Honeywell SNDH-H Series Hall-Effect Speed Sensors use a Hall-effect IC and a permanent magnet to detect ferrous metal targets, providing a digital pulse output proportional to target speed. These sensors operate reliably in dusty or dirty conditions with an air gap tolerance of up to 2.5mm and support high frequencies up to 15kHz for fast rotations. The SNDH-H sensors are available in multiple housing materials, lengths, and connector options to suit various applications, with some models functioning in temperatures from -40°C to 150°C. Omnidirectional design of these sensors simplifies installation, while zero-speed variants detect when rotation has completely stopped.
