Takex TXF-20TDM Instruction Manual

Thank you for purchasing this product. Before using the product, please read this instruction manual to ensure correct operation.
This unit is a battery operated photoelectric beam sensor consisting of a
transmitter and a receiver.
The direct path between the transmitter and the receiver forms the
detection line. When this detection line is interrupted (light is obstructed
for 50ms or more), the receiver outputs a signal.
The battery operated design allows this unit to operate without an external
power supply over a long period of time.
In order to ensure that the detection line has sufficient margin of sensitivity,
adjust the direction of the light beams before putting the system into
operation. Providing sufficient margin of sensitivity reduces the malfunction
caused by dense fog, heavy rain, frost, snow, and other weather conditions.
Double modulated beams are designed to
distinguish external lights.
It increases the reliability in the outdoor security
system.
By combining a wireless transmitter, external
wiring becomes unnecessary, which can
substantially reduce wiring material costs and
related work.
In addition, this unit realizes longer battery life
due to its low current consumption.
Environmentally friendly
RoHS compliant. (2011/65/EU ＋2015/863/EU)
The unit has been designed to achieve dust and water
ingress protection equivalent to IP55, as well as a
protection measure against insects.
Keeps birds and small animals away from the
sensor, to reduce false alarms.
Prevents rain and snow from streaming down the
front side of housing, to avoid false alarm.
Enables clear view for easy beam alignment.
The vivid color of the internal structure can be
recognized easily at distance during the beam
alignment procedure.
The color differs between transmitter and receiver
for easy installation and checking.
The angle can be adjusted to ±95° in the horizontal
direction, and the lock mechanism can reduce the
optical axis shift due to vibration.
By combining intermittent and continuous sounds,
it is possible to judge if the amount of light received
is good without a multimeter.
