D12 Expert Series –
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 ignore 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 configuration settings
• 7-segment LED bargraph indicates relative received signal strength and sensing
contrast, programming status, and diagnostic trouble warnings
• Marginal sensing alarm
• Separate input allows remote programming by an external device, such as a
switch or a process controller

Page 2: Teach Mode
Models are available for either glass or plastic fiber optics (see page 1). Fiber optics are purchased separately to fit your exact sensing application. A few representative fiber optic styles are listed on pages 11 and 12. See the Banner Photoelectric Sensors Catalog for the full selection of fiber optic assemblies. - Page 3 D12 Expert Series D12E and D12E2 models set their sensing threshold points differently during the Max. Light Signal TEACH mode process. D12E sensors automatically place the switching threshold just above the dark condition that is taught to the sensor (see Figure 2). This scheme Light Sensing Condition works exceptionally well for sensing a very small sensing contrast, where the light...

Page 4: Machine-Guard
Systems, and other systems so designated, are designed to meet OSHA and ANSI machine safety standards for point-of-operation guarding devices. No other Banner sensors or controls are designed to meet these standards, and they must NOT be used as sensing devices for personnel protection. - Page 5 D12 Expert Series D12 Expert Dimensions D12 Expert Series – Glass Fiber Optic Models Glass Fiber Installation: Fiber-retaining Clip (Supplied with Sensor) 12.0 mm A.

Page 7: Output Configuration
D12 Expert Series Output Configuration Programming Programming is performed using the push button and a combination of single-, double-, and triple-clicks. (For a description of these clicks, see Remote Programming Light/Dark on page 9). Two output functions may be programmed by the push button: Operate Indicators 1. - Page 8 D12 Expert Series TEACH-Mode Programming Sensitivity is automatically set (and optimized) by “teaching” the sensor the light and dark conditions, in TEACH mode. TEACH mode is accomplished by presenting each of the two sensing conditions to the fiber optics. They may be presented in either order (LEDs flash 3 (the light condition first, then the dark, or vice versa).

Page 9: Remote Programming
D12 Expert Series Remote Programming To remotely program the TEACH and OUTPUT CONFIGURATION modes, connect the sensor’s gray wire to a remote programming switch. (This input parallels the push button on the sensor, so the push button sequences explained on the previous two pages also apply for a remote switch.) Connect a remote programming switch between the gray wire and dc common (see hookup diagrams on page 6). -
Page 10: Self-Diagnostics
D12 Expert Series Self-diagnostics D12 Expert sensors provide several self-diagnostic functions. One or more flashing LEDs on the 7-segment display indicates a trouble condition. In addition, an alarm output warns of marginal sensing conditions. The D12 Expert’s 7-segment display indicates four problems: Display: LED #7 flashes and green ON indicator is ON steadily. - Page 11 (one for each size and type) are indicated, along with the maximum range for each (expect less range for fiber assemblies with angled sensing ends).
