The Fuji Electric PXF4ACR2-0VMA1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed.
The 1/16 DIN form factor (48 x 48mm panel cutout) is the standard footprint for panel-mount temperature controllers — it fits the same cutout as legacy Fuji PXF and most competitive 1/16 DIN units, so a swap doesn't require re-punching the panel. The self-tuning algorithm automatically calculates PID parameters during startup, which saves commissioning time on ovens, furnaces, and packaging lines where the thermal load changes with product mix.
