They are a non contact type of sensor often used in the automation industry. I use the sensor to detect water drops. Connect pins k c a and e of the sensor module to pins 1 2 3 and 4 of con2 respectively. Use a 4 wire cable for interconnection between the sensor and the pcb.

These days opto reflective sensor is used in various project like proximity sensing position detector robotics etc. Thus we had posted a diy project with working range of 2mm to 10mm. 5 for pin configuration of tcrt5000 sensor before using it in the circuit. Sensor opt reflective 50cm 8wdfn 6 346 immediate available.

Reflective object proximity sensor. Account for this fact when using reflex sensors. The diy project posted here is of opto reflective sensor using 555 and tcrt5000 module. Relative collector current or coupling factor of the reflex sensors for reflection on various.

Once you have the value you will need to determine if the beam is broken and what to do if it is. Distance measuring lineup pdf 393kb back next.

A sheet of paper in a printer placed about 2mm to 8mm from the sensor to produce an output.

The reflection of the various body surfaces in the infrared range can deviate significantly from that in the visible range. They can be used to provide real time information in a manufacturing setting in order to keep processes running smoothly. 6 346 2 71000 cut tape ct alternate packaging not for new designs 19 7 50cm 1 6 reflective non metallic surface mount 400ma. And yes it will work fine with an rpm disk if the disk sections alternately reflect and absorb the 950nm wavelength.

Output from the optoreflective sensor can be interfaced with a microcontroller or similar circuits. Reflective optical sensor and optocoupler are two very different things. 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. When a drop passes through the sensor the value goes low.

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. Reflective optical sensors are photoelectrical sensors that are used to detect the presence or absence of objects or measure the distance to those objects. The current produced by the sensor is even smaller than the output currents of the. The vishay product from the first post is a reflective optical sensor not an optocoupler.
