Photoelectric switch

Main features
The Z3N series logo detection photoelectric switch scans the surface of the inspected paper through its own emitted light source. The amount of reflected light varies due to different surface colors, thus achieving recognition of color markings.
Coaxial optical path design has stronger adaptability to high reflectivity paper surfaces such as aluminum foil.
It has multiple light sources to choose from, such as white, blue, green, red, etc., which brings convenience to distinguish various colors.
The light spot is small and the resolution is extremely high.
High response speed of 0.1-1ms, able to adapt to the control needs of various packaging machines, bag making machines, and printing machinery.
Excellent internal circuit design, excellent resistance to various electromagnetic and stray light interference, stable operation, and error free operation.
Equipped with sensitivity adjustment knob, it can be adjusted without the use of tools.


Main technical parameters
Detection method: coaxial reflection type
Detection distance 10mm ± 2mm
Supply voltage Vs DC10V-30V ± 10% ripple<>
Consumption current below 45mA
Light source chromatography available in red, green, blue, and white colors
Light spot Φ 0.5 ～ Φ 1.5
The allowable deviation for detecting the angle of light perpendicular to the surface of the object being tested is ± 15%
Response time 0.1-1ms
Output mode can be selected as bright or dark
Output indicator red LED
Output voltage high level Vs - (≤ 1.5V) low level (≤ 1.2V)
Carrying current 200mA (max)
The circuit protection device Vs has reverse polarity protection for voltage and short circuit protection for output. When the load current I.>200mA, the switch automatically trips, and when I. ≤ 200mA, the signal automatically returns. At the same time, it has protection against any misconnected wires.
Sensitivity adjustable in a single loop
