Bipolar Hall-Effect Digital Position Sensor ICs: SS40F, SS40AF 005888 Issue 4 Datasheet FEATURES • Small, flat TO-92-style package size allows for a compact PC board layout • Current consumption of only 5 mA max at 4.5 Vdc for energy efficiency • Sensitive, bipolar magnetics respond to alternating North and South poles, making these products suited for speed sensing and RPM measurement • High speed: operates from 0 kHz to over 100 kHz • Built-in pull-up resistor can easily interface with common electronic circuits without adding external components, helping to reduce total system cost DESCRIPTION These small and versatile digital Hall-effect devices are operated by the magnetic field from a permanent magnet or an electromagnet, and are designed to respond to alternating North and South poles. The built-in regulator provides enhanced stability of operation from over a 4.5 Vdc to 24 Vdc supply voltage range, and internal circuitry is designed to prevent sensor damage in case the supply voltage polarity is accidentally reversed. The open-collector sinking output voltage is easily interfaced with a wide variety of electronic circuits. Both products are designed for high volume applications. The SS40F is factory tested at 25°C [77°F] and the SS40AF is factory tested at both 25°C [77°F] and 125°C [257°F]. These products are available in a flat TO-92-style package with straight leads in bulk packaging. • RoHS-compliant materials meet Directive 2002/95/EC POTENTIAL APPLICATIONS • Commercial: Door or lid closure detection in appliances, speed and RPM (revolutions per minute) sensing in fitness equipment, damper or valve position control in HVAC (heating, ventilation, and air conditioning) equipment, flowrate sensing in appliances and water softeners, printer head position sensing • Industrial: Flow rate sensing in industrial processes, robotic control (cylinder position monitoring), float-based fluid level sensing • Transportation: Brushless dc motor commutation, electronic window lift, anti-pinch power window systems, vehicle convertible roof position • Medical: Medical equipment using electric motors PORTFOLIO Other bipolar digital position sensor ICs include: • SS400 Series, SS500 Series (selected catalog listings) • SS311PT, SS411P • SS41, SS41-L, SS41-T2, SS41-T3, SS41-S, SS41-SP • SS51T • SS30AT, SS40A, SS50AT Sensing and Internet of Things Bipolar Hall-Effect Digital Position Sensor ICs: SS40F, SS40AF Table 1.

Honeywell recommends allowing 10 us after supply voltage has reached 4.5 V for the output voltage to stabilize. 2 Sensing and Internet of Things NOTICE The magnetic field strength (Gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic characteristics. To test the switch against the specified limits, the switch must be placed in a uniform magnetic field.
