A toothed washer must be used with the nut. This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Model E2CY-X1R5A Note: The above leeways in tighten torque assume that a toothed washer is being used. Precautions for Correct Use Do not use the product under ambient conditions that exceed the ratings. ● Design Influence of Surrounding Metal l d dia.

Dimpled end of 7 to 11.5 mm set screw (M3) When mounting the Sensor within a metal panel, ensure that the clearances given in the following table are maintained. Failure to maintain these distances may cause deterioration in the performance of the Sensor.

Do not remove the Sensor Head while the power supply is turned ON. If the E2CY-SD11 and load are connected to separate power supplies, always turn ON the power supply to the E2CY-SD11 first. Power OFF Output pulses may occur when the power supply is turned OFF. Turn OFF the power supply to the load or load line first. Teaching Mutual Interference When installing Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained.

Sensor cable (Unit: mm) *1 B Effects of a High-frequency Electromagnetic Field If the Sensor is located near a device that generates high frequencies or a transceiver, it may be affected by such a device and malfunctions may occur. Fast Moving Ferrous Metal At close range (50% or less of the sensing distance), iron and other ferrous metals may be detected if they are moving at high speed. If ferrous metals are present when objects are being detected at close range, make sure that the sensing objects move through the sensing range slowly (guideline: 20 ms or longer). 6 Make sure that the Sensor is in operating condition before making sensitivity adjustments. *1. Be sure to turn over the braided shield so that none of its thin wires are left. *2. Make sure that an insulation distance of at least 2.5 mm is maintained. 5 *2 2.5 4 to 5 7 to 8 14 max.
