The Confocal Fiber Displacement Sensor that goes beyond triangulation concepts with a new principle. Displacement Sensors are indispensable The Three Benefits of OMRON’s White Light Confocal Principle in non-contact measurement of heights, thicknesses, and other dimensions in machine operation control. However, building them into the system has always presented problems. The Confocal Fiber Displacement ZW Series Sensor solves these problems in ways that were not The slim design measures only 24 × 24 mm. It weighs only 105 g. This incredibly compact size could not be achieved with...

Stable Measurements for Any Material with Superior Angle Characteristic Stable Measurements from the Same Mounting Position Even for Different Materials There is no need to change or tune the Sensor for each material. Even if the material changes, you can continue to achieve stable measurements with the same Sensor from the same mounting position. Regular-reflective workpiece Diffuse-reflective workpiece White ceramic Stable Measurements for Any Material to ±2 μm (with the ZW-S20) Traditional Triangulation Model ±5 μm or less Large discrepancy between materials. Linearity for Various...

Superior Angle Characteristic When measuring an object that has a mirror-like surface with traditional triangulation, performance is greatly reduced depending on the angle of the Sensor. When many Sensors are used for height control during glass conveyance, the angles of the Sensors must be adjusted with high precision during setup. The confocal Sensor ZW series enables high-resolution measurements without strict angle adjustment. This results in reduction of cost and space for the adjusting jig and time for adjustment. * This is not a guaranteed value. Refer to Characteristic Data (P17)...

Robust Sensor Head Structure Reduced Work for EMC Countermeasures Not Affected by Noise To ensure high-resolution measurements with normal sensors, countermeasures must be implemented to protect the sensor from the electromagnetic noise that is emitted by any nearby devices.The ZW-series Sensor Heads, however, contain no electronic parts to enable stable measurements even near power sections. Also, the Fiber Cable that connects the Sensor Head to the Controller can be placed near power lines and other cables that emit noise without affecting operation. Traditional Triangulation Model...

EtherCAT Machine Control Network High-speed Digital Output Shorter Machine Takt Times With previous digital (serial) outputs through Ethernet or RS-232C, the response period for measurement commands was both inconsistent and slow, making them unsuitable for realtime control. With EtherCAT, a constant period as short as 500 μs enables continuous digital (serial) outputs so that the overall workpiece height information can be mapped at high speed. Previous Serial Output The EtherCAT high-speed open network was optimized for machine control. The ZW-series Sensors are the first OMRON...
