NEW PRODUCT NEWS—edited by Rick Prescott

Transmissive Optical Sensor

A new transmissive optical sensor featuring unique horizontal slot construction is now available. With a 0.5-mm aperture, the TCST5250 is optimized for high-accuracy sensing of horizontal-moving objects in shaft encoders, VCRs, data storage equipment, the code wheels of DC motors, and other space-limited products. Housed in a plastic polycarbonate package with a height of only 9 mm, the device provides a 2.7-mm gap and a lead pitch of 2.54 mm. As a transmissive sensor, it is further optimized for use in compact end product designs through the direct face-to-face positioning of an infrared emitter and phototransistor detector on the same optical axis.

The sensor features an operating wavelength of 950 mm, with a 0.4-mm resolution and a typical current transfer ratio of 7.5%. The device is designed with a positioning pin that ensures high-accuracy assembly. Additionally, the device provides protection against ambient light with an integrated daylight filter that significantly reduces light interference.

With a fast switching speed and new horizontal slot construction, the transmissive optical sensor keeps pace with todayıs market demand for smaller, high-performance equipment and is ideal for designers who need high-precision switching in even the most space-constricted products.

Prices starts at $41 for 100 pieces.
