The FX-11A is an analog fiber optic sensor that is perfect for applications that require basic measurement of work pieces. The 1-5V output can be interfaced with various equipment such as the CA2 control unit for advanced calculations including height evaluation or level detection by differential sensing.

The slim size of the amplifier as well as the built-in interference prevention function allow for mounting multiple sensors in close proximity. Convenient indicators on the amplifier include an incident beam indicator, where the brightness fluctuates in proportion to the incident beam intensity, and a saturation indicator that illuminates when the output reaches 5V.
