The Fuji Electric PXF5ABR2-FBCA1 is a self-tuning 1/8 DIN (48 x 96 mm) compact temperature and process controller with a 50 ms sampling speed. That sampling rate means it reacts to process upsets within a single mains cycle — useful for fast-responding thermal processes like injection mold barrel zones or small reflow stages where a slow loop lets temperature overshoot past the setpoint.
The 1/8 DIN (48 x 96 mm) form factor fits the standard panel cutout for this class. The 50 ms sampling speed is the loop update interval; the self-tuning algorithm adjusts PID parameters on startup or after a setpoint change. No IP rating is listed, so plan for a clean, dry enclosure.
