Transparent Object Detection Sensor Ideal for Detecting Glass Wafers and Other Transparent Objects • Detects glass wafers and LCD glass circuit boards. (Compact models with plastic housing only) Be sure to read Safety Precautions on page 7. Ordering Information Sensors Compact Models with Plastic Housing (Refer to Dimensions on page 8.) Model Sensing method Connection method Infrared light Recommended application *2 Flat object Cylindrical object Detecting plastic Detecting glass wafers bottles and other and LCD glass circuit transparent conboards tainers *1. Values in parentheses indicate the minimum required distance between the Sensor and Reflector. *2. The E3S-R may not detect some glass wafer materials or plastic bottle shapes. Before using the E3S-R, be sure to test it on samples to make sure it can detect the items reliably.

E3S-R Light Level Change Rates with Various Transparent Objects (*1) The following are the permeation rates of various transparent objects on condition that a permeation rate of 100 means that there is no object within the sensing distance of the E3S-R. 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.

E3S-R Safety Precautions Refer to Warranty and Limitations of Liability. 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. When the E3S-R senses an uneven plastic container or glass bottle,...
