Honeywell SS400 Series Hall Effect Sensor, 28V Maximum Supply Voltage, -40°C Minimum Operating Temperature - SS451A

This hall-effect sensor converts magnetic-field presence into a digital switching signal for use in electronic control and sensing systems. Designed for surface mounting, it operates as an omnipolar magnetic switch that responds to either magnetic polarity and is suited to industrial automation and electronic measurement contexts where a compact, solid-state proximity sensor is required.

Features and Benefits:

• Digital output with 20 mA supply current enabling low-power signalling • Operates from ±28V supply allowing wide voltage compatibility • Temperature tolerance from -40°C to 150°C supporting harsh environments • Omnipolar sensitivity permitting detection of either magnetic polarity • Three-pin surface-mount format facilitating straightforward PCB integration

Applications

• Suitable for magnetic position sensing in actuators and valves • Ideal for contactless speed or rotation detection systems • Used with control electronics in factory automation equipment • Can be used for proximity detection in electrical enclosures

How does it behave when exposed to different magnetic polarities?

It switches its digital output regardless of north or south pole orientation because the sensor responds to magnetic flux of either polarity.

What mounting considerations are required for reliable performance?

It is intended for surface-mount use and should be soldered into a suitable three-pin footprint with appropriate thermal management for high-temperature operation.

How should the supply be applied to avoid damage?

The device accepts supply voltages up to 28V and can tolerate negative supply down to -28 V

ensure system wiring prevents excursions beyond these limits.

Are there environmental restrictions for long-term operation?

It remains operational across a broad temperature span from -40°C to 150°C, so ambient and local heat sources should be assessed to remain within these bounds.
