50ms sampling in a 1/4 DIN package
The PXF9APA2-MBMA1: That sampling rate matters for processes where the thermal time constant is short — injection mold cavity temperature or thin-film extrusion — because the controller sees the error sooner and the PID loop can correct before the overshoot exceeds the process window.
Panel fit and deployment context
The 1/4 DIN (96 x 96mm) cutout is the standard panel-mount footprint for this controller class — it fits the same panel punch as other 1/4 DIN instruments, so a retrofit or replacement drops into the existing cutout without panel rework. The compact depth behind the panel suits control cabinets where DIN-rail space is already committed to I/O and power supplies.
