Fuji Electric PXF5APE2-FVCA1 Temperature Controller, 1/8 DIN

The PXF5APE2-FVCA1: The 1/8 DIN (48 x 96mm) panel cutout is a standard size — fits the same hole as every other 1/8 DIN controller, so swapping an older unit into an existing panel is a direct mechanical fit. The 50ms sampling speed means it reads the sensor input and updates the output every 50 milliseconds; for a plastic injection mold or a furnace zone that's responsive enough to catch thermal transients without needing a faster (and pricier) 25ms controller.
