September 14, 2011 - INTACTON introduces OPTIPACT-L series optical sensors for slip-free, non-contact length and velocity measurement of yard and piece goods. Like all OPTIPACT sensors, the OPT-L detects movements in two axes along with surface standstill and direction of movement.
Measuring merely 98 x 42 x 35 mm, the compact sensors need less installation space and can be easily integrated in virtually any application. They are equipped with a class 1 laser illumination and do not require any additional safety precautions. The sensors enable users to develop new applications: they are especially suited for smooth and glossy surfaces such as metals, plastics or foils which are problematic for other sensor systems.
Fitted with an IP65 housing, OPTIPACT-L sensors are installed at a 30 mm standoff distance from object being measured and tolerate distance deviations of up to ±6 mm. Furthermore, working distances between 15 and 60 mm are possible on request. The sensor can measure maximum speeds of 4 m/s with a 10 µm resolution. The resolution can be freely adjusted in order to meet different application requirements. The measurement uncertainty is lower than 1%.
A graphical user interface enables an easy set-up and adaptation to different measuring conditions. Additionally, programmable digital outputs allow users to precisely control the measurement of piece goods or cutting processes. The outputs can generate a signal when the speed drops below or exceeds a pre-set value, when a direction change occurs or when a selected length is reached. Minimizing installation and maintenance costs, the sensors ensure a reliable, efficient quality control which is gentle to the material for smooth and glossy surfaces. With costs per piece comparable to conventional encoder/measuring wheel solutions, the sensors are considerably more cost-efficient than all similar contact-free systems.
