Right-Angle Liquid Water Level Float Switch (DC 220V) | Pro Tronix
Laser Module 650NM 5V
“A compact, high-efficiency 5V laser diode module emitting a bright red dot. Perfect for security systems, laser pointers, and optical experiments.”
LM393 Infrared Slot-Type Photoelectric Speed Sensor Module
“High-precision infrared correlation sensor for counting, speed measurement, and position detection. Featuring the LM393 comparator for a clean and stable digital signal.”
“The LM393 Photoelectric Sensor is an essential module for robotics and industrial automation. It uses a 5mm wide slot to house an infrared transmitter and receiver. When an object passes through the slot and breaks the light beam, the module output changes state. This makes it perfect for measuring motor speed (RPM) or counting objects on a conveyor belt.
