Sensing Gears are available in a variety of sizes to cover most applications where a sensor is to be used, but a suitable existing machine gear is not available. Split‑type gears are convenient for use on machine drive shafts where a shaft‑end is not available to mount a standard gear. Hubless gears are ideal for mounting in tight locations or when only a short shaft stub is available. Hubtype, Split, and Hubless gears can be supplied with special bores.
