Everlight PT334-6B Alternative: Why Beephoton PTCP001-202 is the Smarter Pick for Optical Switches
If you’ve been dealing with the Everlight PT334-6B in your designs, you probably know it pretty well by now. It’s that solid 5mm phototransistor that’s
How to Protect Phototransistors from Electrostatic Discharge (ESD)
If you’ve ever messed around with phototransistors in a project, you know they can stop working outta nowhere. Turns out, a lot of times its
Custom Phototransistor: Tailoring Window Materials and Pin Configurations for Your Needs
If you’ve ever messed around with off-the-shelf phototransistors and thought, “this almost works, but if only the window filtered out more visible light” or “why
Infrared Remote Control Systems: Designing with 940nm Phototransistors
If you’ve ever wondered what makes those TV remotes work so reliably, it’s all about infrared light bouncing around invisibly. Most folks don’t think much
Building Safety Light Curtains: The Role of Reliable Phototransistors
If you’ve ever worked around big machines in a factory, you know how quickly things can go wrong if someone’s hand gets too close to
How to Design an Optical Switch Using Si PIN Phototransistors
Optical switches are pretty cool little setups that let you detect stuff without any physical contact. I’ve messed around with these a ton over the
