What it is and what it does
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.
Lifecycle and sourcing posture
For BOM freeze or compliance documentation (RoHS, REACH, UL, IEC), the manufacturer provides the standard declaration pack. Nameplate markings on the unit match the order code for PO-to-part traceability.
Panel integration notes
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.
