Amplifier Built-in U-shaped Micro Photoelectric Sensor PM-45
Panasonic — PM-45 Series
A compact U-shaped (slot-type) micro photoelectric sensor with a built-in infrared LED emitter/receiver pair that detects objects by beam interruption across a fixed 6 mm gap. Used for pallet positioning, home-position detection on rotating bodies, and overrun detection on small moving mechanisms.
Key Features
- Fixed 6 mm sensing range, 0.01 mm repeatability
- IP64-rated, gap-free integrated molded body
- Reverse-polarity, reverse-output and short-circuit protection built in
- Six mounting variants with M2/M3 screw compatibility
- Multi-angle visible orange operation indicator
- NPN or PNP open-collector output
