A new reflective optical sensor capable of detecting objects at operating distances of up to 40 mm is now available. The surface-mount TCND5000 reflective sensor, which includes an IR emitter and PIN photodiode in a single package, is well suited for use in object presence sensors, touch sensors, and proximity sensors in a broad range of consumer, industrial, and automotive applications.

With high sensitivity and an operating distance from 2 mm to as great as 40 mm, the highly integrated TCND5000 sensor offers designers a compact and reliable solution for enhancing the performance of electronic systems such as cell phones, in which the device compensates for the proximity of your ear and adjusts the volume of the speakerphone function accordingly.

The sensor’s high-intensity IR emitter features an operating wavelength of 950 nm, while a 950-nm IR band-pass filter eliminates interference from daylight. An optical barrier between the emitter and detector reduces crosstalk to very low levels.

The TCND5000 sensor is 6 mm × 3.76 mm × 3.9 mm (h). The WEEE-compliant sensor is a restriction of hazardous substances (RoHS) device. It meets JEDEC level 4 standards and are available in a lead-free, surface-mount-style package. The sensor is designed for IR reflow soldering with a peak temperature of 260°C; therefore, it’s suitable for lead-free solder processes.

Pricing in 50,000-piece quantities starts at $75 per 100 pieces.
