Description

The SL353LT from Honeywell is a solid-state Hall effect sensor that utilizes semiconductor technology to detect the presence and strength of a magnetic field. Its omnipolar design simplifies system integration, as it responds to either magnetic polarity without requiring specific orientation. The sensor outputs a clean digital signal, making it directly compatible with microcontrollers and logic circuits.

Housed in a robust SOT-23-3 surface-mount package, it is designed for automated assembly processes and offers reliable performance across a broad industrial temperature range. This sensor is a fundamental component for implementing non-contact switching, position feedback, and speed sensing in demanding environments.

Key Features

  • Omnipolar magnetic field detection for simplified design and mounting.
  • Low-power operation with a typical 9 mA supply current at 5V.
  • Industrial-grade temperature tolerance from -40°C to +85°C.
  • Surface-mount SOT-23-3 package enables high-density PCB layouts.
  • Digital output capable of driving LEDs or interfacing directly with MCU GPIO.
  • High-reliability construction from a leading industrial sensor manufacturer.

Applications

  • Lid/door closure detection in laptops, appliances, and consumer devices.

Frequently Asked Questions

What does 'omnipolar' mean for this Hall effect sensor?

Omnipolar means the SL353LT is activated by either the North or South pole of a magnet. This simplifies design as sensor orientation relative to the magnet's polarity is not critical, making it versatile for applications like lid switches or non-directional proximity detection.

What is the operating voltage and current requirement for the SL353LT?

The sensor operates at a nominal 5V DC supply. Under typical conditions, it draws a supply current of approximately 9 mA. Its digital output can sink or source up to 5 mA, which is sufficient to drive an LED or interface directly with a microcontroller's input pin.

How do I interface the SL353LT sensor with an Arduino or other microcontroller?

Connect VCC to 5V, GND to ground, and the output pin to a digital input pin on your microcontroller. The output is digital (high/low). Use a pull-up resistor (typically 10kΩ) on the output pin to VCC if the MCU's internal pull-up is insufficient for reliable reading of the open-drain output.

What is the typical magnetic field strength required to activate the sensor?

The sensor's operating point (Bop) is specified between 20 Gauss (G) and 110 Gauss. A magnet providing a field strength within this range at the sensor's face will trigger the output. The release point (Brp) is typically lower, providing hysteresis for stable switching.
