ee-spx74/84 ee-spx74/84 5 precautions installation connections do not connect the ee-spx to an ac (100 vac) power supply. doing so may cause ignition, burning, or other damage. sensor load brown black blue do not use the ee-spx at voltages exceeding the rated voltage range. doing so may cause the ee-spx to be damaged or burned. wire the ee-spx correctly with the correct polarity. failure to do so may cause the ee-spx to be damaged or burned. sensor load brown black blue do not short-circuit the load (i.e., do not connect a power supply directly to the sensor) as shown below. doing so may cause the ee-spx to be damaged or burned. sensor load brown black blue load short-circuiting correct design setup cable extensions use a cable with a minimum wiring cross-section surface area of 0.15 mm 2 and no greater than 4 m in length. if the wiring exceeds 4 m, connect a 10 f capacitor within the 4 m mark, as shown in the diagram. (use a condenser with a withstand pressure of at least twice the sensor power source voltage.) 5 to 24 vdc capacitor 10 f min. 4 m max. extension cable 0 v power source when using a switching regulator on general sale, take the following countermeasures. 1. connect a 0 v line to the power source near the sensor to reduce impedance from the mounting, so as to prevent in- duction noise in the vicinity of the sensor. also, connect the line via a capacitor (up to 0.47 f). mounting base sensor switching power source (0.47 f) 0 v 2. connect a noise filter terminal (middle point terminal to acg) for the switching power source to the body of equipment (fg) for the power source and the 0 v. a more stable operation can be obtained by connecting the already-connected line to ground or to the mounting (as recommended by all power source manufacturers). sensor mounting base to power source to sensor switching power source input ground 0 v 3. insert a plastic insulator about 10 mm thick between the sen- sor and the mounting. effects of induced noise if there is induced noise in the (metal) mounting of the sensor, it may cause an effect similar to light on in the sensor. in such a case, connect the photomicrosensor 0 v terminal and the (metal) mounting at the same electric potential. also, connect the 0 v terminal and the metal mounting via a 0.47 f capacitor. sensor mounting base power source 5 to 24 vdc 0 v 0.47 f 0 v
ee-spx74/84 ee-spx74/84 mounting be sure to mount the sensor securely to flat plates. the characteristics of the through-beam sensor change if the slot is deformed. use m3.0 screws when mounting the ee-spx. be sure to use spring washers with the screws so that the screws will not loosen. the tightening torque applied to each screw must be no more than 0.59 n m (6 kgf cm). make sure that nothing will come into contact with the sensing element of the sensor. if the sensing element has scratch damage, the characteristics of the sensor will decrease. make sure that the ee-spx is securely mounted and not loosened by vibration or shock. wiring countermeasures against surge if the power supply has surge voltage, connect a zener diode withstanding 30 to 35 v or 0.1 to 1- f capacitor in parallel to the power supply to absorb the surge voltage. z d : zener diode 0.1 to 1 f if the load is a relay or other small inductive load, connect the load to the ee-spx as shown below. be sure to connect a diode for counter-voltage absorption. relay +v 0 v do not wire power lines or high-tension lines alongside the lines of the ee-spx in the same conduit, otherwise the ee-spx may be damaged or malfunction due to induction. be sure to wire the lines of the ee-spx separately from power lines or high-tension lines or lay them in an exclusive, shielded conduit. environment do not wire the ee-spx while power is applied, or the ee-spx may be damaged. to avoid damage or malfunction, do not install the ee-spx in the following locations: ? locations with excessive dust ? locations with corrosive gas ? locations where water, oil, or chemical is directly sprayed ? outdoors or locations exposed to direct sunlight make sure that the ambient operating temperature is within the rated range. the sensor may be soluble in organic solvent, acid, and alkaline, aromatic hydrocarbon, and chlorinated aliphatic hydrocarbon solvents. the characteristics of the sensor may decrease as a result, so make sure that the sensor is free from these solutions. cat. no. e309 ? e3 ? 1 7/00/2.5m specifications subject to change without notice. printed in u.s.a. omron electronics, inc. one east commerce drive schaumburg, il 60173 note: dimensions shown are in millimeters. to convert millimeters to inches divide by 25.4. 1-800-55-omron omron canada, inc. 885 milner avenue scarborough, ontario m1b 5v8 416-286-6465
