In summary, the OP207CL has a 7mm spot size, which is unique to TT Electronics. It has a low-profile, surface mount configuration with an integrated lens. The lensing provides nearly parallel beam uniformity with a homogenous light, with very little hotspots allowing for versatile assembly in multiple applications. This product is ideally designed for encoder applications, but also works exceptionally well with multiple sensors that are designed to detect near IR LED wavelengths between 850nm and up to 940nm.
