Do not impose AC current (100 VAC) on any E2EM DC model, otherwise it may be damaged. When mounting the E2EM within a metal panel, ensure that the clearances given in the following table are maintained. Load Short-circuit Do not short-circuit the load, or the E2EM may be damaged. The E2EM's short-circuit protection function will be valid if the polarity of the supply voltage imposed is correct and within the rated voltage range. d dia. Wiring Be sure to wire the E2EM and load correctly, otherwise it may be damaged. Connection with No Load (Unit: mm) See note. Type E2EM E2EMXjXj DC 2-wire 2 wire Be sure to insert loads when wiring. Make sure to connect a proper load to the E2EM in operation, otherwise it may damage internal elements. Do not expose the product to flammable or explosive gases. Do not disassemble, repair, or modify the product. Shielded Unshielded J CORRECT USE Designing Power Reset Time The Proximity Sensor is ready to operate within 100 ms after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load.

Power OFF The Proximity Sensor may output a pulse signal when it is turned OFF. Therefore, it is recommended that the load be turned OFF before turning OFF the Proximity Sensor. Power Supply Transformer When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-transformer. AND/OR Connection When using the product in an AND/OR circuit, the product may not function properly due to incorrect pulses or leakage currents. Therefore, confirm that no problems will occur before actually using the product in such a circuit. 13 E2EM E2EM Mutual Interference J WIRING When installing two or more Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained. High-tension Lines Wiring through Metal Conduit: If there is a power or high-tension line near the cable of the Proximity Sensor, wire the cable through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning.

Check the operating voltage of the relay. Confirmation of Connection between DC 2-wire Proximity Sensor and Programmable Controller Cable Extension Connection conditions are determined from the relationship between the input ON voltage and OFF voltage of the PC and the output residual voltage and leakage current of the Proximity Sensor. DC 3-wire Models Cable length must be less than 200 m (656 ft.). The tractive force is 50 N (11.24 lbF). Connection to S3D2 Sensor Controller Operation can be reversed by selecting the signal input selector of the S3D2. Connection Conditions 1.

Relationship between the OFF voltage of the PC and the leakage current of the Proximity Sensor must be as follows: S3D2 VoffIleak x Rin Voff: OFF voltage of the PC Ileak : Leakage current of the Proximity Sensor Rin: Input impedance of the PC J MOUNTING The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose its water-resistivity. Connection is possible under the following conditions. Example values on the PC side ON voltage: 10.2 V min. OFF voltage: 3 V max. Input impedance: 3.5 k Example values on the Proximity Sensor side Output residual voltage: 5 V max. Leakage current: 0.8 mA max. If these values are put in the above formula, Von and Voff will be as follows: Von: 10.2 V<24 V-- 5 V (=19 V) Voff: 3 V>0.8 mA x 3.5 k (=2.8 V) Do not tighten the nut with excessive force.

Check for mounting position, dislocation, looseness, or distortion of the Proximity Sensor and sensing objects. 2. Check for loose wiring and connections, improper contacts, and line breakage. 3. Check for attachment or accumulation of metal powder or dust. 4. Check for abnormal temperature conditions and other environmental conditions. 5. Check for proper lighting of indicators (for models with a set indicator.) Never disassemble or repair the Sensor. J ENVIRONMENT Water Resistance Do not use the Proximity Sensor underwater, outdoors, or in the rain. Operating Environment Be sure to use the Proximity Sensor within its operating ambient temperature range and do not use the Proximity Sensor outdoors so that its reliability and life expectancy can be maintained. Although the Proximity Sensor is water resistive, a cover to protect the Proximity Sensor from water or water-soluble machining oil is recommended so that its reliability and life expectancy can be maintained. Do not use the Proximity Sensor in an environment with chemical gas (e.g., strong alkaline or acid gasses including nitric, chromic, and concentrated sulfuric acid gases). J CONNECTING LOAD TO DC 2-WIRE SENSOR Refer to the following before using DC 2-wire Proximity Sensors. Surge Protection Although the Proximity Sensor has a surge absorption circuit, if there is any machine that has a large surge current (e.g., a motor or welding machine) near the Proximity Sensor, connect a surge suppressor to the machine. E2EM Countermeasures Against Leakage Current Connect a bleeder resistor as the bypass for the leakage current so that the current flowing into the load will be less than the load reset current. Load Bleeder resistor R VS Refer to the following to calculate the bleeder resistance and the allowable power of the bleeder resistor. Leakage Current When the Proximity Sensor is OFF, the Proximity Sensor has leakage current. In this case, the load is imposed with a small voltage and the load may not be reset. Before using the Proximity Sensor, make sure that this voltage is less than the load reset voltage. R VS/(iR -- iOFF) (k) P > VS2/R (mW) P: The allowable power of the bleeder resistor. (The actual power capacity of the bleeder resistor must be at least a few times larger than the allowable power of the bleeder resistor.) iR: Leakage current of the Proximity Sensor (mA) iOFF: Load reset current (mA) It is recommended that 15 k max./450 mW min. for 12 VDC and 30 k max./0.1 W min. for 24 VDC be used. Inrush Current A load that has a large inrush current (e.g., a lamp or motor) will damage the Proximity Sensor, in which case connect the load to the Proximity Sensor through a relay.
