[. . . ] Stainless Steel Housing Oil-resistant, Robust, Compact Photoelectric Sensor with Built-in Amplifier E3ZM-C A New Photoelectric Sensor Designed for the Automotive and Machine Tool Industries Features 1 Oil-resistant, Robust, and Compact (IP67g Degree of Protection) 10. 8 21 SUS316L 32. 2 Oil-resistant PVC cable, 4-mm dia. 25. 4 Actual Size Two, M3 holes Features 2 A Through-beam Sensor with a Visible Spot for Easy Beam Adjustment Features 3 Twist-and-Click M12 Pre-wired Connector Only 1/8th Turn Locks the Connectors E3ZM-C P h o to e l e c t r i c S e n s o rs A New Sensor with Stainless Steel Housing That's Strong, Compact, and Easy to Use! Resists Oils and Coolants The E3ZM-C features a simple shape and structure that resist oils and coolants, performance that meets or 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. 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 E3ZM-C with built-in amplifier is ideal for oily environments.

[. . . ] 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. 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) (2) (3) (4) 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 (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 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. (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. (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. 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. Cleaning Never use thinner or other solvents. Otherwise, the Sensor surface may be dissolved. 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 0. 39 to 0. 49 N·m for M12 metal connectors and 0. 3 to 0. 4 N·m for M8 metal connectors. 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. 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. 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. Rotation Torque for Sensitivity Adjustment and Selector Switch Adjust with a torque of 0. 06 N·m or less. 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.
