Material Recognition Sensors
Reflection-based transducers that tell one material or one sheet count from another, without touching the target.
3 sensors in this family
Sorting lines and consumer robots have to know what they are about to touch before they touch it. Optical sensors are defeated by dark surfaces, dust and gloss; contact probes wear out and mark the part.
Ultrasonic Material Recognition Sensor 1
A reflection-type ultrasonic transducer that reads back the change in frequency and amplitude of the returned wave, so metal, plastic and wood separate cleanly without any contact with the target.

Ultrasonic Material Recognition Sensor 2
The same reflection-type sensing element supplied on a twisted, colour-coded harness with a pitch connector already fitted, so it drops straight onto a board-level mating header.

Ultrasonic Material Recognition Sensor 3
A short-body reflection transducer with a fine centre-exit lead and micro connector, so it seats in a shallow boss and routes straight back to the board.

- Robotics & Home Appliance — A floor-cleaning robot has to tell carpet from tile before it drives onto it, in a housing with no room to spare.
- Industrial Sorting & Inspection — Sorting and quality inspection lines need a verdict per part, at line rate, without marking the part.
- Single and Double Sheet Detection — Telling one sheet of paper from two, with sound instead of a mechanical gate.
- Floor Material Recognition in Cleaning Robots — Knowing whether the next metre is carpet or tile, before the wet roller reaches it.
