What ships in the carton
The PXF4APE2-JV1A1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller with a 50ms sampling speed. That sampling rate means it catches fast thermal transients in processes like injection molding or small-zone reflow — the controller updates its output every 50 milliseconds, so it doesn't lag behind a rapid temperature swing.
Panel fit and integration
The 1/16 DIN (48 x 48mm) cutout is the standard panel-mount footprint for compact controllers — it drops into the same hole as any other 1/16 DIN unit, so a panel cut for an older controller accepts this one without rework. Depth behind the panel is typical for this class; allow clearance for the screw-terminal block and any option cards.
