Dual Hall Effect switch sensors produce dual pulsing outputs. 1 south pole and 1 north pole output. So, these non contact magnetic sensors function as a directional limit switch. First, mount the actuator magnets at each end of the range of motion. Next, set the air gap within range of the target magnets using the supplied lock nuts. Note that the sensor does not require orientation. Finally, when the south pole element is near the sensor face, channel A output is low and switched on. While channel B output is high and switched off. Notice that the south pole element will detect a slightly greater operating gap, given its closer proximity to the sensor face. Also, the target magnets' size, material, grade, and temperature determine the operating and release gap.
Dual Hall Effect switch sensors offer a greater detection gap than our standard DHS series. Other features include no wearing parts, true zero speed detection, and rugged sealed housing. All our Hall Effect sensors can be modified, enhanced, or updated with our modular features and functionality. Choose from various housings in aluminum, stainless-steel, plastic, threaded, flange mount, and customer specific. Available sensor functionality includes NPN, PNP, TTL, etc. Connectivity options such as Deutch, Amphenol and many others, free-end wires pigtails, any length.
