I am looking for small quantities of British Telecom Analog (BTA) left and right hand sockets (receptacle) to connect to some sensors with the corresponding plugs:http://www.vernier.com/support/sensor-pinouts/
The first two pin-out diagrams depict how the two plugs of opposite handedness are used. I looked in a lot of places including ebay and ebay.uk and farnell. I am just not finding them. I figured I must have used the wrong name when searching. If I try to search American phone jacks in digikey I probably won't go very far compared with keyword RJ11.
A cable looks like this:http://www.vernier.com/products/accessories/cb-bta/
So for someone in UK, what do you call these plugs and connectors?
Where do you buy these connectors?
Where to buy them in US?
