Features A Sensor with Stainless Steel Housing That's Strong, Compact, and Easy to Use! Resists Oils and Coolants Industry Top The E3ZM-C features a simple shape and structure, and yet provides IP67 protection and oil resistance (oil resistant to OMRON in-house standard). This performance exceeds any previous models from OMRON. The protective structure eliminates the need for screws to hold a cover, so there are no worries about loose screws leading to liquid penetration. The compact, easy-to-use E3ZM-C with built-in amplifier is ideal for oily environments. Insulation resistance (M) Comparison Example for Oil Resistance (Test Oil: Gryton 1700D) And the model number is laser-marked on the housing so it's always readable when the time comes to order maintenance parts. 1,000 100 E3ZM-C Previous metal sensor 10 0 50 100 150 200 250 300 350 400 Immersion time (h) E3ZM-C Laser Marking 1 E3ZM-C Industry Top Perfectly Reliable Detection Performance and Connection Method Visible Beam. Long-distance Operation Even in Dusty, Dirty Environments E3ZM-CT@2B Br ight Orange Spot The E3ZM-CT@2B uses a bright orange LED to generate a spot that's visible 1 m away. And the sensing distance of 20 m provides more leeway in detection (response time: 2 ms). It all adds up to a more visible, more dependable worksite. World's Smallest, and Yet Robust 1m Patent Pending The E3ZM-C is the same compact size as the E3Z, making it the smallest square metal photoelectric sensor in the world (according to OMRON investigation). The SUS316L housing makes it robust, and removes all worries of the coating coming off. Simple, Yet Dependable M12 Twist-andClick Pre-wired Connectors These Connectors match the XS5 Connectors released from August 2006, which reduce wiring work. They eliminate the troublesome need to control torque when tightening connectors, and remove worries about screws loosening due to vibration.

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. 11 E3ZM-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. (1) Locations subject to direct sunlight (2) Locations subject to condensation due to high humidity (3) Locations subject to corrosive gas (4) Locations where the Sensor may receive direct vibration or shock Connecting and Mounting (1) The maximum power supply voltage is 30 VDC. Before turning the power ON, make sure that the power supply voltage does not exceed the maximum voltage. (2) 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. (3) Use an extension cable with a minimum thickness of 0.3 mm2 and less than 100 m long. (4) 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 M3 screws. (6) Mount the Sensor either using the bracket (sold separately) or on a flat surface. (7) Be sure to turn OFF 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 100 ms after the power supply is tuned ON. Start using the Sensor 100 ms or more after turning ON the power supply. 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 shortcircuit protection circuit will be reset. The load short-circuit 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 (order separately) E39-L104 Use a mounting torque of 0.5 N*m max.
