Product Description
The PA18C.T... is part of a
family of inexpensive general
purpose through-beam sen-
sors in industrial standard 18
mm cylindrical ABS housing.
The sensors are useful in
applications where high-
accuracy detection as well as
small size is required.
Compact housing and high
power LED for excellent
performance-size ratio.
The potentiometer used for
adjustment of the sensitivity
makes the sensors highly flex-
ible. The output type is NPN
or PNP and the output switch-
ing function is NO and NC.
• Miniature sensor range
• Range: 20 m (Axial), 16 m (Radial)
• Sensitivity adjustment by potentiometer
•
Modulated, infrared light 850 nm
• Supply voltage: 10 to 30 VDC
• Output: 100 mA, NPN or PNP, N.O + N.C.
• Degree of protection IP67, IP69K
• LED indication for output, stability and power ON
• Protection: reverse polarity, short circuit and transients
• Cable and plug versions
• Excellent EMC performance
