as the difference display,pls understand. - Electroplating bright all copper BNC male and femalehead. Internal 50Ω matched impedance. - Link Mode: Insert Type; Material: Copper - Impedance:50 ohm; Length: 38.5mm; Width: 15mm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07G566JC7 | | Best Sellers Rank | #2,333 in Audio & Video Connectors & Adapters | | Brand | MOTOKU | | Connector Type | bnc | | Current Rating | 50 Amps | | Customer Reviews | 4.5 out of 5 stars 129 Reviews | | Finish | Copper | | Finish Type | Copper | | Item Package Quantity | 1 | | Manufacturer | MOTOKU | | Mfr Part Number | 8541770572 | | Model Number | 8541770572 | | Number of Ports | 2 | | Package Quantity | 1 | | Power Plug Type | No Plug | | UPC | 675663428135 | | Unit Count | 2.0 Count | ## Product Details - **Connector Type:** bnc - **Brand:** MOTOKU - **Finish Type:** Copper - **Number of Ports:** 2 - **Item Package Quantity:** 1 ## Images ![2X Copper Adapter 50Ohm 38.5mm Insert Type BNC Feed Through Terminator - Image 1](https://m.media-amazon.com/images/I/61yk+-d63yL.jpg) ## Questions & Answers **Q: What is the wattage rating for these terminators?** A: Although the termination can only handle 1/4 watt, one can put a 6dB attenuator in front of it to essentially increase the overall power rating to 1 watt. One could even place a 20dB attenuator in front of the 1/4 watt termination to increase the overall power rating to 25 watts; of course the attenuator would need to be rated for at least 25 watts. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by O***Y on May 3, 2026* These are an inexpensive and high quality way to terminate your connections into your oscilloscope or other test equipment at 50 ohms.

I view it has cheap insurance! ### ⭐⭐⭐⭐⭐ Great Value! *by A***M on September 4, 2025* It works as specified. ### ⭐⭐⭐⭐ Good cheap 50 ohm terminators *by P***E on April 15, 2024* They work as desired for on cheap oscilloscope which lacks built-in 50-ohm termination mode. A DMM confirms they're 50 ohm. I got these on a recommendation from another reviewer, as one of the better options for having appropriate impedance at a wide range of frequencies, but really I don't have the equipment or expertise to evaluate that myself. The packaging was not good: a little cardboard box, roughly 5cm x 7cm x 11cm, the two little metal adapters inside, and no bubble wrap or wadded-up paper or anything else, so they had plenty of space to knock around against each other in shipping. They came through fine, maybe I was a bit lucky. ## Frequently Bought Together - MOTOKU 2X Copper Adapter 50Ohm 38.5mm Insert Type BNC Feed Through Terminator - BNC 50 Ohm Terminator, 5-Pack BNC Male Plug Coaxial Cable Adapter Connector - MOOKEERF BNC Male to BNC Male Coax Cable, 50 Ohm RG58 Coaxial Cable with BNC Connectors, 3ft (2Pcs) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/103975620-2x-copper-adapter-50ohm-38-5mm-insert-type-bnc-feed](https://www.desertcart.com.au/products/103975620-2x-copper-adapter-50ohm-38-5mm-insert-type-bnc-feed) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-07-25*
