FSI Technologies Inc. manufactures a full line of high performance rotary encoders, photo-electric sensors, and controls for use in industrial, commercial and medical applications. We were founded in 1959 as FSI / Fork Standards and are committed to innovation, quality and performance.
FSI has been designing and manufacturing high quality optical incremental rotary shaft encoders for industrial, commercial and medical applications for over 50 years.
FSI encoders are widely recognized for their legendary quality and durability. In addition to our "Fork Standards" cube encoders, FSI has partnered with Kwangwoo to provide a complete line of competitively-priced, high-quality, industrial-grade optical encoders, both solid and hollow shaft.
FSI has pioneered many types of photoelectric sensor designs, available as diffused photoelectric sensors, retro-reflective photoelectric sensors & modulated high-speed retro-reflective photoelectric sensors.
FSI also offers a full line of electronic counters and controllers which are fully compatible with encoder, sensor and contact closure inputs, including counter-based controllers, single/dual output rate controllers, position controllers, cut-to-length controllers & dual output rate/count controllers.
FSI offers a complete line of encoder accessories including measuring wheels, cables, mounting brackets and couplings.
