RH200 Linear Encoder System

Overview

RH200 LINEAR ENCODER SYSTEM OVERVIEW

RH200 Encoder System

PBA RH200 linear encoder system is a non-contact optical encoder designed for position feedback solution.

The system uses a common reflective tape scale scanned by a readhead chosen from a range of options offering industry standard digital square wave or analogue sinusoidal output signal formats.

Its unique patented optical scheme is used in all readhead series to provide high tolerance to scale contamination.

RH200 is an ideal feedback solution wherever precision controlled movement is required.

The RH200 readheads compact size and low mass makes the system ideal fr small XY stages and actuators.

An integral set-up LED enables quick and easy installation Common applications include semiconductor/electronics manufacturing and inspection, coordinate measuring and layout machines, height gauges, linear motors, pre-press printing and variety of custom linear motion solutions.

*Only sold together with PA linear products. Not available for individual sales.
