- Photo-transistor output gives clean digital switching
- 9 mm slot width fits standard PCB layouts
- 8 mm detection distance for reliable object sensing
- Operating range from -55 °C to 100 °C suits harsh environments
- Pack of 10 sensors supports volume assembly needs
Slot Photo Interrupter Pack
This pack contains ten HY860H slotted optical sensors with a 5/16 inch gap and photo-transistor output. They suit engineers, hobbyists and repair technicians who need reliable object detection or position sensing in printers, scanners, vending machines or custom automation projects. Each unit operates on an infrared beam interrupted by opaque objects passing through the slot.
Simple Through-Hole Mounting
The sensors have four pins on 0.36 inch leads for standard PCB through-hole soldering with a total body length of 0.97 inch. Polarity matters: the IR diode accepts up to 50 milliampere forward current and 5 volt reverse voltage, while the photo-transistor handles 30 volt collector-emitter and 5 volt emitter-collector limits. Exceeding the 75 milliwatt transistor or 100 milliwatt diode dissipation ratings during soldering or operation is the most common cause of early failure.
Verify Voltage And Slot Fit
Before ordering, confirm your circuit can supply the IR diode within its 50 milliampere forward current and 5 volt reverse limits and that your logic level matches the transistor’s 20 milliampere collector current rating. Check that the 7.9 millimetre slot width and 9.66 millimetre depth accommodate the opaque flag or media you intend to detect, because the 8 millimetre detection distance is fixed and cannot be adjusted. Ensure the operating environment stays within the minus 55 to 100 Celsius range.

Questions about this item
How can I verify the HY860H sensor is working after soldering it to the PCB?
Apply forward current to the IR diode up to 50mA, insert an opaque object into the 7.9mm slot, and measure the photo transistor switching from ON to OFF state with collector current up to 20mA.
What exactly is included in the package and do I need any extra components?
The package contains 10 pieces of the HY860H optical sensor switch only; current-limiting resistors for the IR diode and pull-up resistors for the photo transistor output must be sourced separately.
Which slot width version should I choose for my application?
This model has a fixed 5/16 inch (7.9mm) slot width and 8mm detection distance; choose it when your opaque detection object fits those dimensions and the 9.66mm slot depth suits your PCB layout.
