PM-T45
Overview
The PM-T45 is a U-shaped through-beam photoelectric sensor from Panasonic designed for precise position sensing in industrial automation. It features a built-in amplifier and a 6mm sensing gap, supporting a wide supply voltage range from 5V to 24V DC. The sensor provides dual NPN open-collector outputs for both Light-ON and Dark-ON logic states.
Why Choose This Part
The sensor offers high-speed response times of 20us or less for Light-ON transitions, enabling high-frequency switching. Its integrated design includes two independent outputs (Light-ON/Dark-ON), simplifying wiring and logic design without requiring external inverters. The chassis-mount U-shaped housing is compact at 26mm in length and features a durable cable connection for reliable operation in industrial environments.
Applications
Key Specifications
Getting Started
To integrate the PM-T45, connect the brown lead to 5-24V DC and the blue lead to 0V. The black and white wires provide NPN open-collector outputs which require external pull-up resistors if the micro-controller or PLC does not have internal pull-ups. Ensure the 6mm slot is clear of debris and that the load current does not exceed 50mA to prevent damage to the output transistors.
