User manual OMRON E3ZM-V DATASHEET

[. . . ] Print mark detection photoelectric sensor in compact stainless steel housing E3ZM-V The detergent resistant photoelectric sensor in a robust stainless steel housing provides reliable detection of all common print marks in packaging applications. · White LED for stable detection of differently colored print marks · SUS 316L stainless steel housing · Easy-to-use teach-in button or remote dynamic teach · Fast response time of 50 µs Features Reliable print mark detection within OMRON's most popular E3Z sensor family The E3ZM-V provides reliable print mark detection in the compact sized E3Z housing. For packaging machine makers the E3Z family offers a complete sensor platform with one mounting concept simplifying installation and machine design. · Space-saving design with an SUS316L housing The compact design reduces volume by 90% compared to conventional mark sensors. · Coaxial optical system The coaxial optical system ensures stable detection of print marks on uneven surfaces. Straight Sensing Object RGB light-receiving element Half mirror E3ZM Standard Size Only 10% the volume! Conventional mark sensor size E3ZM-V Lens White LED Sensing object (with regular reflection) Inclined Sensing Object RGB light-receiving element Half mirror Lens White LED Sensing object (with regular reflection) E3ZM-V 1 Water and detergent resistance The housing is constructed of corrosion-resistant SUS316L, and the display cover is PES (polyethersulfone). Both materials are highly resistant to the corrosive effects of detergents and disinfectants. The IP69k tight housing construction ensures long sensor lifetime in often cleaned environments. Same Durability as the E3ZM Reliable detection of differently colored print marks due to RGB signal processing · RGB signal processing The white LED and RGB signal processing ensure the stable detection of differently colored print marks. [. . . ] If the load and the Sensor are connected to separate power supplies, be sure to turn ON the Sensor first. Turning OFF the Power Supply Output pulses may be generated even when the power supply is OFF. Therefore, it is recommended to first turn OFF the power supply for the load or the load line. Load Short-circuit Protection This Sensor is equipped with load short-circuit protection, but be sure to not short circuit the load. Be sure to not use an output current flow that exceeds the rated current. If a load short circuit occurs, the output will turn OFF, so check the wiring before turning ON the power supply again. The short-circuit protection circuit will be reset. The load shortcircuit protection will operate when the current flow reaches 1. 8 times the rated load current. When using a capacitive load, use an inrush current of 1. 8 times the rated load current or lower. Water Resistance Do not use the Sensor in water, rainfall, or outdoors. When disposing of the Sensor, treat it as industrial waste. Mounting Diagram Mounting Bracket (sold separately) Use a mounting torque of 0. 5 N·m max. E39-L104 Resistance to Detergents, Disinfectants, and Chemicals · The Sensor will maintain sufficient performance in typical detergents and disinfectants, but performance may suffer in some types of detergents, disinfectants, and chemicals. Refer to the following table prior to use. · The E3ZM has passed detergent and disinfectant resistance testing for the substances listed in the following table. Use this table as a guide when considering detergents and disinfectants. Type Chemicals Product name Sodium hydroxide, NaOH Potassium hydroxide, KOH Phosphoric acid, H3PO4 Hydrogen peroxide, H2O2 Alkaline foaming cleansers Acidic foaming cleansers Disinfectants Topax 66s (Ecolab) Concentration 1. 5% 1. 5% 2. 5% 6. 5% 3. 0% Temperature 70°C 70°C 70°C 25°C 25°C 70°C Time 240 h 240 h 240 h 240 h 240 h 240 h Sodium hypochlorite, NaClO 0. 3% Topax 56 (Ecolab) Oxonia Active 90 (Ecolab) TEK121 (ABC Compounding) 5. 0% 1. 0% 1. 1% 70°C 25°C 25°C 240 h 240 h 240 h Note: The Sensor was immersed in the above chemicals, detergents, and disinfectants for 240 h at the temperatures given, and then passed an insulation resistance test at 100 MW min. Restrictions on Sensing Objects Do not use this Sensor if the color and pattern of the background are similar to those of the mark. Detection of Glossy Objects Mount the Sensor at an angle of 5° to 15°, as shown in the following diagram. This will improve the mark detection capability. 5° to 15° 5° to 15° Sensing objects Sensing objects 8 Photoelectric Sensor Operating Procedure Two-point Teaching Using Teaching Button 1. Place the point for which you want the output to go ON in the beam spot position. Then, press and hold the teaching button for at least 2 seconds. Sensor Mark Background The teaching indicator (red) will begin flashing quickly. (This indicates that the output ON teaching operation should begin. ) Perform the following operation within 7 seconds of when you start pushing the button. (After 7 seconds, the Unit will return to its initial condition. ) Flashes quickly 2. Press the teaching button for approximately 0. 5 second.
