Photoelectric Sensor with Built-in Amplifier (Oil Resistant) E3Z-K 3 Oil Resistance • Although the E3Z-###K Sensors have oil-resistant specifications, performance may be affected by certain types of oil. Refer to the table on the right. • E3Z-###K Sensors are tested for resistance to the oils given in the table on the right. Refer to the information in the table when deciding which type of oil to use. Testing oil classification JIS classification Product name Velocity No. 3 Dynamic viscosity (mm2/s) at 40 °C Lubricant --- Water insoluble coolant Class 2, No.5 Daphne Cut No less than 10 to AS-30D less than 50 Class 2, No.11 2.02 pH --- Yushiron Less than 10 Oil No. 2 ac Water soluble Class W1, coolant No. 1 Yushiroken --EC50T-3 7 to 9.5 Yushiron Lubic HWC68 7 to 9.9 Class W1, No. 2 Gryton 1700D 7 to 9.2 Class W2 , No. 1 Yushiroken S50N 7 to 9.8 Note 1. The E3Z-###K maintained a minimum insulation resistance of 100 MΩ after the sensors were dripped in all the above oils for 240 hours. 2. When using the Sensors in environments subject to oils other than those listed above, use the figures for kinetic viscosity and pH as rough guides. Consideration of the effects of additives in the oil may also be required. 3.

Connections ■ Wiring M8 Metal Connector Do not short-circuit the load, otherwise the Sensor may be damaged. • Be sure to connect or disconnect the metal connector after turning OFF the Sensor. • Hold the connector cover to connect or disconnect the metal connector. • Secure the connector cover by hand. Do not use any pliers, otherwise the connector may be damaged. • The proper tightening torque range is between 0.3 and 0.4 N • m. Be sure to tighten the connector securely, otherwise the specified degree of protection may not be maintained or the connector may be disconnected due to vibration. Wiring Mistakes Mounting Do not make mistakes in wiring, such as mistakes in polarity, otherwise the Sensor may be damaged. Sensor Mounting Connection without Load Use M3 screws to mount the sensor and tighten each screw to a maximum torque of 0.5 N • m. Power Supply Voltage Make sure that the power supply to the Sensor is within the rated voltage range and do not apply 100 VAC or more if the Sensor is a DC model, or otherwise the Sensor may explode or burn. Load Short-circuiting Do not connect power supply to the Sensor with no load connected, otherwise the internal elements may explode or burn. Operating Environment Do not use the Sensor in locations with explosive or flammable gas. ■ Precautions for Safe Use E3Z-@@@ E39-L104 Mounting Bracket (sold separately) Settings Power Reset Time The Sensor is ready to operate 100 ms after the Sensor is turned ON. If the load and Sensor are connected to independent power supplies respectively, be sure to turn ON the Sensor before turning the load ON. Photoelectric Sensor with Built-in Amplifier (Oil Resistant) E3Z-K 11 ■ Precautions for Safe Use Sensors The sensor has a special coating that makes it more oil resistant. Handle it with care to avoid scratching the coating. If you attach adhesive tape to the sensor, the coating may be damaged when you remove the tape. Part of the coating around the adjuster may peel off when you adjust the sensitivity. This does not reduce the oil resistance of the sensor. Cables Part of the cable is coated and may wrinkle when bent. Observe the following precautions when handling the cable because it is made of the same polyvinyl chloride (PVC) material as the cables for standard E3Z sensors. • Keep the cable from direct contact with oil. If the cable is used in oily environments, provide a cover or other protective measure to keep the cable from direct contact with oil. • Do not subject the cable to mechanical movements in oily environments. The sheath will lose its elasticity and harden over time. The cable may break as a result and cause faulty operation, or there may be damage to the sheath that leads to a short circuit. Lens The oil-resistant treatment on the lens may cause slight blurring, but this does not affect detection. 12 Photoelectric Sensor with Built-in Amplifier (Oil Resistant) E3Z-K Certain Terms and Conditions of Sale 1.
