The Fuji Electric PXF4APR2-JBKA1 is a self-tuning 1/16 DIN (48 x 48 mm) compact temperature and process controller with a 50 ms sampling speed. That 50 ms loop rate means it catches fast thermal transients in processes like injection molding or extrusion where a standard 250 ms controller would lag and overshoot. The self-tuning algorithm sets PID gains automatically on startup, which saves a commissioning pass on multi-zone lines.
Where it fits
The 1/16 DIN (48 x 48 mm) footprint slides into a standard panel cutout. Panel depth is shallow enough for most enclosures. The 50 ms sampling speed and self-tuning make it a direct swap for older Fuji PXR-series units or other 1/16 DIN controllers in the same cutout — no panel rework.
