Description

The SS40A is a bipolar Hall-effect Sensor has thermally balanced integrated circuit over full temperature range. The bipolar magnetic respond to alternating North and South poles. A built-in regulator provides very stable operation over 4.5 to 24VDC supply voltage range and internal circuitry prevents sensor damage in case the supply voltage polarity is accidentally reversed. The bipolar hall-effect sensor is small, versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet. The open-collector sinking output voltage is easily interfaced with a wide variety of electronic circuits.
Miniature construction
Power consumption of only 5mA maximum at 4.5VDC for energy efficiency
Digital current sinking output
Bipolar magnetic for ring magnet applications
High output current capability (20mA)
High speed, operates from 0 to over 100kHz
Built-in reverse polarity protection
ESD sensitive device, take proper precaution while handling the device.
