The light barriers FT201 are safety devices for the access automation. Every pair consists of a modulated infrared transmitter and a receiver with a double relay output contact. Transmitters and receivers have an optical system (lens) to concentrate the ray, an electronic circuit for immunity against sun rays and a synchronous system for installations of two pairs of photoelectric cells. Maximum range: 60 m.
The ILB device consists of a transmitter and a receiver with double relay safety outputs. Its operation sequence is based on the technology of the infrared light via a gallium arsenide diode. Maximum range: 50 m.
The light barrier is achieved by emitting an infrared light beam with frequencies of more than 1000 hertz. The receipt of the light beam happens by a corresponding infrared-sensitive photocell. Maximum range: 25 m.
VEDO180 is a relatively small light barrier device, which can be installed simply and fast. Its infrared beam can be adjusted from the inside for more than 180 ° horizontally, so that its installation is also possible at places where normal light barriers cannot be applied. Furthermore the self-centered lens also corrects possible faults in vertical direction for several degrees. The power supply can be in DC voltage as well as in AC voltage with 12 or 24 V. VEDO180 is also equipped with the synchronous function for the installation of two light barrier pairs. Maximum range: 25 m.
