5 Connection DC type Connection type Method Description The s connected together must satisfy the following conditions: i L + (N-) x i Upper-limit of control output of each V S - N x V R operating voltage N = No. of s AND V R = Residual voltage of each (serial connection) V S = Supply voltage i = Current consumption of the i L = current If the MY Relay, which operate at 24 VDC, is used as a load for example, a maximum of two s can be connected to the load. OR (parallel connection) A minimum of three s with current outputs can be connected in parallel. The number of s connected in parallel varies with the model. Precautions! Caution Power supply Do not impose an exessive voltage on the E2Q2, otherwise it may explode or burn. Do not connect an AC power supply to any DC model. If AC power (00 VAC or more) is supplied to the sensor, it may explode or burn. Short-circuiting Do not short-circuit the load, otherwise the may be damaged. Connection without Do not connect the power supply to the with no load connected, otherwise the internal elements may explode or burn. Operating Environment Do not use the in locations with explosive or flammable gas. Be sure to abide by the following precautions for the safe operation of the. Wiring Power Supply Voltage and Output Power Supply Voltage Make sure that the power supply to the is within the rated voltage range. If a voltage exceeding the rated voltage range is supplied to the, it may explode or burn. 5

6 Correct Use Design Effects of Surrounding Metal Provide a minimum between the and the surrounding metal as shown in the table below. Effects of Surrounding Metal (Unit: mm) Model Length A B C -N20##-M N0M##-M N40M##-M Mutual Interference If more than one is located in parallel, ensure to maintain enough space between adjacent s to suppress mutual interference as provided in the following diagram. Mutual Interference (Unit: mm) Model Length A -N20##-M 40 -N0M##-M 20 -N40M##-M 50 A B C Side-by-side A metal coating on sensing objects. Wiring High-tension cables Wiring through Metal Conduit: If there is power or high-tension line near the cable of the, wire the cable through an independent metal conduit to prevent against damage or malfunction. Mounting Mounting the The must be subjected to excessive shock with a hammer when it is installed, otherwise the may be damaged or lose its water-resistivity. Maintenance and Inspection Periodically perform the following checks to ensure stable operation of the over a long period of time. Check for mounting position, dislocation, looseness or distortion of the and sensing objects. Check for loose wiring and connections, improper contacts and line breakage. Check for attachment or accumulation of metal powder or dust. Check for abnormal temperature conditions and other environmental conditions. Never disassemble or repair the. Environment Water Resistivity Do not use the underwater, outdoors or in the rain. Power Reset Time The is ready to operate within 00 ms after the is turned. If the load and are connected to independent power supplies respectively, be sure to turn the before supplying power to the load. Power The may output a pulse signal when it is turned. Therefore, it is recommended that the load be turned before turning the. Power Supply Transformer When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-transformer. Object The sensing of the vary with the Operating Environment Be sure to use the within its operating ambient temperature range and do not use the outdoors so that its reliability and life expectancy can be maintained. Although the is water resistive, a cover to protect the from water or water-soluble machining oil is recommended so that its reliability and life expectancy can be maintained. Do not use the in an environment with chemical gas (e.g., strong alkaline or acid gasses including nitric, chromic and concentrated sulfuric acid gases). Inrush Current A load that has a large inrush current (e.g., a lamp or motor) will damage the Snesor, in this case connect the load to the through a Relay 6 Inductive s
