Laser Triangulation Sensors. RF605 Series Safety precautions · · · · Use supply voltage and interfaces indicated in the sensor specifications. In connection/disconnection of cables, the sensor power must be switched off. Do not use sensors in locations close to powerful light sources. To obtain stable results, wait about 20 minutes after sensor activation to achieve uniform sensor warm-up. The sensors have been developed for use in industry and meet the requirements of the following Directives: · EU directive 2014/30/EU. Electromagnetic compatibility (EMC). · EU directive 2011/65/EU, “RoHS“...

Laser Triangulation Sensors. RF605 Series Structure and operating principle The operation of the sensors is based on the principle of optical triangulation (Figure 1). Radiation of a semiconductor laser (1) is focused by a lens (2) onto an object (6). Radiation reflected by the object is collected by a lens (3) onto a linear CMOS array (4). Moving the object (6 – 6') causes the corresponding shift of the image. A signal processor (5) calculates the distance to the object from the position of the light spot on the array (4). Overall and mounting dimensions Overall and mounting dimensions of...

Laser Triangulation Sensors. RF605 Series Figure 3. Sensor with cable gland Overall demands for mounting The sensor is positioned so that the object under control has to be placed within the working range of the sensor. In addition, no foreign objects should be allowed to stay on the path of the incident and reflected laser radiation. Where objects to be controlled have intricate shapes and textures, the incidence of mirror component of the reflected radiation to the receiving window should be minimized. valid for sensors with serial numbers 11000 and higher

Laser Triangulation Sensors. RF605 Series Configuration parameters The nature of the sensor operation depends on its configuration parameters (operation modes), which can be changed by sending commands via the serial port (RS232 or RS485). The basic parameters are given below. Time limit for integration The intensity of the reflected radiation depends on the characteristics of the surface of the controlled objects. Therefore, the laser output power and the time of integration of radiation incident onto the CMOS array are automatically adjusted to achieve maximum measurement accuracy. The...

Laser Triangulation Sensors. RF605 Series Note 1. It should be noted that the ‘sampling mode’ and ‘sampling period’ parameters control only the transmission of data. The sensor operation algorithm is built in such a way that measurements are taken at the maximum possible rate determined by the integration time period, the measurement result is sent to the buffer and stored therein until a new result arrives. The above parameters determine how the result is read from the buffer. Note 2. If the bit-serial interface is used to receive the result, the time required to transfer data at the...

Laser Triangulation Sensors. RF605 Series Mutual synchronization Hardware zero-set/ Hardware laser ON/OFF Time lock of the result If the sensor does not detect an object, or if the authentic result cannot be obtained, a zero value is transferred. This parameter sets the time during which the last authentic result is transferred instead of a zero value. Discreteness of the time setting is 5 ms. Method of results averaging This parameter defines one of two methods of averaging the measurement results implemented directly in the sensor: · Averaging over a number of results · Time averaging...

Laser Triangulation Sensors. RF605 Series Time lock of the result Method of results averaging Number of averaged values 5 ms Over the number of results 1 The parameters are stored in non-volatile memory of the sensor. Correct changing of the parameters is carried out using the parameterization program supplied with the sensor or the user program. The RS232 port provides a "point-to-point" connection and allows the sensor to be connected directly to RS232 port of a computer or controller. In accordance with the accepted network protocol and hardware capabilities, the RS485 port makes it...
