Refers to the distance from the detecting surface to the passing position of the detectable object which permits positive detection even when the sensing detecting surface is decreased due to temperature or voltage fluctuation. 2. The response frequencies for DC switching are average values measured on condition that the distance between each sensing object is twice as large as the size of the standard object and the sensing distance set is half of the maximum sensing distance. 3. Refers to a change in detecting distance when the ambient operating temperature changes within Omron’s specified range and is expressed as the rate of variation (in percentage) with the detecting distance at the rated voltage taken as 100%. 4. Refers to a change in detecting distance when the supply voltage changes within a permissible range and is expressed as the rate of variation (in percentage) with the detecting distance at the rated voltage taken as 100%.

Make sure that the clearances given in the following illustrations are maintained for accurate sensing operation. The E2R incorporates a connector. Do not solder connector pins to lead wires. Use the E22-01 Connector or Molex connector (housing 010308033 and terminal 008700057) or Japan Molex connector (housing 5209-03 and terminal 5103). Do not impose external force on the terminal as shown in the following illustration or else the terminal may be damaged. Do not connect or disconnect the connector with the E2R turned on as the E2R may be damaged. Power Supply When using a standard switching regulator with the E2R, ground the frame ground (FG) and ground (G) terminals of the switching regulator for stable operation. Mutual Interference When installing two or more E2R units face to face or side by side, make sure that the minimum distances given in the following illustration is maintained.
