The Honeywell T4C Hall-effect sensor generates square wave signals proportional to rotary speeds and also provides directional indication. The T4C consists of two back-biased Hall-effect ICs that are zero-speed capable. The sensor must be oriented to the target using a special orientation sleeve. Zero-speed capabilities allow the T4C to also be used as a proximity switch.
