Description

212 spring clamp PCB terminals

The 212 family provides spring connections for 0.2–1.5mm² conductors in 3.5mm and 5mm pitches. V and R configurations have different pin arrangements and PCB footprints. Select the exact pitch and orientation before laying out the board.

PCB layout and dimensions

Dimensions are in millimetres. N is the number of poles. Two pin rows belong to the single row of terminal positions; they do not indicate two independently rated terminal levels. All four models use 1.20mm PCB holes, nominal 0.80mm-wide and 0.40mm-thick pins, and nominal 3.50mm solder tails.

For TB21-212V/5.0, the specified pin-width tolerance is 0.80mm +0/−0.05mm and solder-tail length is 3.50±0.30mm. Use the separate V and R pin layouts rather than rotating a shared footprint.
