A load must be used when power is supplied to the sensor. Although there is short-circuit protection, a combination of a short circuit and wrong wiring can permanently damage the sensor. The LED operates normally during a load short circuit, so check the wiring if the output is wrong. Fasten connectors tightly by hand. 8

Length A (mm) 5 7. Influence of surrounding metal A Max. tightening torque (N m) A B Metal other than the target object surrounding the sensor may influence operating characteristics. Leave space between the sensor and surrounding metal as shown below. B B C C. Series connection (AND switching circuit) When connecting two or more proximity sensors in series, erroneous output ( to ms) may occur without the rated current being supplied to each of the sensors. For this reason, series connection of proximity sensors is not recommended. However, if proximity sensors must be connected in series, a resistor of kω must be put in parallel to each of the sensors. Note that the maximum leakage current in a series connection will be.5ma. Operation lag also will occur, resulting in increased voltage drop, and the operation lamp will not light. Operation lag = ms x (No. of sensors in series - ) Voltage drop = Voltage drop of single sensor x No. of sensors in series. Parallel connection (OR switching circuit) If two or more proximity sensors are connected in parallel, total leakage current increases according to the following formula, and may result in the load not turning OFF. (Leakage current = Leakage current of single sensor x No. of sensors in parallel) When two or more sensors in parallel turn ON, one (or more) of A Shaded areas indicate surrounding metal other than the target object. A: Distance from sensing face of proximity sensor to mounting surface B: Distance from surface of iron plate to sensing face of proximity sensor. C: Distance from surface of iron plate to center of proximity switch when A= FL7M- 6H FL7M- 6H FL7M-7 6H FL7M- 6 A(mm) B(mm) C(mm) When mounting proximity sensors either parallel to or facing each other, mutual interference may cause the sensor to malfunction. Maintain at least the distances indicated in the figures below. Facing each other A. Mutual interference prevention Parallel Relay loads The voltage drop of these FL7M sensors is.v. Pay attention to this voltage drop when using a relay load. (With Vdc relays, switching is not possible.) 6. Operation upon power ON After the power is turned ON, it takes at most ms until the proximity sensor is ready for sensing. If the load and the proximity sensor use different power supplies, be sure to turn the proximity sensor ON before turning the load ON. 7. Influence of leakage current A minimal current flows as leakage current for operating the circuits even when the proximity sensor is OFF. Keep this in mind when turning off connected loads. 8. Minimum cable bend radius (R) The minimum bend radius (R) of the cable is times the cable diameter. Take care not to bend the cable beyond this radius. Also, do not excessively bend the cable within mm of the cable lead-in port. B
