Product description
Principles of operation
The M4000 multiple light beam safety device consists of a sender unit and a receiver unit.
A distinction should be made between active/active systems and active/passive systems:
On the active/active system, sender unit and receiver unit are in separate housings, the
sender and the receiver. The light beam is emitted from the sender and is incident to
the receiver.
On the active/passive system, sender unit and receiver unit are in a common housing
(M4000 Advanced A/P). The light beam is emitted from the sender unit and is deflected
by the deflector unit M4000 Passive (mirror deflection or fibre-optic deflection) by 180°
back to the receiver unit (see Fig. 2). As a passive element, the deflector unit does not
require any electrical connections.
For the exact number and distance of beams, please see chapter 13.3 “Dimensional
drawings” on page 120ff.
The dimension of the light path between sender and receiver (or between the M4000
Advanced A/P and M4000 Passive) must not exceed the maximum permissible scanning
range (see “Technical specifications” on page 113ff.).
On active/active systems, sender unit and receiver unit synchronise automatically by
optical means. An electrical connection between both components is not required.
The M4000 is modular in structure. All optical and electronic components and assemblies
are housed in a slim and torsionally rigid housing.
M4000 Advanced
The M4000 Advanced multiple light beam safety device is available with 2, 3 or 4 beams.
Other configurations with up to 12 beams are possible on request. The maximum scanning
range (dimension of the light path between sender and receiver) is 70 m.
M4000 Advanced A/P
The M4000 Advanced A/P is available with 2 or 4 beams. The maximum scanning range
(dimension of the light path between the M4000 Advanced A/P and the M4000 Passive) is
dependent of the number of beams as well as the utilized M4000 Passive and is 7.5 m
max.
M4000 Area 60/80
The M4000 Area 60/80 multiple light beam safety device is available with a monitored
area length from 300/600 mm to 1800 mm. The beam separation is 50 or 57 mm (reso-
lution of 60 or 80 mm). The maximum scanning range is 19 m (M4000 Area 60) or 70 m
(M4000 Area 80).
