TT Electronics – BI Technologies


TT Electronics has introduced a compact, infrared LED emitter which has the industry’s largest spot diameter of 7mm for reliable optical sensing and light detection in position encoders.

Offering up to 10mW total radiated power at the maximum drive current of 100mA, and a narrow 2.25° angle of half intensity, the OP207CL couples optical flux very efficiently on to the receiving photo-sensor to ensure clearly detectable on/off transitions.

Its 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.

The surface-mount LED with integral moulded lens comes mounted on a 9.9mm x 9.9mm PCB substrate. The compact footprint and height of 6.3mm allow use in space-constrained designs.

The GaAIAs LED emits wavelengths in the 840-870nm near-infrared range for good spectral matching with silicon photo-sensors, and the typical rise/fall time of 22ns ensures a fast response to On/Off signals.
