The PMDX-171 is a Hall effect sensor with fully conditioned NPN outputs.

• Hall Effect magnetic sensor detects a small magnet (supplied)
• Unipolar device, sensitive to North magnetic pole
• Typical activate 100 Gauss, typical release 50 Gauss
• Magnetic sensor leads stand 0.25" above PCB and can be bent to desired orientation
• Small size 1.575" by 0.600" circuit board is easy to mount using two screws
• Easy to use clamp style screw terminal strips for connections
• LED indicator for sensor output status
• Signals are conditioned by a Schmidt trigger to avoid multiple false transitions
• Both a True and a False output are provided so user can select desired polarity
• Outputs are NPN "open collector" style and provide either an open circuit or a path to ground depending on state of sensor
• Outputs work directly with PMDX breakout board inputs and any other board that provide a "pull-up"
• Sensor may be powered by any DC voltage from 5 volts to 25 volts
• Output voltage is independent of supply voltage
• Response time of less than 5 uS
• Mounting area of circuit board is free of electrically conducting PCB traces
• SMT component side is conformal coated to help resist harsh environments
• NOT recommended where ferrous metal chips may stick to magnet
