Overview

Spintronic junctions allow the current to branch, just like an electrical junction of three wires. Each sprocket is one of the three paths for current.

If you're looking to get extra parts, this is a good kit to get, since junctions are the most commonly used part in spintronic circuits.

Detailed description

These junctions use a planetary gear arrangement, where the top sprocket is the sun, the middle sprocket is the ring, and the bottom sprocket is the carrier of the planets. The sprockets are of different diameters, but the internal gearing ratios are chosen such that it behaves according to the following equation:

vbottom = vmiddle + vtop

where:
- vtop is the velocity of a tooth on the top sprocket
- vmiddle is the velocity of a tooth on the middle sprocket
- vbottom is the velocity of a tooth on the bottom sprocket

Lucy X. ★★★★★

I needed extra branches for my circuit and this value pack delivered—the sprockets click into place securely and the current splits evenly across all three paths.

Chloe S. ★★★★★

Wasn't sure I needed spares until one junction in my build started acting flaky, and now I keep a few of these in the drawer. The branching across three paths works exactly like the wiring diagram promised, no surprises.

Andrew J. ★★★★★

Bought a handful of these to keep on the bench for when a junction shorts out mid-build, and the three-path sprocket design means I can branch current exactly like wiring three leads together. Fit was clean on the first one with no trimming needed. Nice to finally have spares that just drop in.
