A Hall Effect gear tooth sensor detects 0-32 pitch gears, bolt heads, holes in steel plates, and other ferrous targets. Gear tooth sensors use a single-channel digital square wave output to resolve speed or count. Furthermore, the self-calibrating output reacts to both the leading and falling edge of any ferrous metal target.
So, how does a gear tooth sensor work? First, mount the sensor in any orientation and set the air gap within the range of the target using the supplied lock nuts. Then as the first gear tooth approaches, the PNP sensor will power up with the output transistor OFF (Vout Low). Then as each tooth approaches, the PNP sensors output transistor turns ON (Vout High). After the first tooth, the sensor will not miss a target. Conversely, when the NPN sensor is OFF the voltage output is High and Low when its ON.
Also, gear tooth product series are dynamic, self -adjusting and include no wearing parts, near zero speed detection, and internal hysteresis. Modify, enhance, or update all of our Hall Effect sensors with our modular features and functionality. Start by selecting a housing in aluminum, stainless-steel, plastic, threaded, flange mount, and customer specific. Need a different sensor functionality? Then choose some options like NPN, PNP, TTL, etc. Furthermore, customize your connectivity with Deutch, Amphenol and other brand connectors. Or select free-end wires and pigtails, including any length option.
