has expanded its Hall-effect sensor portfolio with the new
SS411P Bipolar Hall-Effect Digital Position Sensors with Pull-Up Resistor
. These devices differ from Honeywell's existing digital Hall-effect sensors in that the SS311PT and SS411P have a built-in pull-up resistor and a low 2.7 Vdc voltage capability—the lowest rating in Honeywell's digital portfolio. Additionally, these products join the recently introduced SS30AT, SS361RT, SS461R, SS340RT, and SS440R Series digital Hall-effect sensors that consist of a downsized integrated circuit, resulting in lower costs for customers.
These cost-effective Honeywell bipolar sensors are designed to operate in simple, high-volume, cost-sensitive, rotary sensing applications. They are small, versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet, designed to respond to alternating North and South poles.
These bipolar sensors have enhanced sensitivity which allows for the use of smaller, often less expensive magnets. The internal pull-up resistor often eliminates the need for external components, further helping to reduce system cost. These economical bipolar sensors are suited for many simple, high volume, cost-sensitive, rotary sensing applications.
The 2.7 Vdc to 7 Vdc supply voltage range allows this device to be used in low voltage applications. The S311PT's very small size requires less PCB (printed circuit board) space, allowing it to be used in smaller assemblies.
These sensors are available in two package styles: the SS311PT in the subminiature SOT-23 surface mount package and the SS411P in the leaded, flat TO-92-style package.
