(under load current of 100 mA with cable length of 1 m) 50 M min. (at 500 VDC) between current carrying parts and case 1,000 VAC, 50/60 Hz for 1 minute between current carrying parts and case Destruction: 10 to 55 Hz, 1.5 mm double amplitude for 2 hrs each in X,Y and Z directions Destruction: 500 m/s2 (approx. 50G) for 3 times each in X, Y and Z directions IEC144 IP50 Approx. 5.5 g Sensing Surface: PBT resin Rear cover: ABS resin Supply voltage (operating voltage) Current consumption Detectable object Sensing distance Differential travel Response frequency (see note 2) Operation Control output Indicators Ambient temperature Ambient humidity Temperature influence (see note 3) Voltage influence (see note 4) Residual voltage Insulation resistance Dielectric strength Vibration resistance Shock resistance Enclosure rating Weight Material Setting distance (standard object) (see note 1) 0 to 3.4 mm (iron, 18 x 18 x 1 mm) Note: 1. 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%. Engineering Data 2 E2R-A01 E2R-A01 Operation Output Circuit Diagram Timing Chart Dimensions Unit: mm (inch) E2R-A01 E22-01 3 E2R-A01 E2R-A01 Precautions Effects of Surrounding Metal If there is any metal near the sensor, the metal may effect the performance of the E2R or the temperature of the metal may effect the sensing distance of the E2R. Make sure that the clearances given in the following illustrations are maintained for accurate sensing operation. Handling and Connections 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.
