Precautions Item Power Supply Do not impose an excessive voltage on the, otherwise it may explode or burn. Do not impose AC voltage on any DC model, otherwise it may explode or burn. Examples Incorrect Do not connect the AC types without load to the power supply. The sensor will be damaged. Correct Use Installation Power Reset Time The proximity sensor is ready to operate within 300 ms after power is supplied. If power supplies are conencted to the proximity sensor and load respectively, be sure to supply power to the proximity sensor before supplying power to the load. Power OFF The proximity sensor may output a pulse signal when it is turned off. Therefore, it is recommended to turn off the load before turning off the proximity sensor Sensing Object Metal Coating: The sensing distance of the proximity sensor vary with the metal coating on sensing objecs. Wiring High--tension lines Wiring through Metal Conduit If there is a power or high--tension line near the cable of the proximity sensor, wire the cable through an independent metal conduit to prevent against proximity sensor damage or mulfunctioning. Mounting The proximity sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the proximity sensor may be damaged or lose the water--resistivity. Environment Water--resistivity Do not use the proximity snesor in water, in the rain or outdoors. Operating Atmosphere To ensure stable operation and long sensor life, do not operate the proximity sensor outside the rated temperature range or in outside conditions. Although the proximity sensor has a water--resistive construction, reliability and product life can be further enhanced by installing a cover to prevent water splashing directly on the senosr. Avoid operating the proximity sensor in an atmosphere containing chemical reagents, strong alkalis or acids (nitric, chromic and concentrated sulfuric acid ). DC Type Connection Type Method Description AND (serial connection) The sensors connected together must satisfy the following conditions: i L + (N--1) x i < Upper--limit of control output of each sensor VS -- N x V > Load operating voltage R N = No. of sensors V = Residual voltage of each sensor R V S = Supply voltage i = Current consumption of the sensor i L = Load current If the MY relay, which operate at 24 VDC, is used as a load for example, a maximum of 2 proximity sensors can be connected to the load OR (parallel connection) A minimum of 3 sensors with current outputs can be connected in parallel. The number of sensors connected in parallel varies with the proxmity sensor model. 10

AC Type Connection Type Method Description AND (serial connection) If 100 or 200 VAC is imposed on the proximity sensors, V (i.e. the voltage imposed on the load) will be obtained from the following. V = V (residual voltage x no. of proximity L S sensors) (V) Therefore, if VL is lower than the load operating voltage, the load will not operate. A maximum of 3 proximity sensors can be connected in series provided that the supply voltage is 100 V minimum. OR (parallel connection) In principle, more than 2 proximity sensors cannot be connected in parallel. Provided that proximity sensor A does not operate with proximity sensor B simultaneously and there is no need to keep the load operating continuously, the proximity sensor can be conencted in parallel. In this case, however, due to the total leakage current of the proximity sensors, the load may not reset properly. It is not possible to keep the load operating continuously with proximity sensors A and B in simultaneous operation to sense sensing objects due to the following reason. When proximity sensor A is ON, the voltage imposed on proximity sensor A will drop to approximately 10 V and the load current flows into proximity sensor A, and when one of the sensing objects is close to proximity sensor B, proximity sensor B will not operate because the voltage imposed on proximity sensor B is 10 V, which is too low. When proximity sensor A is OFF, the voltage imposed on proximity sensor B will reach the supply voltage and proximity sensor B will be ON. Then, proximity sensor A as well as proximity sensor B will be OFF for approximately 10 ms, which resets the load for an instant. To prevent the instantaneous resetting of the load, use a relay as shown on the left. 11
