Industrial MSP6735 Magnetic Speed Pickup Sensor

Industrial MSP6735 Magnetic Speed Pickup Sensor is a self-generating, AC-output speed sensor that detects rpm by sensing ferrous flywheel or ring gear teeth, delivering a frequency signal proportional to engine speed without external power. The sensor features a 3/4-16 UNF-2A threaded body for direct installation into flywheel housings and engine bell housings, with a thread length of about 3.0 in (76 mm) and an overall body length of about 3.45 in (88 mm). The sensor uses a Packard connector and outputs an AC frequency signal with typical 0.5 to 30 VAC RMS, with cranking output at least 1 VAC RMS. Electrical characteristics include a resistance range of 160 to 1200 ohms. Operating temperature range is from -65°F to +225°F (-55°C to +105°C) with an air gap setting of 0.025 to 0.035 in (0.64 to 0.89 mm). Power is self-generated, requiring no external power supply. Applications include diesel engines, generator sets, compressors, pumps, and industrial power equipment needing accurate RPM feedback for electronic speed control and overspeed protection, as well as governor feedback. Common replacements include MSP6724 and MSP6728.
