The PXF5APA2-JBVA1 is a Fuji Electric PXF-series 1/8 DIN (48 x 96 mm) compact temperature and process controller.
The 1/8 DIN form factor (48 x 96 mm panel cutout) is a standard panel-mount size for temperature controllers, fitting the same cutout as legacy Fuji PXG or PXR series units. The 50 ms sampling speed is fast enough for thermal loops in extrusion, packaging, and heat-treat applications where overshoot must be minimized — it updates the PID output every 50 ms, which is roughly 3× faster than a typical 150 ms general-purpose controller.
