A flange mount Hall effect sensor with integral LED for visual indication of operation, 34.00mm (1.339") x 14.00mm (0.551") x 10.00mm (0.394") with a choice of digital or latching outputs. Available in 3-wire (voltage output) version. Its case design enables screw or adhesive mounting. Capable of switching up to 28Vdc and 20mA. Available with a range of sensitivity, cable length and connector options. Ideally suited for position and limit sensing, rotation and flow measurement, commutation of brushless DC motors, angular sensing and magnetic encoding. Functions best with the H-58 magnet.

Note: The H-58 magnet is sold separately.
