The 284093-7: It uses a rising cage clamp termination — the M3 screw tightens a clamp that pulls the wire against a current bar, giving a gas-tight connection across 16-30 AWG. The green polyamide (PA66) housing carries a 13.5 A per-position rating at 300 V, suited for moderate-power PCB terminations in industrial controls, power supplies, and panel wiring where a screw-terminated, field-serviceable connection is preferred over a crimp or IDC.
Sizing the Connection: Wire Range and Torque
The 16-30 AWG range covers most control wiring — solid or stranded — and the 0.68 Nm (6 Lb-In) torque spec is firm enough to prevent loosening under thermal cycling without stripping the M3 brass screw. The rising cage clamp pushes the wire against a flat current bar rather than wrapping a screw head around it, so fine-stranded 30 AWG won't get mangled. Brass contacts and clamp with nickel plating resist corrosion in cabinet environments.
Interlocking Sides for Multi-Position Builds
The side interlocking feature lets you snap multiple 284093-7 blocks together side-by-side to create a wider terminal strip without extra hardware or bus bars. Each block stays individually replaceable — if one position fails, you pull that block out and slide a new one in without re-terminating the whole row. The pitch stays consistent across the joined blocks, so the PCB footprint aligns across the assembly.
