Details

Built for long-range robotics distance measurement, the PLS-K2000 combines a compact footprint with UART TTL 3.3 V output for easy controller integration.


UART serial data at TTL 3.3 V makes the module a straightforward fit for Arduino, Raspberry Pi, PLC, and MCU-based designs.

Mechanical sizing and pin mapping help speed up enclosure layout and wiring for TX/RX, power, and control signals.
