And yes it will work fine with an rpm disk if the disk sections alternately reflect and absorb the 950nm wavelength.
These days opto reflective sensor is used in various project like proximity sensing position detector robotics etc.
Distance measuring sensors distance measuring sensor lineup new product.

They are a non contact type of sensor often used in the automation industry.
When a drop passes through the sensor the value goes low.
Reflective object proximity sensor.
They can be used to provide real time information in a manufacturing setting in order to keep processes running smoothly.
Thus we had posted a diy project with working range of 2mm to 10mm.
I use the sensor to detect water drops.
The diy project posted here is of opto reflective sensor using 555 and tcrt5000 module.
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.
The above code is very simple.
The current produced by the sensor is even smaller than the output currents of the.
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 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.
Connect pins k c a and e of the sensor module to pins 1 2 3 and 4 of con2 respectively.
5 for pin configuration of tcrt5000 sensor before using it in the circuit.
Use a 4 wire cable for interconnection between the sensor and the pcb.

Once you have the value you will need to determine if the beam is broken and what to do if it is.
Distance measuring sensor united with psd 2 infrared led and signal processing circuit short measuring cycle 16 5 ms compact lineup of various.
Relative collector current or coupling factor of the reflex sensors for reflection on various.
Reflective optical sensor and optocoupler are two very different things.
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.
The vishay product from the first post is a reflective optical sensor not an optocoupler.
The reflection of the various body surfaces in the infrared range can deviate significantly from that in the visible range.
