Torch holder (x3) - (Black) LJ12A3-2-Z/AX

 

- V1 Full Set - 7 sensors ferruled

- V2 Full Set - 6 sensors JST + 1 ferruled

Best for

  • Replacing a single limit or homing sensor on a BlueCarve Spark plasma table
  • Rewiring a whole machine with a V1 full set (7 sensors, ferruled) or a V2 full set (6 JST plus 1 ferruled)
  • Matching the colour-coded YL, YR, X, Z and torch holder positions

Not for

  • Mixing V1 and V2 parts: V1 machines use green terminals, V2 machines use JST SM plugs

Adam's Tip

Check whether your machine is V1 or V2 first, then pick the position (YL, YR, X, Z or torch holder). The colour and termination in each option name match the harness, so the new sensor plugs straight in.
