What this controller is and where it fits
The Fuji Electric PXF4APR2-MVMA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. That 50ms sampling rate means it catches fast thermal transients — think injection mold nozzle temperature or a small reflow zone — where a slower 100ms or 250ms controller would let the process overshoot before the PID loop corrects.
Panel integration and wiring notes
The 1/16 DIN (48 x 48mm) cutout is the standard panel-mount footprint — same as every other 1/16 DIN controller on the market. The depth behind the panel is typically around 90-100mm; make sure your enclosure has that clearance before you cut the hole. Spring-cage or screw terminals depend on the specific output/input option card fitted to this order code variant.
