PRODUCT DESCRIPTION

The sensor contains a transmitter and receiver.
As illustrated, an infrared beam, projected by the
transmitter, is reected back to the receiver.
The protection loop is formed along the path from the
transmitter to the reector and back to the receiver.
When this protection loop is interrupted, the receiver will
initiate an alam.

＊As this sensor needs only one-side wiring, you can use it

in places where it's difcult to wire on two sides.

＊Beam alignment can be adjusted at the sensor side only.
＊Pole attachment (option parts : BP-60A) is available for

both sensor and reector.

＊L ttings (option parts : BL-11) is available for reector

mounting.

ACCESSORY

OPTION PARTS

Thank you for purchasing our photoelectric beam sensor.
This sensor will provide long and dependable service when properly installed.
Please read this Instruction Manual carefully for correct and effective use.
Please note : This sensor is designed to detect intrusion and to initiate an alarm ; it is not a burglary-preventing device.
TAKEX is not responsible for damage, injury or losses caused by accident, theft, Acts of God ( including inductive
surge by lightning ), abuse, misuse, abnormal usage, faulty installation or improper maintenance.

・Hazardous weather such

as heavy rain or frost may
cause false alarms.

 Sensitivity allowance of

reective type beam
sensors is comparatively
lower than that of
standard type beams.

・Remove all

obstructions (trees,
clothes lines, etc.)
between sensor and
reector.

・Avoid strong light from the

sun, antomobile headlights etc.
directly shining on sensor.

 When strong light stays in the

optical axis for a long time, it
dose not cause malfunction but
will affect the product life.

・Do not install the unit

on places w here it
may be splashed by
dirty water or direct
sea spray.

・Do not install the

unit on unsteady
surfaces.

・Do not place highly

reective objects
between the sensor and
the reector as they are
likely to create a
protection loop and
prevent the sensor from
making a detection.

PROTECTION DISTANCE

Sensitivity

allowance

Sensitivity allowance-protection
distance curve for PB-11BE

＊Protection distance (between sensor/reector)
 should be placed in the rated range.
＊Sensitivity allowance will be greatly decreased when the protection distancedeviates from the rated range.

(See the sensitivity allowance-protection distance curve for PB-11BE)

BEAM ALIGNMENT

・Fine tuning using a volt meter is required. (See section 5)

HEIGHT OF INSTALLATION

Install the sensor at a height of 31" to 39" (80 to
100cm) to catch a human target.
(Install vertically so that the center of the sensor
lens and middle part of the reector assembly are
placed at the same height.)

Using the adjustments, the lens can move
horizontally (±90 degrees) and vertically (±10
degrees) allowing the unit to work in all
directions.
(example 1 to 3)

・Avoid over head wiring.
・When installing indoors, wiring procedures

similar to those for telephone or intercoms
are acceptable. Outdoor wires should be
placed inside conouit, or underground
cable/metal shielded cable should be used.

Example 1

Example 3
(When BL-11 optional is used)

Example 2

＊The sensor and reector units should be installed uprightly and vertically.
Make sure that the reector's front side faces the sensor as illustrated.

Expansion of beam can be calculated as follows.
