SS40AF-1

Product 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.

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

• 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, flow rate 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
