The PXR3-TEC2-4V0A1: The 1/32 DIN form factor (48 x 24 mm panel cutout) is the smallest standard controller size — it fits where panel space is tight, like a multi-zone injection molder or a lab oven with several zones stacked. The self-tuning algorithm means it auto-calculates PID parameters during startup, so you don't need a thermocouple simulator and a laptop to commission it. The 16 ramp/soak segments let you program a multi-step thermal profile (e.g., ramp to 200°C, soak 10 min, ramp to 150°C, soak 5 min) without an external programmer.
Lifecycle stage is current — Fuji Electric is still manufacturing this model. No PCN or EOL notice is available. For a BOM freeze, this part is a safe line item; no need to qualify a replacement yet.
