Number one when it comes to the detection of transparent objects.

These retro-reflective photoelectric sensors in metal housing with glass optics were designed specially for detecting PET- and glass bottles, plastic foils as well as flat glass. Intelligent configuration options in combination with precise temperature compensation facilitate stable, long-term operation. The patented tracking process extends the cleaning interval many times over; short response times and minimal jitter ensure reliable control of fast processes.

• Degrees of protection IP 67 and IP 69K
• Corrosion-resistant metal housing with thread and glass optics
• Especially designed for the detection of PET, film, and glass
• Calibrated aBEAM optics for use without alignment
• Sensitivity adjustment via teach button or potentiometer
• Autocollimation principle
• Automatic dirt/cleaning compensation (tracking) increases the interval between cleaning sessions
• High extraneous light protection through A²LS

Special light-spot profile for single-lane bottle transport

In this series with metal housing, everything has been optimized for the detection of PET and glass bottles that are transported in a single lane. The turnable device plug simplifies integration in constrained spaces.

• Indicator LEDs with all-round visibility
• Degrees of protection IP 67 and IP 69K
• M12 turning connector
• Metal housing with glass optics
• Especially designed for the detection of PET and glass
• Teach-in via step switch or control line
• Autocollimation principle
• Automatic dirt/cleaning compensation (step/peak tracking) increases the interval between cleaning sessions
• Increased availability through warning output
