SMT Terminal Block for Board-Level Power Distribution
The TE Connectivity 1-2383942-1 is an 11-position, single-level Termi-Blok terminal block from the Buchanan series, designed for surface-mount termination on a PCB. The 3.50 mm pitch provides enough spacing to handle the 12 A per-circuit rating without forcing an unusually wide board footprint — a practical balance for distributing power or control signals inside an industrial enclosure. The black polyamide housing carries a rising cage clamp termination for each position, secured by an M2 screw torqued to 0.5-0.6 Nm (4.4-5.3 Lb-In).
The 12 A current rating at 300 V is typical for a 3.50 mm pitch terminal block — it handles moderate power loads like a 24 VDC sensor bus or a 120 VAC control transformer secondary. The 18-28 AWG wire range covers most solid and stranded field wiring used in panel cabinets; no ferrule is required for the screw clamp, but stranded wire benefits from a ferrule to prevent strand fan-out under the cage. The nickel-plated copper alloy contact and clamp resist corrosion in the mildly humid environment of a NEMA-rated enclosure.
SMT Assembly and Line Feed
No secondary wave-solder or hand-solder operation is needed after reflow.
