The Fuji Electric PXF5AEP2-JVCA1 is a self-tuning 1/8 DIN (48 x 96mm) compact temperature and process controller with a 50ms sampling speed. It's meant for a panel cutout where you need tight loop control in a small footprint — think ovens, packaging heat seals, or plastic extruder zones where the process can't wait on a slow controller.
The 1/8 DIN form factor (48 x 96mm) fits the standard panel cutout that's been around for decades. If you're swapping out an older controller from another brand, the hole is the same size — just check the depth clearance behind the panel. The compact depth leaves room for wiring duct and terminal blocks in a crowded enclosure.
