Smart Sensor (Wide Laser Beam CCD Measurement Sensor) ZX-GT CSM_ZX-GT_DS_E_1_2 Achieves Micron Accuracy with Longest-in-Class Sensing Distance • Maximum sensing distance of 500 mm and measuring width of 28 mm provide a wide area. • 10-μm accuracy anywhere within the area, even though the sensor uses a non-contact method. • Stable detection of even transparent glass and mirror surfaces. • Compact sensor and controller provide minimal installation space requirements. Refer to Safety Precautions on page 8. For the most recent information on models that have been certified for safety standards, refer to your OMRON website. Features Maximum 500-mm area Measurable at any position Measurements can be consistently taken within a wide area, whatever stage the work is at or whichever way it is inserted. It can now be set to positions without interference from the work feed and without limitations of size of work area. Maximum 500-mm area Accurate! 10-μm by non-contact method ZX-GT is the only sensor with the ability to measure and locate position to an accuracy of 10 μm without contact. Unlike conventional through-beam laser sensors, the ZX-GT’s unique algorithm has the flexibility to meet a wide variety of applications, including the ability to accurately measure glass and mirror surfaces. Small! Compact like palm-top Compact sensor head that can be set in the gap between equipment. New concept “TRIO” Its compact controller is a continuation of the ZX series. 1/7 in speed compared with conventional products With OMRONS unique TRIO (Triple parallel processing) algorithm, it is possible to take 2000 high-speed samples per second, 7 times greater than previously possible, greatly reducing tact time.

However, be sure to limit the total extension cable length between the receiver and the Controller to 30 meters (including the receiver cable). 2 ZX-GT Leading Technology and CCD Processing Algorithm That Support Stable Measurements Thoroughly eliminating the effect of the ambient temperature Fluctuation in measurement values Measurement It is important to eliminate the influence of temperature to ensure the accuracy of a measurement. However, the temperature in the field environment changes according to the time and the season. With the ZX-GT, which employs CCD method, the influence on the resolution from temperature changes is greatly reduced leading to an error rate as low as 0.01% (2.8 micro-meters *). PD method (legacy method) * This is a representative case. Please see the specifications table for the details of the relevant conditions. CCD method Consistent measurement achieved even with variation in temperature Hot Transparent object detection possible Cold Integrated MRC filter The detection of edges has been a problem for transparent objects with traditional transmission type sensors. However, ZX-GT adopts OMRON’s unique MRC filter * (Mirror Reflection Cut Filter) and CCD methodology. It can accurately detect work that reflects light such as mirror-finished surface or work that allows light to pass through such as glass (including coated glass). * MRC Filter: OMRON’s proprietary optical filter. Even effective with mirror finished surfaces Edge Glass CCD Glass-edge measurement CCD elements detects a slight shadow created when a laser light hits the edge of the glass to determine the position of the edge. Sub-pixel processing Collimate optical technology Super parallel-beam CCD processing algorithm With OMRON’s unique collimate optical technology *, the closest to ideal parallel beam is created. Errors are controlled in the measurement area and the longest and most accurate measurement is achieved. CCD detects the shadow made from measurement objects and by performing sub-pixel calculation, it achieves 10 micrometer level accuracy. Collimator lens Mirror Laser * Collimate optical technology Collimate optical technology allows laser lights to stay parallel using mirror reflection and lens refraction effects, to take advantage of the laser light’s high-level of directivity. Measurement accuracy is within 10 micrometers CCD pixel pitch 3 ZX-GT New Concept “Smart Recipe” Using the PC software 'Smart-monitor GT', set up is easy with simply clicking the icons. This is OMRON’s Smart Recipe methodology. Easy to set-up Different features are organized by Interface Unit tabs, to allow the user to understand and change the settings easily. Controller By connecting it to the controller, RS-232C communication and binary output is possible. Measurement conditions can be saved on PCs. Advanced support for data collection and analysis The measurement data is gathered in the PCs in real time so it is easy to ascertain and analyse the current conditions at any time. ●Grasp the data trend and prevent defective parts ●Measurement result can be logged at appropriate times Time The trend of the measurement data and sudden change can be checked in the time-dependent graph, so that the appropriate action can be taken before defective goods are produced. The logged data can be sent to Excel . It is useful for traceability management and for preparing quality assurance reports. 4 ZX-GT Easy to use, even from a distance First in the industry 3-way optical axis adjustment Three optical axis adjustment functions are integrated for the industry’s longest measurement. This function provides the optimal adjustment when the sensor head is installed on-site. With the sensor-head With the controller LED on the light-receiving device is lit up to indicate when the light axis is matched. The CCD light reception balance is displayed in the upper display and the amount of light received can be confirmed with numerical values underneath. Longest in the industry With the PC The direction of the sensor head’s adjustment is graphically displayed. The adjustment conditions can be confirmed through the shapes of the light reception waveforms. 30-m cable extension The emitter and receiver do not need to be connected with each other. Each cable can be extended up to 30 m. It is perfectly suited for installation into large-scale production line. 30 m to 24 VDC Receiver maximum length 30 m (using the special extension cables) Controller Emitter maximum length 30 m to 24 VDC 5 ZX-GT Ratings and Specifications Sensor Head Item Model ZX-GT28S11 ZX-GT28S41 ZX-GT2840S11 ZX-GT2840S41 Output type NPN Appearance Separate type PNP Light source Visible semiconductor laser diode (wavelength 650 nm, CLASS 1 of EN60825-1/IEC60825-1, CLASS II of FDA (21CFR 1040.10 and 1040.11) Measuring width 28 mm Sensing distance 0 to 500 mm 40 mm 0 to 500 mm 40 mm Minimum sensing object 0.5 mm dia. *1 0.2 mm dia. 0.5 mm dia. *1 0.2 mm dia.

A simple average is used in IC lead pitch judgment mode or IC lead width judgment mode. The measurement cycle time can be calculated as follows: Specified measurement cycle time × (Number of samples to average + 1) + 1 ms max. In other measurement modes, a moving average is used. The first measurement cycle time can be calculated as follows: Specified measurement cycle time × (Number of samples to average + 1) + 1 ms max. The second and later measurement cycle times will be equal to the specified measurement cycle time. *2.

Current/voltage can be switched using the switch provided on the rear of the Controller. Can be set by the analog output scaling function. The error (ERR) state is displayed when all HIGH/PASS/LOW outputs turn OFF. Normally, wire the sync output wire directly to the emitter’s sync input wire and run the Controller in the standard mode. On an NPN type Controller, use an NPN type emitter, and on a PNP type Controller, use a PNP type emitter. Wiring of the sync wires is not required when the Controller is run in the high-speed mode. (Note, however, that the Controller becomes more susceptible to the influence of ambient light in this case.) *7. The value is 175 mA max. (including receiver) when current output is set.
