HIGH RESOLUTION MEASUREMENT SENSORS • 80 ± 40 mm operating distance • Resolution reaching 8 µm • Linearity <0.1 % • Management of internal buffer memory • 0.5x0.75 mm spot at focus distance S62-Y SERIES The new S62-Y series of displacement sensors with class II Laser red emission and micrometric resolution is based on optic triangulation technology, offering very accurate distance measurement as well as precise thickness or position verification. The sensor especially suits applications with reduced space and offers a very low response time (<666 µs) with a very high measurement resolution reaching 8 µm. The PC connection using the RS485 serial protocol and graphic user interface make sensor configuration and data control very intuitive and easy. Typical applications are in the wood industry, metal working, positioning for assembly lines and pick and place. The series includes two different models, both with an additional alarm signal in case of low signal or dirty lenses. DISPLACEMENT SENSORS S62-Y SERIES The S62-Y sensor uses optical DIMENSIONS triangulation to determine the position of the target object: when the laser beam is reflected from the 50 object to the receiver, spot position 18 42 is digitally processed to calculate object position.

The software is available on the CD-ROM supplied with the product and includes an exhaustive on-line help. It operates in the Windows 2000/XP/Vista environment. Special features: • Management of several sensors at the same time • Measurement indicator with numeric and graphic display • Differential detection/reading comparison between pairs of sensors • Data plotting on time/distance XY graph (graph display may be turned on/off by user) • Graphic windows may be saved in image format • Acquired data may be saved in ASCII format • Data may be saved to a binary meta-format file • Event management and ASCII LOG file (alarms) • The graphic structure makes the software easy to control using a touch-screen display. STAND-ALONE MASTER/SLAVE FUNCTIONING Two S62-Y sensors are connected together in this mode and the analogue output of one (MASTER) supplies the thickness variation (differential measurement) of the objects that move between the sensors respect to a zero condition. The sensors can be installed even with overlapping measurement fields. The object must have the necessary thickness to guarantee that both sides are included in the measurement field of both sensors. Measurement range Note: the best performances are obtained when the object to measure is in the middle of the two measurement ranges. INSTALLATION Mount the two S62-Y sensors and connect as shown in the drawing. Set one of the two sensors in the MASTER mode. The MASTER sensor’s analogue output represents the differential measurement of the thickness of the moving object. In the reference condition, i.e. when an object with a thickness equal to the one detected during the set-up procedure, the analogue output of the MASTER sensor reaches the middle value of the range (about 5V in the PVZ version and about 12 mA in the PIZ version). The analogue output variations follow the thickness variation of the objects that pass respect to the reference condition. Note: - in the MASTER/SLAVE configuration, the two sensors can be indifferently PIZ or PVZ. If a PIZ version is connected to a PVZ version, the analogue output will supply the differential measurement in mA current if the PIZ sensor has been set as MASTER. Viceversa, the differential measurement will be in Vdc voltage if the PVZ has been set as MASTER; - the MASTER/SLAVE functioning requires a continuous query of the SLAVE sensor through the RS485 serial interface. Environmental disturbances can electrically jeopardize the communication bus and the communication between the two sensors can be disturbed; - the MASTER sensor can detect disturbances on the serial communication, signalling the condition with a red LED blinking during normal functioning. If the blinking is continuous, we suggest to power off the sensors, control the connections and re- power the system. S62-Y SERIES FUNCTIONS ACCESSIBLE VIA RS485 The S62-Y sensor features a standard industrial EIA/TIA-485 serial interface, also known as RS485. Half-duplex communication permits several sensors (up to 8) to be connected to the same bus at the same time. Besides permitting several reading modes for measured data, the serial interface allows the user to access the programming mode and many other auxiliary sensor functions. Each sensor on the RS485 bus is identified by an address. The default, factory-set address for all sensors is “000” and it is the user's responsibility to set a specific address for each sensor. Depending on whether the M/S bit identifies the transmission as coming from a MASTER element (command) or a SLAVE element (command response), the address identifies the packet receiver and source respectively. When implementing the bus connection as shown in the figure below, we recommend the user to maintain the RS485 connection between individual sensors and main bus as short as possible. For main line termination issues, please refer to the EIA/TIA-485 standard. MANAGEMENT OF INTERNAL BUFFER MEMORY The S62-Y sensor uses an internal buffer memory to save the measurement result when an external trigger event takes place (pulse on STORE pin). This function is very useful in applications that require STORE pulse measurement synchronisation amongst different sensors (e.g. line measurements with several devices positioned side by side Measurement line as shown in the figure). The size of the measurement storage buffer is 32 elements: This means 32 different measurements can be stored without losing data. The buffer operates on the FIFO principle. Once the 32 locations are occupied, the device will overwrite the oldest data. The buffer may be accessed or queried for valid data via the RS485 interface. Movement The sensor stores measurements on STORE pulse edge, rather than on the level. This will avoid time constraints for the user and prevent filling the storage capacity with unwanted measurement memorisations.
