photomicrosensors technical guide installation ? the photomicrosensors with non-modulated light (models that begin with ee-sx or ee-sy) are built into the device being used and are, therefore, not equipped to deal with interference from an external light source. when using a photomicrosensor with non- modulated light in an area exposed to an incandescent light or other external light interference, install so as to minimize the effects of external light sources. ? mount the photomicrosensors securely on a flat surface ? mount the photomicrosensors with m3 screws, using a spring washer to ensure the screws will not become loose. use a tightening force of 0.59 nm max. note: be sure to read the precautions for the model being used before tightening the screws. ? install so that nothing can collide with the sensing section of the photomicrosensor. damage to the sensing surface will cause inferior performance. ? before using the photomicrosensor, check to be sure that it has not become loose due to vibration or shock. wiring surge ? if there is surge in the power supply line, try connecting a capacitor (with a capacitance of 0.1 to 1 f) or a zener diode (z d in the diagram below, with a rated voltage of 30 to 35 v). use the sensor only after confirming that the surge has been removed. ? when driving a small inductive load, such as a relay, wire as shown below. (be sure to connect a diode to absorb the reverse voltage.) ? separate the wiring for the photomicrosensor from high-voltage lines or power lines. if the wiring is routed in the same conduit or duct as such lines, the photomicrosensor may malfunction or may be damaged by inductive interference. ? make sure that the connectors (either dedicated or commercially available) are securely locked. voltage output ? a sensor with an open-collector output can be connected to a counter with a voltage input by connecting a resistor between the power source and output. select a resistor with reference to the following example. the resistance of the resistor is generally 4.7 k and its wattage is 1/2 w for a supply voltage of 24 v and 1/4 w for 12 v. if resistance r = 4.7 k for the ee-sx670, the input voltage at the high level is as follows: and the input voltage and load current at the low level are as follows: input voltage v l 0.4 v (residual voltage for 40-ma load current) note: refer to the ratings of the sensor for the residual voltage of the load current. handling methods when wiring ? do not apply stress (external force) to the terminals as shown in the figure below. stress may damage the terminals. precautions for correct use z d z d : zener diode l out 0.1 to 1 f out + v 0 v d relay x sw main circuit tr +vcc ee-sx670 counter (voltage input) insert a resistor output 0v 0v r 24 v power supply z input terminal (cp) input impedance: approx. 4.7 k input voltage v h = z r+z vcc = 4.7k 4.7k + 4.7k 24v =12v load current ic = vcc r = = 5.1ma 40ma vcc r terminal terminal http://www.ia.omron.com/ c-2 (c)copyright omron corporation 2008 all rights reserved.
photomicrosensors technical guide design considerations precautions for photomicrosensors wi th modulated light when using photomicrosensors with modulated light (models that begin with ee-sp), the design must take into account the effects of power source and cable length. photomicrosensors with modulated light are more easily affected than photomicrosensors with non- modulated light (models that begin with ee-sx or ee-sy). photomicrosensors with modulated light that are easily affected: ee-spx301/401, ee-spy30 @ /40@ , e-spz301@ /401 @ , ee-spy31 @ /41@ , ee-spx303/403, ee-spw311/411, ee-spx74 @ /84@ , ee-spx @@@ -w photomicrosensors with modulated light that are not easily affected: ee-spx613, ee-spy801/802 reasons for interference from power and cable length on photomicrosensors with modulated light as explained in principles, an led emitter is pulse-lighted to produce modulated light. a large current momentarily flows to the photomicrosensor in sync with this pulse timing. this causes a pulsating consumption current. a photoelectric sensor incorporates a capacitor with sufficient capacity, and is virtually unaffected by the pulse of the consumption current. with a small photomicrosensor, however, it is difficult to have a capacitor with a sufficient capacity. accordingly, when the cable length is long or depending on the type of power source, it may become impossible to keep up with the pulse of the consumption current and operation may become unstable. countermeasures attach a capacitor of 10 f min. (e.g., a film capacitor) to the wires as close as possible to the sensor. (use a capacitor with a dielectric strength that is at least twice the sensor ' s power supply voltage. do not use tantalum capacitors. a short-circuit may cause the capacitor to ignite due to the large current flow.) design the configuration so that the maximum total cable length for the photomicrosensor with modulated light is 2 m. ? when using a cable longer than 2 m, attach a capacitor (e.g., an aluminum electrolytic capacitor) with a capacity of approximately 10 f to the wires as shown below. the distance between the terminal and the capacitor must be within 2 m. make sure that the total cable length is no longer than 5 m. to use a cable length longer than 5 m, use a plc or other means to read the sensor output and then transmit the signals using a plc ' s communications. ? regardless of whether a photomicrosensor with modulated light or a photomicrosensor with non-modulated light is used, make sure that the total combined length of the photomicrosensor cable and the connecting cable is less than 10 m. ? although cables are capable of being extended longer than 5 m, performance is likely to be affected by noise interference from adjacent cables and other devices. voltage drops due to the resistance of the cable material itself will also influence performance. therefore, factors, such as the difference in voltage between the end of the cable and the sensor and noise levels, must be given full consideration. emitter (lb) main circuit 5 to 24 vdc 10 f or higher current vcc out gnd 2 m max. capacitance of 10 f min. 12 to 24 vdc 0 v extension cable out http://www.ia.omron.com/ c-3 (c)copyright omron corporation 2008 all rights reserved.
photomicrosensors technical guide ? take either of the following countermeasures as required if connecting a photomicrosensor with modulated light to a switching power supply. (1) attach a capacitor of 10 f min. to the wires as close as possible to the photomicrosensor. (use a capacitor with a dielectric strength that is at least twice the photomicrosensor 's power supply voltage. do not use tantalum capacitors. a short-circuit may cause the capacitor to ignite due to the large current flow.) (2) connect to the 0-v line of the power source or connect to the power source via a capacitor of approximately 0.47 f to reduce the impedance of the mounting base to prevent inductive noise from entering the mounting base. (3) connect the noise filter terminal (neutral terminal to acg) of the switching power supply to the case (fg) and 0-v terminal of the power supply. (4) insert a plastic insulator of approximately 10 mm between the sensor and the mounting base. ? when there is inductive noise in the sensor mounting frame (metal), the output of the sensor may be affected. in this case, ensure that there is no electrical potential difference between the sensor 0-v terminal and the sensor mounting frame, or put a 0.47- f capacitor between the 0-v terminal and the frame. precautions for reflective photomicrosensors ? the reflective photomicrosensor model is based on sensing a sheet of white paper with a reflection factor of 90%. the sensing distance varies with the other conditions of the objects being detected. ee-spy30/40 series ? use the sensor only after carefully studying the possibility of light entering the sensor due to light being reflected off background objects. decrease reflection from the background object, e.g., by providing a sufficient distance to the background or by using a black sponge as the background. the line connected as mentioned above should be grounded or connected to the mounting base to ensure stable operation .
