FG Wilson 171232 Magnetic Pickup Sensor

The 171-232 magnetic pickup sensor is a variable reluctance speed sensor designed for engine speed monitoring on FG Wilson generator sets powered by Perkins 1306 series diesel engines. It generates an AC sine wave signal proportional to engine RPM for the engine control module or governor system. Constructed with a stainless steel threaded body and sealed epoxy encapsulation for resistance to vibration, oil, and high temperature environments. The sensor features a 50 mm thread length with M16 x 1.5 or 5/8-18 UNF thread pitch options depending on specific engine build configuration.
