The rising cage clamp termination (screw-driven clamp that pulls a cage up against the wire) gives a gas-tight connection that holds up under thermal cycling better than a simple screw-and-plate design. Wire acceptance spans 12 AWG down to 30 AWG, so a single block handles both the main feed and the smaller control wires in the same assembly. ## Wire Entry at 35° — a Space-Saving Detail The wire termination orientation is 35° (145°) relative to the board plane, meaning wires approach the block at a shallow angle rather than standing straight up. That matters when the enclosure lid clearance is tight — you gain about 10-15 mm of headroom compared to a vertical-entry block. The interlocking side feature lets multiple blocks snap together side-by-side into a continuous strip, so a 16- or 24-position assembly is just two or three of these 8-position units ganged together, no DIN rail or separate jumper bar required. ## Installation Specs That Matter on the Bench The clamp and screw are both brass with nickel plating, which resists corrosion in humid cabinet environments. The housing is polyamide (PA66) nylon 6/6 — a standard UL94 V-2 rated material for this class of terminal block, though the specific flame rating isn't listed in this entry. The published torque spec is 0.79 Nm (7.0 Lb-In) — that's the value to set your screwdriver clutch to; overtightening strips the M3 screw thread in the nylon housing. Contact plating is brass with tin, adequate for the rated current but not intended for frequent re-termination cycles — tin-on-tin connections cold-weld slightly on first mate, so a wire inserted and torqued should stay put.","metaTitle":"TE Connectivity 1546074-8 Buchanan Terminal Block, 8 Pos","metaDescription":"TE Connectivity Buchanan 1546074-8 8-position PCB terminal block, 5.08mm pitch, 17.5 A, 300 V, rising cage clamp, 35° wire entry.
