The Fuji Electric PXF4AEP2-0B1A1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. That 50ms sampling means it reads the input and updates the output every 50 milliseconds — fast enough to catch thermal transients in a small oven, a reflow zone, or a packaging heat-seal bar before the process drifts outside tolerance.
Nameplate markings on the unit match the order code for PO-to-part traceability.
The 1/16 DIN (48 x 48mm) cutout is the standard panel-mount footprint for this class. Panel thickness between 1.0 and 3.5 mm accepts the included mounting bracket. The self-tuning algorithm eliminates manual PID gain scheduling on most thermal loads — set the setpoint and let the controller characterize the loop during the first heat-up cycle.
