Cylindrical Proximity Sensor E2A Safe Mounting with Greater Sensing Distance • Ensures a sensing distance approximately 1.5 to 2 times larger than that of any conventional OMRON Sensor. Problems such as the collision of workpieces are eliminated. Full range of standard si zes (M8, M12, M18 and M30; both long and short barrels) Modular construction simplifies customization. Please read and understand this catalog before purchasing the products. Please consult your OMRON representative if you have any questions or comments.

Power Supply Do not impose an excessive voltage on the E2A, otherwise it may be Connection with No Load damaged. Do not impose AC current (100 to 240 VAC) on any DC model, otherwise it may be damaged. Be sure to insert loads when wiring. Make sure to connect a proper load to the E2A in operation, otherwise it may damage internal ele- ments.

The E2A’s short-circuit protection function will be valid if the polarity of the supply voltage imposed is correct and within the rated voltage Do not disassemble, repair, or modify the product. range. ■ 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.

Mounting The Proximity Sensor must not be subjected to excessive shock with Environment a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose its water-resistivity. Water Resistivity Do not tighten the nut with excessive force. A washer must be used with the nut. 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.
