Description:

These Hall-effect devices contain a monolithic integrated circuit which incorporates a Hall element, a linear amplifier, a threshold amplifier, and Schmitt trigger on a single Hallogic? silicon chip. Included on-chip is a band gap voltage regulator to allow operation with a wide range of supply voltages. The devices feature logic level output and provide up to 21 mA of sink current. This allows direct driving of more than 7 TTL loads or any standard logic family using power supplies ranging from 4.5 to 24 volts. Output amplitude is constant at switching frequencies from DC to over 200 kHz.

Features:

? Designed for non-contact switching operations

? Operates over broad range of supply voltages (4.5 V to 24 V)

? Operates with excellent temperature stability in harsh environments

? Drive capability up to 7 TTL loads

Applications:

? Non-Contact Reflective Object Sensor

? Assembly Line Automation

? Machine Automation

? Machine Safety

? End of Travel Sensor

? Door Sensor
