1 Oil-resistant, Robust, Compact Photoelectric Sensor EZM-C CSM_EZM-C_DS_E 9 Photoelectric Sensor for the Automotive and Machine Tool Industries Oil-resistant, rugged body made of stainless steel. Spot visibility improved to as far as m away. Product lineup includes Through-beam Models with Orange Spot. Product lineup includes M Smartclick pre-wired connector models. Refer to Safety Precautions on page. For the most recent information on models that have been certified for safety standards, refer to your OMR website. Features Industry Top A Sensor with Stainless Steel Housing That's Strong, Compact, and Easy to Use! Resists Oils and Coolants The EZM-C features a simple shape and structure, and yet provides IP67 protection and oil resistance (oil resistant to OMR in-house standard). This performance exceeds any previous models from OMR. The protective structure eliminates the need for screws to hold a cover, so there are no worries about loose screws leading to liquid penetration. And the model number is laser-marked on the housing so it's always readable when the time comes to order maintenance parts. The compact, easy-to-use EZM-C with built-in amplifier is ideal for oily environments.

2 EZM-C Industry Top Perfectly Reliable Detection Performance and Connection Method Visible Beam. Long-distance Operation Even in Dusty, Dirty Environments The uses a bright orange LED to generate a spot that's visible m away. And the sensing distance of m provides more leeway in detection (response time: ms). It all adds up to a more visible, more dependable worksite. EZM-CT@B Bright Orange Spot m World's Smallest, and et Robust Patent Pending The EZM-C is the same compact size as the EZ, making it the smallest square metal photoelectric sensor in the world (according to OMR investigation). The SUS6L housing makes it robust, and removes all worries of the coating coming off. EZM-C EZ Simple, et Dependable M Twist-and- Click Pre-wired Connectors These Connectors match the S5 Connectors released from August 6, which reduce wiring work. They eliminate the troublesome need to control torque when tightening connectors, and remove worries about screws loosening due to vibration. EZM-C@@@-MTJ Locks with a /8th Turn Insert completely. "Click" Twist /8 th turn. Unique Miniaturization and Modularization Technologies Sensing Module The optical system and signal processing are all contained in one module, providing all the main functions required of a Photoelectric Sensor. Optical System Maximizes manufacturing technology, including sophisticated inline optical axis adjustment. Internal Structure Signal Processing Leading-edge technology for stabilization and miniaturization is obvious in the photo IC, which includes an external light interference prevention algorithm, CSP* mounting, and other components. *Chip Scale Package Cross Section Application Precaution Use the EZM-T/-R/-D/-LS in food processing or beverage filling applications where cleaners or disinfectants are present.

11 Safety Precautions Refer to Warranty and Limitations of Liability. WARNING This product is not designed or rated for directly or indirectly 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 high-pressure 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. EZM-C 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. Be sure to tighten the connector lock by hand; do not use pliers or other tools. 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.9 to.9 N m for M metal connectors and. to. N m for M8 metal connectors. Load 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. Environments with Cleaners and Disinfectants (e.g., Food Processing Lines) Do not use the Sensor in environments subject to cleaners and disinfectants. They may reduce the degree of protection. 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. Surface Temperature Burn injury may occur. The Sensor surface temperature rises depending on application conditions, such as the ambient temperature and the power supply voltage. Use caution when operating or performing maintenance on the Sensor.

12 EZM-C Precautions for Correct Use Do not use the Sensor in any atmosphere or environment that exceeds the ratings. 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 highvoltage 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 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. 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, so check the wiring before turning the power supply again. The shortcircuit protection circuit will be reset. The load short-circuit protection will operate when the current flow reaches.8 times the rated load current. When using a capacitive load, use an inrush current of.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 Oil Resistance The Sensor has passed oil resistance testing for the oils listed in the following table. Use this table as a guide when considering lubricants and cutting oils. Test oil type Lubricants Use a mounting torque of.5 N m max.
