The Fuji Electric PXF4APS2-0V1A1 is a self-tuning 1/16 DIN (48 x 48mm) compact temperature and process controller that samples at 50ms — fast enough for tight thermal loops on plastic injection barrels, hot-runner manifolds, or small furnace zones where overshoot costs scrap.
The 1/16 DIN (48 x 48mm) panel cutout matches the standard DIN 43700 footprint — drop it into the same hole as any legacy Fuji PXF or competing 1/16 DIN controller. The 50ms sampling speed means it updates the PID loop every cycle, so it pairs naturally with fast-acting SSR outputs for electric heaters or with pulsed DC valves for gas-fired burners.
