SIZE OF TARGET DETECTING DISTANCE VS. MATERIAL OF TARGET Material Detecting distances Mild steel 15 mm (0.59 in) Stainless steel 10 mm (0.39 in) Brass 6.4 mm (0.25 in) Aluminum 5 mm (0.20 in) Copper 5 mm (0.20 in) Note: Standard target size is 30 x 30 x 1 mm. Note: If the target is a nonferrous metal, the operating distance of the proximity sensor decreases. However, with a piece of foil measuring about 0.01 mm (0.0004 in) in thickness, the detecting distance is equivalent to that with a ferrous metal. Note that the proximity sensor cannot detect extremely thin evaporated films and non-conductive targets. RESIDUAL LOAD VOLTAGE CHARACTERISTICS AC Switching Types TL-YS15MY -US 110 VAC 220 VAC Note: When the current rating of the load is less than 10 mA, false operation may occur. This is normal, and the problem can be solved by installing a bleeder resistor in parallel with the load. Use the formulas given here to calculate the power rating and value of the resistor. R < Vs (k) = 10 - i 2 P > Vs (mW) R P : Wattage of bleeder resistor i : Load current (mA) Vs : Supply voltage (V) 4 TL-YS TL-YS LEAKAGE CURRENT CHARACTERISTICS AC Switching Types TL-YS15MY -US Note: Even when the proximity sensor is in the OFF state, a very small amount of current flows to operate the internal circuit of the sensor. Because of this leakage current, a small voltage is generated in the load, which may occasionally result in improper resetting of the load. Before using the proximity sensor, confirm that this voltage is less than the release voltage value of the load. Dimensions Unit: mm (inch) 5 TL-YS TL-YS Precautions EFFECTS OF SURROUNDING METALS When mounting a proximity sensor flush with a metallic panel, be sure to provide a minimum distance as shown in the table to prevent the sensor from being effected by metallic objects other than the target. Drawing dimension Minimum distance mm (inch) A 45 (1.77) B 45 (1.77) MUTUAL INTERFERENCE To prevent mutual interference, be sure to space the sensors at a distance greater than that shown in the table below.
