10-position, 5.00 mm pitch terminal block for PCB mounting
The 1-1776244-0 is a 10-position, single-level terminal block from TE's Buchanan series, on a 0.197" (5.00 mm) pitch. It terminates wires via a screw with leaf spring and wire guard, and mounts through-hole to the PCB. The blue PA66 housing and tin-plated brass contacts suit general-purpose power distribution and signal wiring on a board.
Wire termination and torque specification
Wire termination uses a screw with leaf spring and wire guard, accepting 14-22 AWG conductors. The screw thread is M2.6, and the recommended tightening torque is 0.51 Nm (4.5 Lb-In). The clamp material is steel, stainless; the screw is steel, galvanized-chromate plated.
Mating orientation and board layout
Wire entry is horizontal with the board, meaning the wires run parallel to the PCB surface. The interlocking side feature allows multiple blocks to be ganged side-by-side without a separate rail.
