Omron NX-RS1201 Load Cell Input Module

The RS1201 Omron is a high-precision load cell input module for the NX I/O system, offering 24-bit resolution and a fast 125 µs conversion time. Designed for integration with Sysmac automation platforms, it supports a single strain gauge load cell with differential input in the ±5.0 mV/V range, making it ideal for weighing, force, and tension control applications.

With a slim 12 mm-wide DIN rail profile, screwless push-in wiring, and free-running or synchronous processing, this module is a perfect fit for compact, high-speed measurement systems.
