Photoelectrics Laser, Diffuse-reflective (Colour Mark Sensor) Type LD32CND150 pages

Specifications are subject to change without notice (10.02.06) 1
Product Description
The LD32CND15 sensor family
comes in a compact 12 x
32 x 20 mm reinforced
PMMA/ABS-housing.
The sensors are useful in
applications where highaccuracy
detection as well as
small size is required.
The Teach-In function for
adjustment of the sensitivity
makes the sensors highly
flexible. The output type is
preset (NPN or PNP), and the
output switching function is
programmable (NO or NC).
The small laser spot makes
the diffuse-reflective sensor
useful as colour mark sensor.
• Miniature sensor range
• Range: 150 mm
• Sensitivity adjustment by Teach-In programming
• Modulated, red laser light 650 nm (class 2)
• Supply voltage: 10 to 30 VDC
• Output: 100 mA, NPN or PNP preset
• Make and break switching function programmable
• LED for output indication, signal stability and power ON
• Protection: reverse polarity, short circuit and transients
• Excellent EMC performance
• Accurate detection of small printing marks
