Photoelectric Sensors with Simple Setup Apply “Time-of-Flight” Measurement via PMD Technology – The O5D Series from ifm
New sensor series offers the advantages of PMD technology: long ranges and reliable background suppression
ifm’s O5D Series photoelectric sensors integrate the “time-of-flight” sensing principle with PMD (photonic mixer device) technology to provide reliable sensing in industrial automation applications. The advantages of PMD technology include extremely long sensing ranges, reliable background suppression, visible red light spot for set up and high excess gain. Application markets include conveying, material handling, steel, paper, automotive and wood.
Time of Flight principle
The Time of Flight principle measures a distance based on the time it takes to travel to an object and back to the receiver. The time period is directly proportional to the distance traveled.
Long sensing range with reliable detection
PMD “time-of-flight” technology enables long sensing ranges up to 2 meters (6.5 ft.) and eliminates the need for sensors with reflectors. The sensor offers reliable background suppression with no false triggers from highly reflective objects such as stainless steel.
The O5D Series sensors offer reliable optical performance independent of target color. Whether shiny, matte, dark or light objects, the O5D provides superior background suppression.
Simple setup via pushbuttons
The switch point can be set easily by using the sensor’s plus/minus (+/-) pushbuttons. A visible red light spot helps to align the sensor, and a numeric display shows the distance set. The O5D100 model will display range in centimeters and the O5D101 model will display in inches.
The Class 2 laser with a visible red light of 650 nm has a spot diameter of less than 5 mm. The M12 connection can be easily mounted with a variety of mounting brackets from ifm.
