Surface-mount IR LED emitter generates uniform light for precision
Uniform, parallel light output for high-precision applications is provided by the OP207CL infra red LED emitter, says TT Electronics.
The compact LED emitter has the industry’s largest spot diameter of 7.0mm, says TT Electronics, for reliable optical sensing and position encoder applications.
With up to 10mW total radiated power at the maximum drive current of 100mA, and 2.25 degree angle of half intensity, the OP207CL couples optical flux extremely efficiently onto the receiving photo-sensor to ensure clearly detectable on/off transitions. The integrated collimating lens creates a tight beam profile for use with accuracy-dependent devices such as radial or linear encoders for absolute or incremental measurement. They can also be used as well as long-range light curtains, edge detectors, scanners, and general optical sensing and switching.
The wide operating temperature range is -40 to +105 degree C, means the OP207CL can withstand demanding environments in a range of applications including industrial automation, safety systems, robotics, security detectors, or other equipment which requires dependable position, proximity, or motion sensing.
The surface-mount LED with integral moulded lens is mounted on a 9.9 x 9.9mm PCB substrate. The footprint and height (6.3mm) mean it can be used in space-constrained situations. The GaAIAs LED emits wavelengths in the 840 to 870nm near-infra red range for good spectral matching with silicon photo-sensors, and the typical rise/fall time of 22 nano seconds ensures fast response to turn-on/off signals.
TT Electronics’ OP207CL LEDs are available now, and shipped in plastic trays for protection during transit and storage.
