One-button programmable sensors for use with glass or plastic fibers

• Fiber optic sensors for DIN rail mounting; 10 to 30V dc operation

• Visible red (680 nm) light source; models for use with either glass or plastic fibers

• High optical sensing power when needed, also excels at low-contrast sensing

• Easy TEACH-mode programming automatically adjusts sensitivity to optimal setting*

• D12E sensors are designed for low-contrast sensing applications (switching threshold set to just

above the “dark” condition)

• D12E2 sensors set their switching threshold midway between the “dark” and “light” conditions to ig-

nore subtle changes, such as web flutter

• Output may be programmed for either light or dark operate

• Fast 200 microsecond sensing response; programmable 40 millisecond pulse stretcher

• Secure one-button programming is easy to use; one button sets both TEACH and sensor configura-

tion settings

• 7-segment LED bar graph indicates relative received signal strength and sensing contrast, program-

ming status, and diagnostic trouble warnings

• Marginal sensing alarm

• Separate input allows remote programming by an external device, such as a switch or a process con-

troller

WARNING: Not To Be Used for Personnel Protection

Never use this device as a sensing device for personnel protection. Doing so could lead to serious

injury or death. This device does not include the self-checking redundant circuitry necessary to allow its

use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-

energized sensor output condition.

Overview

D12 Expert self-contained sensors offer one-button programming that provides security for your settings, yet is simple to set. D12 Expert

sensors offer two programming modes: TEACH mode and SENSOR OUTPUT CONFIGURATION mode. The D12 Expert also features
