Twin Beam
PHOTOELECTRIC BEAM SENSOR PB-20TE(K)
Outdoor 66ft.(20m)/Indoor 135ft.(40m)
The TAKEX intelligent“TWIN”photoelectric beam is designed to meet the highest standards of quality and reliability for photoelectric beam intrusion detection. Unique twin beams are synchronized to work together to reinforce the range and stability in severe weather conditions. The "intelligence" comes from having 4 different selectable frequencies which allow the stacking of beam sets to create a "Wall of Light". The system has a rotary optical system for easy installation and the special lens design aids in proper alignment.

Feature
SELECTABLE FREQUENCY
Includes 4 separate selectable frequencies which can stack up without crosstalk for high security applications.
HIGH RELIABILITY
Synchronized twin beams reduce false alarms caused by flying birds and falling leaves.
The outdoor maximum arrival distance is 10 times longer than the operating distance, which allows for reliable operation in poor weather conditions.
EXTERNAL LIGHT PROTECTION
Trouble-free condition in 50,000 lux illumination fluctuation is assured by external light compensation circuit a filter, specially designed, that cuts visible rays effectively. Excellent tolerance against sun light, automobile head light, fluorescent light or mercury light.
EASY BEAM ALIGNMENT
The special view finder allows for fast aiming and assures good alignment. Equipped with monitor jack to check sensitivity.
ROTARY OPTICAL SYSTEM
The optical system of both the transmitter and receiver can be rotated a full 180degrees which allows for side aiming.
Therefore the units do not have to be mounted face to face and the beam direction can not be discerned by simple observation.
INSECT PROTECTION
A sealed optical system prevents intrusion and interference by insects.
OTHER FEATURES
* Automatic Gain Control circuit loaded
* Wide adjustment (horizontally +/-90degrees, vertically +/-10degrees)
* Pole mounting kit included
PROTECTION AGAINST FROST/DEW
As a special hood is attached on sensor cover, beam protection continues without interruption even when the cover is screened by frost or dew.
