- *1. Use the yellow indicator on D1 Models as a guide. 

- *2. The response frequency is an average value. 

Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object, and a set distance of half the sensing distance. 

*3. The residual voltage of each E2EH-X@D@ DC 2-Wire Model is 5 V. When connecting to a device, make sure that the device can withstand the residual voltage. (Refer to page 9.) 

- *4. Operation with power supplied for 1,000 h has been verified at 110°C. Do not bend the cable repeatedly at 100°C or higher. 

- *5. IP69K Degree of Protection Specification 

IP69K is a protection standard against high temperature and high-pressure water defined in the German standard DIN 40050, Part 9. The test piece is sprayed with water at 80°C at a water pressure of 80 to 100 BAR using a specified nozzle shape at a rate of 14 to 16 liters/min. 

° The distance between the test piece and nozzle is 10 to 15 cm, and water is sprayed horizontally for 30 seconds each at 0 , 

30°, 60°, and 90° while rotating the test piece on a horizontal plane.

## **AND/OR Connections** 

Error pulses and leakage current may prevent application in AND or OR circuits. Always confirm operation in advance to confirm if there are any problems in operation. 

## **Mutual Interference** 

When installing Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained.

## **Connecting a DC 2-wire Proximity Sensor to a PLC (Programmable Controller) Required Conditions Example** 

Connection to a PLC is possible if the specifications of the PLC and the Proximity Sensor satisfy the following conditions. (The meanings of the symbols are given at the right.) 

1. The ON voltage of the PLC and the residual voltage of the Proximity Sensor must satisfy the following. VON ≤ VCC - VR 

2. The OFF current of the PLC and the leakage current of the Proximity Sensor must satisfy the following. 

In this example, the above conditions are checked when the Proximity Sensor is the E2EH-X7D1-T and the power supply voltage is 24 V. 

      1. VON (14.4 V) ≤ VCC (20.4 V) - VR (5 V) = 15.4 V: OK 

      2. IOFF (1.3 mA) ≥ Ileak (0.8 mA): OK 

      3. ION = [VCC (20.4 V) - VR (5 V) - VPC (4 V)] / RIN (3 k Ω ) ≅ Approx. 3.8 mA 

      - Therefore, IOUT (min.) (3 mA) ≤ ION (3.8 mA): OK Connection is thus possible. 

   - IOFF ≥ Ileak 

   - (If the OFF current is not listed in the PLC’s input specifications, take it to be 1.3 mA.) 

3. The ON current of the PLC and the control output of the Proximity Sensor must satisfy the following. IOUT (min.) ≤ ION ≤ IOUT (max.) 

- The ON current will vary, however, with the power supply voltage and the input impedance, as shown in the following equation. ION = (VCC - VR - VPC) / RIN
