The 1546215-7: Rated 10 A per position at 150 V, it handles board-level power distribution for control signals, sensor loops, or low-current DC rails inside an industrial cabinet. The wire entry is horizontal with the board (side-entry), which keeps the screw terminals accessible from the board edge when the assembly is panel-mounted or stacked. The screw cage clamp accepts 16 to 30 AWG wire, so you can land a 16 AWG power feed or a 30 AWG thermocouple lead in the same block without changing hardware.
Wiring and termination — screw cage clamp, side entry
Wire termination is a rising cage clamp: turning the M1.6 screw (torque to 0.2 Nm / 1.7 Lb-In) lifts a nickel-plated brass clamp plate that traps the stripped conductor against the tin-plated brass contact pad. The rising cage pulls the wire into the clamp pocket rather than pushing it sideways, which keeps the conductor centred and reduces the chance of strand fan-out. The clamp and screw materials — brass with nickel plating for the clamp, steel/stainless for the screw — resist corrosion in a humid cabinet environment. Because the wire enters parallel to the PCB (horizontal orientation), the block is best suited for board-edge termination where the harness runs along the board plane. For a perpendicular wire exit, you would need a vertical-entry variant in the same series.
