High-precision Hall Effect sensor for zero-speed motion detection.

PSAH - Hall Effect Speed Sensor, NPN OC Output

Item number PSAH0000

The PSAH0000 features a 3/4" diameter stainless steel housing and operates on 8 to 30 VDC. It provides a clean NPN open collector output with a frequency range from 0 to 10 kHz. Epoxy encapsulated for durability, it is built to withstand harsh oil, dirt, and moisture-prone environments.


Features and benefits

  • True zero speed sensing

    Utilizes Hall Effect technology to detect targets regardless of how slowly they are moving, making it ideal for low speed monitoring and positioning.

  • High frequency range

    Capable of tracking pulses from 0 to 10 kHz, allowing it to accurately monitor everything from slow turning shafts to high speed industrial machinery.

  • Rugged stainless steel case

    The 3/4" (19 mm) diameter housing is made of 304 stainless steel, providing superior mechanical strength and protection against corrosion.

  • Epoxy encapsulated internals

    The entire sensor is sealed in epoxy, earning it a high level of resistance against oil, dirt, and moisture which is essential for factory floor reliability.

  • Wide operating voltage

    Works on a broad power range of 8 to 30 VDC, allowing it to be powered directly from most industrial counters, PLCs, or DC power supplies.

  • Small target sensitivity

    Engineered to detect targets as small as 24 DP (diametral pitch) gear teeth, giving it the precision needed for fine-toothed sensing applications.

  • Indeterminate output safety

    Features reverse polarity protection. Note that the output state is indeterminate (high or low) when first powered on if no metal is present at the sensor face.
