Laser Triangulation Sensors. RF602 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“ category...

Laser Triangulation Sensors. RF602 Series 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 the 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. Connection Assignment of the cable wires is shown in the table below: Model of the sensor 232-U/I-IN-AL Pin number free...

Laser Triangulation Sensors. RF602 Series Configuration parameters The nature of operation of the sensor depends on its configuration parameters, which can be changed only by transmission of commands through serial port RS232 or RS485. The basic parameters are given below. Time limit for integration Intensity of the reflected radiation depends on the surface characteristics of the object under control. Therefore, the output power of the laser and the time of integration of radiation incident onto the CMOS array are automatically adjusted to achieve the maximum measurement accuracy. The "Time...

Laser Triangulation Sensors. RF602 Series Note 2. If the bit-serial interface is used to receive the result, the time required to transfer data at the selected data transmission rate should be taken into account when setting small intervals of the sampling period. If the transmission time exceeds the sampling period, then this time will determine the data transmission rate. The calculation of time required to transmit the result is given in par. 11.7.4. Note 3. It should be taken into account that the sensors differ in some variation of the parameters of the internal generator, which affects...

Laser Triangulation Sensors. RF602 Series Mutual synchronization Hardware zero-set/ Hardware laser ON/OFF Time lock of the result If the sensor does not find the object or if the authentic result cannot be received, a zero value is transferred. The given parameter sets time during which the last authentic result is transferred. Method of results averaging This parameter defines one of the two methods of averaging of measurement results implemented directly in the sensor: · Averaging over a number of results · Time averaging When averaging over a number of results is selected, sliding average...

Correct changing of the parameters is carried out by using the parameterization program supplied with the sensor or a user program. Data exchange with the sensor is carried out over...

Laser Triangulation Sensors. RF602 Series Configuration parameters Rate of data transfer through serial port This parameter defines the rate of data transmission via the bit-serial interface in increments of 2400 bit/s. For example, the parameter value equal to 4 gives the transmission rate of 2400*4 = 9600 bit/s. Note. The maximum transmission rate for RS232 and RS485 interfaces is 921,6 kbit/s. This parameter defines the network address of the sensor equipped with RS485 interface. Note. The network data communication protocol assumes the presence of a ‘master’ in the net, which can be a computer...

Laser Triangulation Sensors. RF602 Series 'Answer' is the data burst that can be transmitted by ‘slave’ in the course of the session. All messages with a message burst contain 1 in the most significant digit. Data in a message are transferred in tetrads. When byte is transmitted, lower tetrad goes first, and then follows higher tetrad. When multi-byte values are transferred, the transmission begins with lower byte. When ‘answer’ is transmitted, the message contains: · SB-bit, characterizes the updating of the result. If SB is equal to "1", this means that the sensor has updated the measurement...
