Microsonic Wu 102 Driver May 2026

The defining feature of the Wu 102 is its form factor. Unlike standard M18 or M30 cylindrical sensors, the Wu 102 utilizes a rectangular, wafer-thin housing.

The Wu 102 operates on the Time-of-Flight (ToF) principle: Microsonic Wu 102 Driver

Because the sensor uses sound rather than light (like photoelectric sensors), it is impervious to target color, transparency, or ambient light conditions. The defining feature of the Wu 102 is its form factor

Do not expect neutral performance straight out of the box. The Varilinear spider and rubber surround are incredibly stiff initially. You must burn in the Wu 102 for 50 hours minimum (100 hours recommended). Because the sensor uses sound rather than light

Assuming the MW102 is an ultrasonic driver for proximity sensing or cleaning, expected parameters include:
