Honeywell SS400 Series Hall Effect Sensor, Bipolar Magnetic, 3.8V Minimum Supply Voltage - SS461A

This Hall effect sensor is a three‑pin digital magnetic switch designed for precise contactless position sensing in industrial electronics. It operates across a wide supply range and withstands elevated temperatures, making it suitable for robust control and detection tasks in automation and electrical systems without relying on mechanical contacts.

Features and Benefits:

• Bipolar magnetic switching enabling detection of north and south poles
  Digital output compatible with 3.8 V-30V supply rails
  Low quiescent current draw of 20 mA supporting efficient systems
  Wide operating temperature span from -40 °C to 150 °C for harsh environments
  Surface‑mount TO‑92 package for Compact board‑level integration
  Three‑pin Interface simplifying wiring and signal conditioning

Applications

• Suitable for brushless motor position sensing in drive assemblies
  Ideal for rotary and linear position feedback in automation
  Used for proximity detection in electrical control panels
  Can be used for non‑contact switching in mechanical safety interlocks

What mounting approach does it support for PCB implementation?

It is designed for surface mounting in a TO‑92‑style package that seats directly on the board with three leads for straightforward soldering.

How does the sensor behave with different magnetic orientations?

The bipolar configuration responds to both polarities, switching state when either north or south fields exceed its operate threshold.

What supply constraints should be observed in designs?

Ensure the supply is maintained within 3.8V to 30V to preserve correct digital switching and avoid overvoltage stress.

Does it tolerate elevated ambient operating conditions?

The device is specified to operate reliably across a range from -40 °C up to 150 °C for demanding temperature environments.

What electrical characteristic affects power budgeting?

The device draws a supply current of approximately 20 mA, which should be included in system power calculations.
