Notes on handling spring-loaded terminals with push-in technology
The terminal area of the spring-loaded terminals is rectangular, and the maximum overall
dimensions of the conductor to be wired must not exceed 1.5 x 2.4 mm.
Attention must be paid to the orientation of the terminal area, which may call for vertical 󹪝tting
of rectangularly crimped cables.
To make optimum use of available terminal area, you are advised to choose a form of crimping
that creates a corresponding rectangular contour. Trapezoidal crimping is generally very highly
suitable in this case.
