Distance sensor uses transit time measurement

The Wenglor X1TA101MHV80 distance measurement sensor from Treotham Automation uses the transit-time measurement principle to measure the distance between the sensor and the object.

The sensors have scratch-resistant optics and the emitted light can be switched off. Using a suitable reflector at the object, a highly accurate position measurement at large distances is also possible. Configurations are selected using an on-board menu and can be protected by a password.

The transmitter and the receiver are integrated into a single housing. As the sensors measure the distance between the sensor and the object and utilise the principle of transit-time measurement, the object’s colour, shape and surface characteristics have practically no influence on measurement results. Even dark objects can be reliably recognised against bright backgrounds.

The sensors’ measuring range is determined by object remission and the size of the reflector (if used). Maximum range of the X1TA101 series is up to 100m on 4×RQ100BA reflectors, or up to 30m on a plain 200×200 mm reflector sheet.

The sensors work on a supply power of 18 to 30 Vdc and the configuration can be easily set using the three on-board buttons and screen, including a password (PIN). The sensor offers analogue output (0-10 Vdc, 4-20 mA).

All settings can also be configured using a PC and uploaded to the device. RS-232 interface connections RxD (5) and TxD (4) are linked to minus (pin 3, green), and can be connected to the corresponding terminals at the communication partner. The interface makes use of the software handshake procedure. The modular safety system can be used for zone control in the robotics, manufacturing, packaging, mining, materials handling and component assembly industries.
