1 Page 1 of 5 trans-o-prox allows you to arrange safe but inexpensive obstac interval control for automated and railborne vehicl monorail conveyors. Obstacle detection employs echo mode to prevent vehicles from collid objects. An AGV system can thus be stopped in g the impact bumpers come into play. This represen saving on maintenance costs in daily operations. Ultrasonic obstacle detection and active interval control for automated vehicles. Transponder mode renders possible active interval control of up to 10 of vehicles. It even functions perfectly around ben Dividing the route into sections is then no longer necessary. Echo and transponder modes can be set separately to two independent detect d settings are carried out via three buttons on the fro Alternatively, all settings can be carried out via the with the help of a PC or notebook. Operators can choose from two ultrasonic sensors with differ geometries and detection ranges: the wms-251/rt 501/RT. Further potential applications Interval control for railborne vehicles Obstacle detection for transfer wagons Travelling workbenches Collision protection for gantry cranes Output of interval data via the serial interface navigation purposes. The echo mode enables non-contact detection of obstacles for aut

The sensors are front of the vehicle. The sensor housings are designed so that they ca with the vehicle body. This method provides optim against mechanical damage and the vehicle is not unnecessarily.

A maste to the front of each vehicle and a slave sensor to t slave acts as an active reflector which responds to of the following vehicle and transmits an answer. T of the signal is used by the trans-o-prox on the fol compute the distance to the preceding vehicle.

Output 2 can be used a range, output 1 as a stopping range. Setting the switching thresholds for the outputs is the three buttons on the front of the unit. Alternativ parameters can be entered via the serial interface software is required for this; many terminal progra available are suitable, like the one supplied as sta Windows. trans-o-prox provides online help for e The wms-251/rt sensor has a detection range of 2,500 mm in echo mode. evaluated blind zone lies between 0 and 100 mm. is asymmetric and is clearly wider horizontally tha The red areas represent the detection zone for a s (metal tube, 27 mm dia.); the blue areas indicate t very large reflector (provided the target angle is a sensor).
