Honeywell 91SS12-2, Doğrusal Hall Etkili Sensör, 3-Pinli SIP

Honeywell 91SS12 Series Hall Effect Sensor, 3.75mV/g Sensitivity, 19mA Supply Current - 91SS12-2

This hall-effect sensor is a three-pin analogue magnetic sensor designed for inline detection of magnetic fields in electronic and electromechanical systems. It operates from a low-voltage supply and provides a linear magnetic output suited to signal conditioning in control and measurement circuits. The component is supplied in a single in-line package for through-hole mounting and is RoHS compliant.

Features and Benefits:

• 3.75mV/g sensitivity for precise magnetic-to-voltage conversion
  19mA supply current ensuring predictable power draw for designs
  Operates from -0.5V to 18V enabling flexible supply choices
  -40°C to 150°C operating range for extreme temperature environments
  Linear magnetic response for straightforward signal processing
  Three-pin SIP through-hole format for simple PCB assembly

Applications

• Suitable for motor commutation feedback in industrial drives
  Ideal for position sensing in factory automation equipment
  Used for magnetic proximity detection in safety interlocks
  Can be used for vibration-related magnetic monitoring systems
  Used with analogue signal chains in instrumentation panels

What electrical input limits should be observed to prevent damage?

Do not exceed the maximum supply voltage of 18V and avoid negative supply excursions beyond -0.5V to protect the internal circuitry.

How does the sensor behave under varying temperature conditions?

It is specified to operate over a wide temperature span from -40°C to 150°C, maintaining linear magnetic output across that range.

What mechanical mounting considerations apply for PCB integration?

The single in-line package is intended for through-hole mounting with three pins, permitting secure soldered attachment to printed circuit boards.

What current budget should designers allocate per device?

Allocate approximately 19mA of supply current per sensor when planning power distribution and thermal considerations.
