That is similar but a press-fit type and is for a 2mm plug. Here https://www.mklab.rhul.ac.uk/~tom/1mm_test_sockets/ are some photos. The first two are of some sockets and plugs I found in one of my spares draws, purchased by one of my now-retired predecessors, probably years ago. I checked the plugs' pins which are definitely 1mm dia. Curiously the sockets would not accept them -- the 1mm pins are just too fat. So it appears there must have been sockets made for less than 1mm dia. pin plugs in the past. The other 2 photos are of a NIM crate's FP showing the sockets, some of which are broken. These sockets definitely take the 1mm plugs. Other than in the pin receptacle size they appear identical to my spares draws sockets. Yesterday I spoke to a colleague who thought he might have some similar sockets in a box amongst his old spares. He did. His sockets did take the 1mm plugs w/o problem which will now enable me to do the repair jobs. Interestingly his box still had the suppliers labels present. They were from RS Components with stock nos. 444-062 and 444-056 (for red & black types). RS's website lists them as 'discontinued'. RS confirmed this and told me the manufacturer was Deltron. I could not find them listed so presume Deltron no longer makes them. The photo of a current Ortec crate I linked to in the OP has quite similar looking sockets, although obviously the pin-size can't be deduced from it. Unless Ortec now use some other pin size sockets, it must be that similar sockets are still available from other suppliers... I contacted Ortec (now Ametek)'s tech support but have not heard back from them yet. Regards Tom Crane. Ps. The email address in the header is just a spam-trap. -- Tom Crane, Dept.

Hopefully the Ortec/ Ametek will be able to help you. Here in the States we have ~2mm tip jacks which fit the probes on your typical DMM. As a silly idea maybe replace all the connectors with 2 mm tip jacks? George H. |

At least in the UK I have found that Kodak's cheapest nastiest batteries survive in high current drain applications where Duracells have leaked on me. EveryReady & Panasonic also seem to be OK at least in the UK. > Talking about 9V batteries is not helping ! I won't use Duracell any more. I can't tell if it is a problem with high quality counterfeit or their actual genuine manufacture batteries. There was a time in the past when they were the copper topped gold standard! -- Regards, Martin Brown |
