SS41 High-performance Unipolar Hall Effect Sensor Manufactured For Position Sensing Proximity Detection
Key Features:
- Unipolar magnetic operation (triggers with south pole of magnet, resets with removal).
- Wide operating voltage range for flexible system integration.
- High-temperature tolerance suitable for harsh industrial environments.
- Fast response time enables high-speed sensing applications.
- Compact, industry-standard TO-92 package for easy mounting and replacement.
- Built-in reverse voltage protection and ESD resistance for enhanced durability.
- Low power consumption for battery-powered or energy-efficient devices.
Applications:
- Position sensing (e.g., limit switches, door/window position detectors, gear tooth counting).
- Proximity detection (e.g., object presence/absence in industrial automation, consumer electronics).
- Speed sensing (e.g., motor RPM measurement, fan speed monitoring, wheel speed detection).
- Automotive systems (e.g., ignition timing, transmission position sensing, seatbelt latch detection).
- Industrial automation (e.g., conveyor belt position control, valve position feedback).
- Consumer electronics (e.g., laptop lid open/close detection, appliance door interlocks).
- Robotics (e.g., joint position sensing, end-effector proximity detection).
