Picuture[edit]

Would be great to have a picture of this. The connector descriptions are extremely useful!

The photo is of SMB connectors. SMCs are threaded. - Alan Bloom —Preceding unsigned comment added by 173.164.133.8 (talk) 20:29, 10 January 2011 (UTC)[reply]

Erreur sur la photo : c'est celle d'un SMB !!! — Preceding unsigned comment added by 193.251.35.241 (talk) 15:21, 21 July 2011 (UTC)[reply]

removed the picture of an SMB connector and added a link to Amphenol's page describing the SMC series. By the way, I *think* the main difference between SMC and 10-32 microdot is that the 10-32 male (pin) has female threads, while the SMC male (pin) has male threads. Can anyone confirm this? Should it be added to the article? ThanksSMesser (talk) 15:22, 12 August 2011 (UTC)[reply]

Merge[edit]

Consider merging all sub miniature co=nnectors on to one page called Sub miniature RF connectors

Connector impedance[edit]

Connectors aren't rated in impedance (Z). A load might be, Cable impedance is rated in ohms per foot. — Preceding unsigned comment added by 71.211.238.56 (talk) 02:03, 6 June 2013 (UTC)[reply]

Cable impedance is *not* rated in ohms per foot. Coaxial impedance is a function of the capacitance between the core and braid, and the inductance of each. Because these two values vary linearly with length and with each other, cable impedance is independent of length. --2601:644:8102:8F00:A9B1:5001:2F3E:CC0E (talk) 15:45, 23 March 2016 (UTC)[reply]

Connectors *are* in fact rated in impedance: A coaxial connector, like a coaxial cable, is a coaxial transmission line. A coaxial transmission line's impedance can be calculated using the outer diameter of the inner conductor, the inner diameter of the outer conductor, and the dielectric constant of the material in between the two conductors. The inner conductor in a connector is the pin or socket, and the outer conductor is the shell. The surface contours of these components are complex, given the mechanical requirements to mate with the other connector as well as with the cable. A poorly-designed connector will cause an impedance mismatch between cable and connector, resulting in reflections, attenuation, noise, and loss. --2601:644:8102:8F00:A9B1:5001:2F3E:CC0E (talk) 15:34, 23 March 2016 (UTC)[reply]
