Technical Specifications

The LS7184-S typically operates from a 5V supply and is compatible with standard TTL and CMOS logic levels. The maximum input frequency is determined by the encoder resolution and the desired speed of operation. The output signals provide a clock pulse for each quadrature transition and a direction signal indicating the direction of movement. The operating temperature range is typically between -40°C and +85°C, making it suitable for industrial environments. The specific resolution and accuracy depend on the connected encoder.
