PM-L45
Overview
The PM-L45 is a U-shaped through-beam photoelectric sensor designed for precise position sensing and industrial automation. It features a wide 5V to 24V supply range and a built-in amplifier, allowing it to interface directly with PLC inputs or microcontrollers. The sensor provides an NPN open-collector output with a fast response time of 20 microseconds or less in certain conditions, making it suitable for high-speed detection tasks.
Why Choose This Part
The sensor features a compact chassis-mount design with pre-wired leads, reducing assembly time compared to connector-based models. Its wide operating voltage and 50mA output capacity allow it to drive small relays or logic circuits directly without additional buffering.
Applications
Key Specifications
Getting Started
Connect the brown wire to supply voltage (5-24V DC) and the blue wire to ground. The black wire provides the NPN open-collector output; use a pull-up resistor if connecting to a high-impedance digital input on a microcontroller like an Arduino or ESP32.
