Honeywell has expanded its Hall-effect sensor portfolio with the new SS311PT and 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 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.
SS311PT: Subminiature SOT-23 surface mount package size; supplied on tape and reel (3000 units per reel) SS411P: Small leaded, flat TO-92-style package; available in bulk package (1000 units per bag)
The new SS311PT and SS411P provide value for our customers by:
• Price competitive: Honeywell has downsized the integrated circuit, saving on
manufacturing costs while still meeting customer requirements; these savings result in lower costs for
customers
• Reduce total system cost: Built-in pull-up resistor eliminates the customer having to
purchase an external pull-up resistor for many applications, reducing total system cost
• Reduce power consumption: Low 2.7 Vdc voltage capability—the lowest in Honeywell’s digital
Hall-effect sensor portfolio—often helps reduce the sensor’s total power consumption
• Economical: SS311PT is supplied on tape and reel, often allowing for automated, lower-cost
pick and place assembly which can help the customer reduce manufacturing costs
• Subminiature size: SS311PT’s subminiature package size requires less printed circuit board
space, allowing for use in smaller assemblies
• Flexible: 2.7 Vdc to 7 Vdc supply voltage range allows for use in low voltage
applications
