Relative collector current or coupling factor of the reflex sensors for reflection on various. Output from the voltage comparator is then processed by the output switch driver circuit wired around the far famed 8 pin timer chip lm555 ic2. Distance measuring sensor united with psd 2 infrared led and signal processing circuit short measuring cycle 16 5 ms compact lineup of various. Reflective optical sensor and optocoupler are two very different things.

6 346 2 71000 cut tape ct alternate packaging not for new designs 19 7 50cm 1 6 reflective non metallic surface mount 400ma. The current produced by the sensor is even smaller than the output currents of the. Reflective object proximity sensor. The vishay product from the first post is a reflective optical sensor not an optocoupler.

The reflective optical sensor os1 is directly attached to the input of the photoelectric sensor main circuit based on the popular 8 pin dual voltage comparator chip lm393 ic1. Output from the optoreflective sensor can be interfaced with a microcontroller or similar circuits. These optical sensors work in a similar way to the slotted opto sensor but rely on infra red light reflected from an object e g. It just reads the value from the sensor and displays it.

They are a non contact type of sensor often used in the automation industry. Connect pins k c a and e of the sensor module to pins 1 2 3 and 4 of con2 respectively. And yes it will work fine with an rpm disk if the disk sections alternately reflect and absorb the 950nm wavelength. The reflection of the various body surfaces in the infrared range can deviate significantly from that in the visible range.

Once you have the value you will need to determine if the beam is broken and what to do if it is. Sensor opt reflective 50cm 8wdfn 6 346 immediate available. A sheet of paper in a printer placed about 2mm to 8mm from the sensor to produce an output. Account for this fact when using reflex sensors.

Reflective optical sensors are photoelectrical sensors that are used to detect the presence or absence of objects or measure the distance to those objects. These days opto reflective sensor is used in various project like proximity sensing position detector robotics etc. They can be used to provide real time information in a manufacturing setting in order to keep processes running smoothly. Use a 4 wire cable for interconnection between the sensor and the pcb.

When a drop passes through the sensor the value goes low. I use the sensor to detect water drops. 5 for pin configuration of tcrt5000 sensor before using it in the circuit. The diy project posted here is of opto reflective sensor using 555 and tcrt5000 module.
