1 Compact Photoelectric Sensor with Stainless Steel Housing EZM CSM_EZM_DS_E_5_8 Stainless Steel Housing Ideal for Food Industry PAT Pending Strong resistance against detergents, disinfectants, and jet liquid flow. Product lineup includes and Through-beam Models with built-in slits. Certified by Ecolab Europe. Be sure to read Safety Precautions on page. For the most recent information on models that have been certified for safety standards, refer to your OMR website. Features World's Strongest Withstands Detergent and Disinfectant Spray We used SUS6L for the case and the best material for all parts to achieve times the durability of the EZ (in.5% solution of sodium hydroxide at 7 C) to make the EZM suitable for the cleaning conditions of food-processing machinery. World's First Superior Protective Structure Industry's Best The first IP69K* (DIN 5-9) protective structure in the world for a square metal photoelectric sensor. Suitable for hightemperature, high-pressure jet water spray cleaning applications. * Refer to the footnote on page 5 (ratings and specifications table). Shape and Markings Designed for Greater Hygiene Few indentations in the shape means less dust and water can collect, making the EZM more hygienic. No labels have been used in order to prevent foreign matter contaminating food products. The EZM model and lot numbers are imprinted using a laser marker. Rear

2 *short description EZM Structural Design That Provides Excellent Environment-resistance* Indicator cover: Polyetherimide (PEI) Excellent resistance to detergents and disinfectants. Waterproofing ring: Fluorine rubber Excellent resistance to detergents and disinfectants. Optical plate: Polymethylmethacrylate (PMMA) Excellent resistance to detergents and disinfectants. High transparency and other qualities give PMMA excellent optical characteristics. Seal The seal provides the durability to high-temperature and high-pressure water that complies with IP69K. *Do not use the EZM in an oily environment. Unique Members of the EZM Family Three models with different fixed sensitivity (rated sensing distances) have been created. These models cover the sensing ranges of the EZ- LS6. Sensitivity adjustment and mode selector switch: Polyetheretherketone (PEEK) Excellent resistance to detergents and disinfectants. Also has excellent abrasion resistance. Case: SUS6L Excellent corrosion resistance to many chemical reagents. Cable: Polyvinylchloride Excellent resistance to detergents and disinfectants. mm 5mm mm Through-beam Inner Aperture Models EZM-T6 Fine beam without attaching an external aperture. This eliminates malfunctions from residual water drops, even immediately after washing. A Better Fit for the Application The EZM can be used in those harsh cleaning environments in which the EZ was difficult to use. EZM passed the material resistance tests and is certified by Ecolab.

13 Safety Precautions Refer to Warranty and Limitations of Liability. WARNING This product is not designed or rated for ensuring safety of persons. Do not use it for such a purpose. CAUTI Do not use the product with voltage in excess of the rated voltage. Excess voltage may result in malfunction or fire. Never use the product with an AC power supply. Otherwise, explosion may result. When cleaning the product, do not apply a concentrated spray of water to one part of the product. Otherwise, parts may become damaged and the degree of protection may be degraded. High-temperature environments may result in burn injury. Precautions for Safe Use The following precautions must be observed to ensure safe operation of the Sensor. Operating Environment Do not use the Sensor in an environment where explosive or flammable gas is present. Connecting Connectors Be sure to hold the connector cover when inserting or removing the connector. If the SF is used, always tighten the connector cover by hand. Do not use pliers. If the tightening is insufficient, the degree of protection will not be maintained and the Sensor may become loose due to vibration. The appropriate tightening torque is. to. N m. If other commercially available connectors are used, follow the recommended connector application conditions and recommended tightening torque specifications. EZM Do not use a load that exceeds the rated load. Low-temperature Environments Do not touch the metal surface with your bare hands when the temperature is low. Touching the surface may result in a cold burn. Rotation Torque for Sensitivity Adjustment and Selector Switch Adjust with a torque of.6 N m or less. Oily Environments Do not use the Sensor in oily environments. Modifications Do not attempt to disassemble, repair, or modify the Sensor. Outdoor Use Do not use the Sensor in locations subject to direct sunlight. Cleaning Do not use thinner, alcohol, or other organic solvents. Otherwise, the optical properties and degree of protection may be degraded. Washing Do not use highly concentrated detergents. They may cause malfunction. Do not use high-pressure water spray in excess of the specifications. Surface Temperature Burn injury may occur. The Sensor surface temperature rises depending on application conditions, such as the surrounding temperature and the power supply voltage. Use caution when operating or washing the Sensor.

14 EZM Precautions for Correct Use Do not install the Sensor in the following locations. ()Locations subject to direct sunlight ()Locations subject to condensation due to high humidity ()Locations subject to corrosive gas ()Locations where the Sensor may receive direct vibration or shock Connecting and Mounting ()The maximum power supply voltage is VDC. Before turning the power, make sure that the power supply voltage does not exceed the maximum voltage. ()Laying Sensor wiring in the same conduit or duct as high-voltage wires or power lines may result in malfunction or damage due to induction. As a general rule, wire the Sensor in a separate conduit or use shielded cable. ()Use an extension cable with a minimum thickness of. mm and less than m long. ()Do not pull on the cable with excessive force. (5)Pounding the Photoelectric Sensor with a hammer or other tool during mounting will impair water resistance. Also, use M screws. (6)Mount the Sensor either using the bracket (sold separately) or on a flat surface. (7)Be sure to turn the power supply before inserting or removing the connector. Cleaning Never use thinner or other solvents. Otherwise, the Sensor surface may be dissolved. Power Supply If a commercial switching regulator is used, ground the FG (frame ground) terminal. Power Supply Reset Time The Sensor will be able to detect objects ms after the power supply is tuned. Start using the Sensor ms or more after turning the power supply. If the load and the Sensor are connected to separate power supplies, be sure to turn the Sensor first. Turning the Power Supply Output pulses may be generated even when the power supply is. Therefore, it is recommended to first turn the power supply for the load or the load line. 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, so check the wiring before turning the power supply again. The short-circuit protection circuit will be reset. The load shortcircuit protection will operate when the current flow reaches.8 times the rated load current. When using a C load, use an inrush current of.8 times the rated load current or higher. Water Resistance Do not use the Sensor in water, rainfall, or outdoors. When disposing of the Sensor, treat it as industrial waste. Mounting Diagram Use a mounting torque of.5 N m max. Resistance to Detergents, Disinfectants, and Chemicals Performance is assured for typical detergents and disinfectants, but performance may not be maintained for some detergents and disinfectants. Refer to the following table when using these agents. The EZM passed testing for resistance to detergents and disinfectants performed using the items in the following table. Refer to this table when considering use of detergents and disinfectants. Category Chemical Alkaline foam detergent Acidic foam detergent Product name Mounting Bracket (sold separately) E9-L Concentration Temperature Time Sodium hydroxide (NaOH).5% 7 C h Potassium hydroxide (KOH).5% 7 C h Phosphoric acid (HPO).5% 7 C h Sodium hypochlorite (NaCIO).% 5 C h Hydrogen peroxide (HO) 6.5% 5 C h P-topax-66s (Manufactured by Ecolab).% 7 C h P-topax-56 (Manufactured by Ecolab) 5.% 7 C h P-oxonia active 9 (Manufactured by Ecolab).% 5 C h Disinfectant TEK (Manufactured by ABC Compounding).% 5 C h Note: The Sensor was immersed in the chemicals, detergents, and disinfectants listed above at the temperatures in the table for hours and then passed an insulation resistance of MΩ min.
