Overview

SS461C Hall-effect digital position sensor IC, high sensitivity, latching, flat TO-92-style package, straight standard leads, 1000 units/bag.

The SS361CT/SS461C latches are small, sensitive and versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating North and South poles.

These bipolar sensor ICs have enhanced sensitivity which often allows for the use of less expensive magnets.

They offer reverse polarity protection and deliver a stable output over a -40 °C to 125 °C [-40 °F to 257 °F] temperature range. Operation from any dc supply voltage from 4 Vdc to 24 Vdc is acceptable.

These Hall-effect devices are available in two package styles: the SS361CT in the miniature SOT-23 surface mount package and the SS461C in the leaded, flat TO-92-style package.

The SS361CT’s small size requires less PCB (printed circuit board) space, allowing it to be used in smaller assemblies.

The SS361CT is available on tape and reel (3000 units per reel). The SS461C is available in a bulk package (1000 units per bag).
