## Features

- All-in-one design – integrated sensor and controller eliminates external hardware, cables, and complexity
- Zero recalibration – sensor adapts automatically to any material (clear, opaque, metallic, nonwoven, mesh)
- High resolution – 0.0635 mm (0.0025 in) hardware resolution across the entire sensing width
- Material-agnostic detection – patented fiber-optic technology based on light scattering and spatial filtering
- IP67 protection – sealed aluminum housing withstands harsh industrial environments (IP68 available on request)
- Native industrial Ethernet – EtherNet/IP, PROFINET, EtherCAT, Modbus/TCP, CC-Link IE Field Basic
- Vacuum compatible – operates reliably in vacuum chamber applications

## Benefits

- Stop paying for separate controllers – all-in-one design eliminates external hardware and reduces total system cost
- Eliminate integration complexity – just power and one Ethernet cable replaces multi-component wiring
- End unplanned downtime from cable failures and connector issues between sensors and controllers
- Stop losing hours to sensor recalibration when switching between materials
- Prevent hidden scrap from temperature-related inaccuracies that plague ultrasonic sensors
