Technical Description
The mini optical series of
sensors are among smallest
sensors in the world. Mini
optical sensors require
almost no space and with
their low mass (from a mere
1.2 grams) they are absolute
lightweights. They can be
easily installed inside moving
machine parts like robot
arms. Our smallest sensors
measure 2 mm in diameter.
The mini optical sensors are
the preferred solution for all
applications where the
highest mobility, smallest
sizes, and optimal part
resolution is essential.
The mini optical sensors
represent unique alternative
to traditional fiber optics. Its
foremost advantage lies in
highly flexible electrical
conductors made from
copper cord encased within a
corrosion-resistant polyure-
thane sheath. Unlike fiber

– Robotic end-effectors
– High-performance altern-
atives to fiber-optics
Features
– Smallest sensing head in the
industry
– Detects objects as small as
0.05mm with high resolution
amp
– 10 kHz with high speed
amp
– Detect ambient light
sources with high speed
amp
– 50 ms off delay available in
universal amp
– Amp can be panel mounted
or DIN rail mounted
– Sealed to IP67 standards
– Protected against short
circuit and polarity reversal
optic cables, these conduc-
tors can withstand very high
stresses from flexing and
twisting without placing any
limitations on the bending
radius.
In addition to their small size,
the mini optical sensors offer
exceptional capabilities for
detecting small objects.
When used with standard
resolution amplifiers, objects
as small as 0.2mm can be
detected. With the high
resolution amplifiers, objects
as small as 0.05mm can be
sensed. This incredible
sensitivity makes it possible
to sense the thin wires of
components used in small
electronic assemblies.
Potential applications for laser
sensors can be reliably and
less expensively handled by
mini optical sensors.

The Kodak card is moved at 90º angle step by step in fr ont of the dif fuse sensor. Several levels
of sensitivity are shown below, using an amplifier with standard resolution.
While the standard 50 x 50mm Kodak test card is used for determining sensing range, very few
applications use this target. The following chart shows approximate performance of these
sensors using several different wire sizes as a target and an amplifier with standard resolution.

Successful detection with the Balluff miniature optical thru-beam system is based on three
factors: target size, beam intensity, and beam range. The following chart illustrates the
approximate performance of different wire diameters breaking the beam at certain beam ranges.
If a sizeable target does not break the beam, lowering the intensity of the beam via the control
amplifier will usually remedy the problem.

Technical Description
The miniature series of
compact diffuse sensors are
among the smallest self-
contained optical sensors in
the world. The emitter and
receiver, as well as all
electronics are contained in
these small packages.
The smooth tubular housings
are easy to mount with
clamping brackets. Threaded
barrels are furnished with nuts
for easy mounting.
The rectangular housing
makes for easy positioning in
tight spaces. In fact, two

models come standard with
quick disconnect and

background suppression
model is ideal highly for
reflective surfaces, dark
objects and location with
extremely close and highly
reflective backgrounds.
All versions come standard as
PNP, normally open output.
Cable out models come
standard with 2 meters of
PUR cable. Contact the
factory for availability of other
logic or cable styles.
