Wiring a 2-Position Power Block Without Over-Torquing the Screw
The 1546073-2: The rising cage clamp accepts 12-30 AWG wire and the M3 screw has a specified torque of 0.79 Nm (7.0 Lb-In); exceeding that strips the brass threads, while under-torquing leaves the conductor loose under vibration. The black housing and vertical wire entry (top entry, perpendicular to the PCB) suit it for control cabinets, power supplies, and industrial I/O boards where a serviceable screw termination is preferred over a crimped connector.
Ganging Blocks for Multi-Circuit Runs
The 1546073-2 carries an interlocking side feature that lets multiple 2-position blocks snap together into a longer strip — useful when a 4-, 6-, or 8-position assembly is needed without ordering a different base part number. The 5.08 mm pitch stays consistent across the gang, so the PCB footprint can be laid out as a repeating pattern. For a fixed multi-position requirement, the 1546073-2 at 2 positions per level is the building block; there is no single 4-position variant in this exact form factor, so ganging is the intended approach.
