Rugged magnetic speed sensor for high-speed industrial gear-tooth sensing.

18 mm Threaded Proximity Sensor

Item number PSA7B000

The PSA7B000 is a magnetic pickup sensor designed to detect moving ferrous targets, like gear teeth or sprockets. It generates an AC pulse signal without requiring external power, making it a reliable choice for tachometers and rate meters.


Features and benefits

  • Zero speed target detection

    Capable of sensing metal targets moving at extremely low speeds, all the way up to a 1 kHz switching frequency.

  • Visual LED status indicator

    Features a case-mounted LED that lights up when a target is sensed, simplifying alignment and troubleshooting.

  • Rugged NEMA 4X protection

    Epoxy encapsulated and impervious to dirt, oil, and moisture, making it ideal for washdown zones.

  • NPN open collector output

    Provides a sinking signal compatible with most Red Lion counters, rate meters, and PLC inputs.

  • Cylindrical M18 housing

    The standard 18mm threaded body allows for easy mounting through brackets or pre-tapped machine frames.

  • 5mm sensing distance

    Optimized for detecting gear teeth or shaft collars without requiring physical contact with moving parts.

  • Solid state reliability

    No moving internal parts mean a virtually unlimited mechanical life, even in high vibration environments.
