The permeation rate of any type of object sensed by the E3S-R must be as low as possible for reliable detection of the object. Before using the E3S-R, be sure to test it on samples to make sure it can detect the items reliably.

WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Precautions for Correct Use Do not use the product in atmospheres or environments that exceed product ratings. Adjusting * When the E3S-R senses a cylindrical object, the amount of light received varies with the direction of the cylindrical object. To prevent this, locate the E3S-R as shown in the following illustration. Reflector * When the E3S-R senses an uneven plastic container or glass bottle, the amount of light received varies with the direction and sensing part of the plastic container or glass bottle. To prevent this, turn a sample of the plastic container or glass bottle to the best sensing position of the E3S-R to find and decide the optimum direction and sensing part, and then make the sensitivity adjustment. * In principle, sensing objects must pass through the center between the E3S-R and the reflector. Sensing objects must not be too close to the Reflector, otherwise sensing errors may result. * Unless otherwise indicated, the E39-R1 Reflector is required for transparent object detection. The Receiver may not receive any light and detection capability may decline with other Reflectors. 7 E3S-R (Unit: mm) Dimensions Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
