3. The ACOTOM process
3.1. The birth of a revolutionary technology
We put the rst contactless encoded security sensor with a revolutionary process on the market in 1993.
It uses a double-coded magnetic eld and a diagnostic output, independent of the safety contacts, which
traces the product's position. Today, this device is still leading thanks to many benets that remain
unmatched to date; it is called the "ACOTOM process3".
3.2. Principle of the ACOTOM process3
The system consists of:
- Two inviolable and independently coded ma-
gnetic eld detectors (redundancy)
- A hysteresis control circuit at 2 mm
- A circuit that guarantees a distance of less
than 14 mm, for the prevention of the passage
of the ngers
- An automatic periodic safety check
- Protection of the safety contacts at 1/4 of their
breaking capacity to avoid any sticking
- A LED which indicates that the decoding is
done, without any anomaly
- A diagnostic output that indicates an error or
that the door is not in the closed position
- Serialization up to 65 sensors without loss of
performance level
- Direct control of dangerous movement without
using an intermediate safety box, with PL d and
SIL 2.
