HD/SD SDI Professional Digital Video BNC to Micro BNC
Micro BNC Plug to BNC Male or Female Plug 
Various Lengths (other lengths available on request)

Micro BNC are used by:
the new 2021 BlackMagic Video Assist 3G
Embrionix SFP Modules
etc.

All my cables are custom made by myself using care, experience and the right tools.

Cable: Argosy Image 360 LSOH HD digital Video Cable 
Equivalent specification: Belden 1855ENH, Bryant Precision SDI Video Cables (Small) or DRAKA HD-Pro 0.6/2.8 AF HDTV

Connectors: Coax BC 55C3G (Male Plug) / Coax BC 57C3G (Female Plug)
With the higher requirements of Serial Digital Video, HDTV, 3G etc., we now offer "true" 75 Ohm BNC connectors, 3G-SDI compatible BNC connectors. To achieve a nominal impedence of 75 Ohm, these connectors are designed with a reduced dielectric around the pin.

Connector Micro BNC plug: UBN 1855E (Coax part number: 67-005-B66-FA)

Complete with heat shrink cable strain relief.

These Micro BNC plugs make a locked connection when engaged with a bayonet twist lock movement like their full size BNC connectors. When connecting to Embrionix SFP Modules two sockets are very closely spacedthis makes the unlocking ring difficult to grip with fingers.
For ease, a pair of thin nosed pliers may be used for disconnecting (connecting is straightforward). Simply grip the knurled ring and rotate it anti-clockwise to disengage the plug, Pulling on the cable, heat-shrink strain relief or ferrule will not unlock the connection unless the knurled ring is rotated. A tool is available for very high density socket arrays where plugs can only be accessed from behind.

Description 

Micro BNC 75 ohm straight crimp plug. This true 75 ohm plug is designed for Full HD 1080p applications and general use up to 12GHz. With 15Uin gold plated centre contact and annealed crimp zones these connectors offer a long term durable solution. Suitable for all cables in group FA. When COAX Connectors developed their range of Micro BNC connectors, they were specifically designed to be interchangeable with HD BNCs from Amphenol. If equipment is built using HD BNCs, it is entirely safe to connect with Micro BNCs and vice versa.
United States Patent No. 9,071.013 applies.

Our Micro BNC 75 ohm connectors are designed for HD & UHD Broadcast, Telecom, HDcctv, Instrumentation and similar applications that require high performance in an high density package.  The unique patented coupling nut allows the use of a special tool to disconnect the connectors when they are closely mounted. Tested to beyond 12GHz and exceeding the requirements of SMPTE ST 2082-1, these connectors are used in Full HD1080p (3G), HD-SDI and are fit for Ultra HD 4K (12G) applications.  With a diameter of only 7.8 mm, mounting density is increased by 4 times when compared with a standard BNC.

If you require a custom length please buy the next length up and post a note to me with the purchase.

EG: If you require a 25cm cable please buy the 50cm cable and notify me of a custom cable length in the purchase message box where you complete your purchase, or message me in the normal way if you wish.

Note: I measure cable length from the back of the crimp ferrules at each end(please see picture). 

This cable, Argosy Image 360, has a minimum bend radius of 51mm, thus using  circa 160mm to make a 'U' bend.
That is not to say that you can not impose a tighter bend then 51mm radius but if you do the cable will not deliver the stated bandwidth.
The cable is stiff compared to lower performance / bandwidth cables.
Flexible high performance cables are available (please see my ebay shop)  but only in thicker, heavier and more expensive forms.
