These analog (RH) 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 BTA uses a side-mounted lock. These BTA connectors are perfect for educators or other users who need to set up a Custom Vernier analog sensor which produces a voltage that changes from high to low or vice versa.
