These digital (LH) British Telecom connectors are primarily used by our English friends across the pond but here at SparkFun we like to use them for Vernier sensors. These 6-pin connectors are very similar to the RJ11s we use here in North America except instead of a bottom-mounted hook lock, the BTD uses a side-mounted lock. These BTD connectors are perfect for educators or other users who need to set up a Custom Vernier digital sensor which produces a voltage that needs to be measured like temperature, force, light, or sound.
