The PXF4APR2-JV1A1 is a compact 1/16 DIN (48 x 48 mm) temperature and process controller from Fuji Electric's PXF4 series, with a 50 ms sampling speed and self-tuning capability.
The 1/16 DIN (48 x 48 mm) panel cutout is the standard small-footprint size for temperature controllers. It fits the same 45 x 45 mm panel hole as every other 1/16 DIN controller on the market, so a swap-in replacement for an existing unit is straightforward — no panel rework needed.
Where it's deployed
This class of controller is used in industrial thermal control: plastic injection molding machines, packaging seal bars, drying ovens, and extrusion lines. The 1/16 DIN size suits multi-zone machines where panel space is tight — you can pack several units side by side on a standard DIN-rail adapter or panel-mount bracket.
For BOM-line commitment, the key fit check is the 50 ms sampling speed and self-tuning algorithm — if your process requires faster than 50 ms loop updates (e.g., thin-film coating or high-speed packaging), you would need a controller with a sub-10 ms sampling rate. Otherwise, this unit covers the standard thermal PID application space.
