WARNING Connection with No Load This product is not designed or rated for ensuring safety of persons. Do not it for such purposes. Be sure to insert a load when wiring. Make sure to connect a proper load to the E2A3 during operation, otherwise it may damage internal elements. Power Supply Do not impose an excessive voltage on the E2A3, otherwise it may be damaged. Do not impose AC current (100 to 240 VAC) on any DC Model, otherwise it may be damaged. Load Short-circuit Do not expose the product to flammable or explosive gases. Do not disassemble, repair, or modify the product. Do not short-circuit the load, or the E2A3 may be damaged. The E2A3’s short-circuit protection function will be valid if the polarity of the supply voltage is correct and within the rated voltage range. Precautions for Correct Use Power OFF Designing 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. The Proximity Sensor is ready to operate within 100 ms after power is supplied. If separate power supplies are connected to the Proximity Sensor and load, be sure to supply power to the Proximity Sensor before supplying power to the load. Effects of Surrounding Metal When mounting the E2A3 within a metal panel, ensure that the clearances given in the following tables are maintained. 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. Mutual Interference 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.

Nut provided with E2A3 l = 0 mm E2A3 D-43 Wiring Maintenance and Inspection High-tension Lines Periodically perform the following checks to ensure stable operation of the Proximity Sensor over a long period of time. 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. Cable Extension The standard cable length is less than 200 m. The tractive force is 50 N. 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-resistance. Do not tighten the nut with excessive force. A washer must be used with the nut. 1. 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 attempt to disassemble or repair the Sensor. Environment Water Resistivity The Proximity Sensors are tested intensively on water resistance, but to ensure maximum performance and life expectancy, avoid immersion in water and provide protection from rain or snow. Operating Environment Store and operate the Proximity Sensor only within the given specifications. M8 Type Stainless Steel Model Brass Model M12 M18 M30 Torque 9 N·m --20 N·m 60 N·m 150 N·m Inrush Current A load that has a large inrush current (e.g., a lamp or motor) will damage the Proximity Sensor. Connect the load to the Proximity Sensor through a relay.
