SMD Screw-Clamp Terminal Block for Automated Assembly
The screw rising cage clamp termination (M2 screw, torqued to 0.5-0.6 Nm) secures the stripped conductor against a nickel-plated copper alloy clamp — no ferrule required for stranded wire, though a ferrule improves pull-out consistency in high-vibration environments. The black polyamide housing includes a board guide feature that aligns the part during pick-and-place, reducing tombstoning risk through reflow. The SMD format suits automated assembly lines where a through-hole terminal block would require an extra wave-solder step.
Pitch and Position Count — Board Footprint Match
At 12 positions on a 0.150" (3.81mm) pitch, the 1-2383941-2 occupies a board edge length of roughly 1.65" (42 mm) from the centre of the first to the centre of the last position. This is the standard footprint for a 12-way 3.81mm-pitch terminal block — any replacement must match both the pitch and the number of positions to align with the PCB layout. A 5.08mm-pitch block (like a 12-position 5.08mm variant) would not fit the same board footprint without a layout change.
