The PXF4APC2-MV1A1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. It's a current-production part, so you can spec it into a new panel or replace a failed unit without worrying about last-time-buy windows.
The 1/16 DIN (48 x 48mm) form factor is the standard panel cutout for compact controllers — fits the same 45 x 45mm panel hole as every other 1/16 DIN unit, so swapping in a failed controller from another brand is straightforward. The 50ms sampling speed means it updates the control output every 50 milliseconds, fast enough for most thermal processes (ovens, furnaces, packaging seal bars) but not for sub-second injection-mold temperature spikes. Self-tuning means the controller automatically calculates PID parameters during startup — no manual tuning required for typical loads. That saves commissioning time on a line changeover.
Lifecycle stage is current — Fuji Electric is still manufacturing this order code. That makes it a safe pick for both new designs and as a critical spare for existing panels.
