Where can I find BTA and BTD connectors and sockets?

If you want to build your own sensors, connect Vernier sensors to your own interface, or build your own cables, extensions, interfaces, or adapters, here is how to get all the connectors and sockets we use.

We chose these connectors because they click into place and students know when the sensors are connected. The BT (British Telecom) connectors are quite common in the UK, but they can be hard to find in other countries, especially in small quantities.

Cables:

1. For analog input on LabPro, LabQuest, Go!Link, or CBL 2 or analog output on LabPro, the LabPro/CBL2 Analog Cable, order code CB-BTA, $5 will work. This cable has a white, right-hand release BTA connector on one end and bare wire on the other. You could also use Breadboard Cable (Analog), order code BB-BTA, $10 if you're building a sensor on a breadboard.

2. For digital input or output on LabPro, LabQuest, or CBL 2, use LabPro/CBL2 Digital Cable, order code CB-BTD, $5. This cable has a left-handed release BTD connectors on one end and bare wire on the other.

3. For digital connectors, there is another option: The Digital Sensor Cable, order code MDC-BTD, $5 has a white, left-handed release BTD connector on each end. Cut the cable in half to expose the wires and you will have two cables.

The following cables will work for the original CBL:
1. For analog input on the original CBL the LabPro/CBL2 Analog Cable, order code CB-BTA, $5 will work. This cable has a white, right-hand release BTA connector on one end and bare wire on the other.

2. For sonic input, the Digital Sensor Cable, order code MDC-BTD, $5 will work. This cable has two white, left-handed release BT connectors on each end. Cut the cable in half to expose the wires, and you will have two cables.

3. For digital input or output, the CBL Digital Cable Kit, order code CBL-DGK, \Contact Us will work. This has a black Digital connector on one end and bare wires on the other. Note that the digital input and digital output connectors on the original CBL are the same, but they are not the same as the sonic connector.

Sockets:

Prototyping board adapters:
Analog Proto Board Connector, order code BTA-ELV, $10 and Digital Proto Board Connector, order code BTD-ELV, $10: These are just sockets for the analog and digital sensors with pins on the bottom design for plugging into a breadboard or prototyping board with the standard pin spacing.

BTA to DIN Adapter, order code BTA-DIN, $5 cut in half:
This will give you a analog (BTA) socket with bare wire on the other end.

BTA to DIN Adapter, order code BTA-DIN, $5, as is
You can also use the BTA-DIN adapter to get to a connector style that is easier to obtain, a DIN plug. (Note: AutoID lines are not supported on this adapter).

Digital Extension Cable, order code EXT-BTD, $12 cut in half:
This will give you a digital (BTD) socket with bare wire on the other end. This cable is slightly more expensive because it is 2 meters long.
