SS460P Honeywell Hall Effect Sensor

Description

The SS460P  Honeywell Hall Effect Sensor , SS360PT/SS460P High Sensitivity Latching Hall-Effect Sensor ICs with Built-in Pull-up Resistor are small, sensitive, and versatile devices that are operated by the magnetic field from a permanent magnet or an electromagnet. SS460P Hall Effect Sensors are designed to respond to alternating North and South poles. The SS360PT is activated by a North pole while the SS460P is activated by a South pole. The SS360PT/SS460P offers reliable switching points with a high magnetic sensitivity of 30 G typically (55 G maximum).

This sensor IC does not use chopper stabilization on the Hall element, providing a clean output signal and a faster latch response time when compared to competitive high-sensitivity Hall-effect bipolar latching sensor ICs which do use chopper stabilization. The internal pull-up resistor often eliminates the need for external components, helping to reduce the system’s cost. This high-performance yet economical sensor ICs are well-suited for demanding, cost-sensitive high-volume applications.

These products offer reverse polarity protection, deliver a stable output over a -40 °C to 125 °C [-40 °F to 257 °F] temperature range, and can accept a dc supply voltage from 3 Vdc up to 24 Vdc (see specifications below for details). For brushless dc motor manufacturers that need latching sensors with reliable, consistent performance for more efficient and smaller designs, Honeywell’s new family of High Sensitivity HallEffect Latching Sensor ICs with Built-in Pull-up resistors responds to low magnetic fields and offers repeatable operation while delivering faster response times to a change in magnetic field for better motor efficiency.

FEATURES AND BENEFITS
• Fastest response time in its class: Provides more efficiency in commutating a brushless dc motor
• No chopper stabilization: Results in a clean output signal
• High sensitivity: Operates from only 30 Gauss typical, at 25 °C [77 °F] and 55 Gauss maximum over the full -40 °C to 125 °C [-40 °F to 257 °F] temperature range, allowing for the  use of smaller, magnets or a wider air gap
• Internal pull-up Hall IC design: Simplifies installation and helps reduce component count and system cost
• Bipolar latching magnetics: Makes these products wellsuited for accurate speed sensing and RPM (revolutions per minute) measurement
• Sub-miniature, SOT-23 surface mount package (SS360PT) supplied on tape and reel: Allows for a compact design with automated component placement
• Small, leaded, flat TO-92-style package (SS460P): Allows for a compact PC board layout
• Wide operating voltage range of 3 Vdc to 24 Vdc: Allows for potential use in a wide range of applications
• Built-in reverse voltage capability: Enhances the protection of the sensor and the circuits
• Robust design: Allows operation up to 125 °C [257 °F]
• RoHS-compliant material meets directive 2002/95
