Panel fit and deployment
The PXF4AEY2-JVVA1: The 1/16 DIN (48 x 48mm) cutout is the standard panel-mount size for this class of controller — it drops into the same hole as any other 1/16 DIN instrument, so a panel already punched for a Fuji PXR or a competing brand's 1/16 DIN unit will take this controller without rework. The 50ms sampling speed is the key selection parameter here: if your process has a time constant under a few seconds (small heaters, thin-film processes, gas-fired burners), the faster loop update keeps the output from lagging behind the actual temperature swing.
