D12 Series Sensors
D12 Series Sensors
Standard,
high-speed and
high-power sensors.
• Models for use with Banner
glass fibre-optic assemblies
• Standard models have fast 500 µs
(0,5 ms) output response; high-speed models
(model suffix “Y” or “Y1”) have selectable 500 or
50 µs response
• Choice of either NPN (sinking) or PNP (sourcing)
complementary outputs; 150 mA output load
rating
• Normally closed output of standard models may
be wired as a diagnostic alarm output to alert
personnel of marginal sensing conditions*
• 7-segment LED bar-graph** indicates: received
signal strength, output overload, and marginal
signal strength (note: bar-graph is inoperative in
the 50 µs mode of high speed models)
• Separate LED indicators for sensor power and
output status
• “Y1” suffix high-speed models include a 20 ms
output pulse stretcher
• Choose models with integral 2 m cable or
150 mm pigtail quick-disconnect (8 mm); 9 m
cables are also available
D12 Expert TEACH-mode fibre-optic sensors.
• 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 “dark” and “light” conditions to
ignore subtle changes, such as web flutter
• Models for glass fibre-optics available in all
versions
• Fast 200 µs sensing response; a 40 ms pulse
stretcher may be programmed, when required
• Output may be programmed for either light- or
dark-operate
• Secure one-button programming is easy to use;
one button sets both TEACH and sensor
configuration settings
• Separate input for remote sensor programming by
external switch or a PLC
• 7-segment LED bar-graph** indicates relative
received signal strength and sensing contrast,
programming status and diagnostic trouble
warnings
• Dedicated alarm output for signaling marginal
sensing conditions
AC-coupled sensors.
• Highly sensitive to very small signal change; fast
response
• Automatic gain control circuit continually adjusts
emitter output to maintain system gain
• Ideal for low-contrast applications such as web
flaw, thread break and falling part detection
• Bi-polar outputs: one NPN (sinking) and one PNP
(sourcing)
• LED indicators for sensor power, output status
and AGC lock condition
• Selectable light- or dark-operate; no false pulse on
power-up
• Adjustable output pulse time
