Installation
Assembly instructions
–
Install the devices solidly on a stable, vibration-free
holder.
–
Orient the devices so that the control elements are
always easily accessible.
–
Be sure that the orientation of the devices cannot
change during startup or in normal operation.
Especially the emitter and receiver must not be
permitted to move relative to each other, since
otherwise incorrect measurements and failed object
detection can result.
–
Locate the devices where they are protected against
the accumulation of dust, dirt or liquids.
–
Do not install the devices in a location where they are
exposed to direct sunlight or strong ambient light,
since excessive ambient light can result in faulty
measurements.
The device can be installed horizontally or vertically.
Fastening options:
OWIS system rails (www.owis.eu)
The mounting holes are compatible with the system rails
and slides made by OWIS, sizes SYS 65 and SYS 90.
Custom fastening system
M4 screws are used for fastening. Use either the two
through-holes on the top side (50 mm spacing) or the two
threaded holes (depth 6 mm; spacing 34 mm).
Mounting brackets from Balluff
The mounting brackets BAM02HE (large) or BAM02HF
(small) are available as accessories. This stainless steel
mounting system allows flexible positioning and easy
alignment of the transmitter and receiver by slotted holes.
3.2
Electrical connections
Connect the emitter and receiver using a 4-conductor
cable (all conductors through-connected 1:1). The emitter
has an M12 male plug and the receiver an M12 female.
An 8-pin M12 male plug is used for power supply and data
output.

Use the control menu to configure the analog outputs as
voltage output (0 to 10 V) or as current output (4 to 20 mA)
(see
4.3 Configuring the analog
direction (0 ⇒ 10 V or 10 ⇒ 0 V, and 4 ⇒ 20 mA or
20 ⇒ 4 mA) is also configurable. The default setting for
both analog outputs is voltage output with rising signal
direction (0 ⇒ 10 V).

Mounting tolerances
To achieve the best possible results, do not exceed the
following positioning tolerances:
Maximum permissible parallel offset ±1.0 mm in both
directions.
