What This 2-Position Terminal Block Does Differently
The TE Connectivity Buchanan 1776260-2 is a 2-position, single-level PCB terminal block with a 0.200" (5.08mm) pitch — the gap that decides whether it drops into your existing board layout or forces a respin. It terminates 14-22 AWG wire via a screwless leg-spring, push-in mechanism, so no torque driver is needed on site: strip the wire to the correct length, push it into the clamp, and the stainless steel spring holds the full conductor cross-section. This is the member of the Buchanan series that solves the problem of a 2-circuit termination point on a PCB — common for sensor power feeds, control signal breakouts, or low-current distribution where a multi-position block would waste board space.
What the 10 A and 300 V Ratings Actually Mean for Your Fit
The 300 V voltage rating gives enough headroom for standard 24 VDC control loops and 120/240 VAC line-level signals; the 5.08mm pitch provides the creepage distance to support that voltage without tracking across the surface. The 14-22 AWG wire range means you can land a 14 AWG motor lead or a 22 AWG thermocouple wire in the same block — the spring clamp adapts to the strand count without needing a ferrule, though ferruled stranded wire pushes in more cleanly. The through-hole mounting with vertical wire entry keeps the block perpendicular to the board, so the wire exits straight up — useful when the enclosure lid clearance is tight above the PCB.
