The task
In the production process for transparent films, the films are transported from one station to the next using roller conveyor belts. Optical sensors are used to verify the presence of the films in order to initiate the next production step.
The challenge
The films are not only transparent and reflective but also round. Additionally, the mounting of the sensors between the rollers of the conveyor belt requires them to be as compact as possible.
Our solution
The FT 25-BH reflex light sensor with BlueLight technology is the ideal solution for these specific requirements. Using a blue LED, the sensors excel at detecting transparent, reflective, and round objects. Limited installation space poses no challenge for the sensor, which is both compact and robust—making it perfect for mounting between the rollers of a conveyor belt.
Your advantages
- Compact sensor with BlueLight technology and finely adjustable background suppression
- Accurate detection of both highly light-absorbing and glossy objects
- Superior operation even with highly reflective backgrounds thanks to SensoPart ASIC technology
- Easy alignment through a clearly visible light spot
- Sensor setting via teach-in, control input and IO-Link
- Robust, fiberglass-reinforced plastic housing
