The 12mm CT Clamps that come with the Senseable Transmitter as standard have the following dimensions:
62mm x 42mm x 22mm.
They can fit around a cable 12mm in diameter.
Larger CT Clamps - We can supply larger CT Clamps (25mm maximum cable diameter) if required. Please contact us. We don't make these freely available on the webshop in order to keep things simple.
Please note if talking to electricians - electricians talk about cables in mm2 cross-sectional area, not diameter. A 12mm2 cable is very small, and this can cause confusion if the electrician thinks that is the maximum size the CT Clamp can fit around. A 12mm diameter cable has a cross-sectional area of 113mm2.
