Vishay Through Hole Slotted Optical Switch Phototransistor Output 24.5 x 6.3 x 10.8 mm TCST2202

Vishay TCST2202 Through Hole Slotted Optical Switch with Phototransistor Output is a compact and reliable optoelectronic sensor designed for industrial and electronic applications requiring precise object detection and optical isolation. With dimensions of 24.5 mm length, 6.3 mm width, and 10.8 mm height, it fits standard through-hole mounting footprints.

This miniature slotted switch integrates an infrared emitter and phototransistor arranged face-to-face within a leaded housing that features a daylight blocking filter to prevent interference from ambient light sources. It operates reliably across a wide temperature range from -55°C up to 85°C, making it suitable for industrial, laboratory, and manufacturing environments.

The device’s phototransistor output provides a typical output current of 2 mA under operating conditions, with fast response characteristics including a typical rise time of 10 microseconds and a fall time of 8 microseconds. The 5 mm slot width and 3.1 mm optical gap allow it to detect and interrupt light beams for encoder and counter applications.

The TCST2202 is RoHS compliant and supplied in convenient tube packaging that facilitates insertion into automated machinery or PCB assembly lines. Common use cases include optical switching, photo interrupters, counters, and optical encoder systems in automation and electronic instrumentation.

The device contains one phototransistor channel for precise optical switching. Typical rise and fall times are 10μs and 8μs respectively, ensuring fast response. Equipped with a daylight blocking filter and emits infrared light at 950 nm wavelength.

Designed to operate reliably in temperatures ranging from -55°C to 85°C. Its package is RoHS compliant and is supplied in tube packaging for easy handling. The slot width is 5 mm, and the optical gap is 3.1 mm, facilitating precise object detection or counting.

Offers a typical output current of 2 mA under test conditions (IC). Ideal for applications such as photo interrupters, counters, encoders, and optical switches.

These features make the Vishay TCST2202 a suitable optoelectronic sensor for diverse sectors like electronics manufacturing, industrial automation, HVAC control systems, and laboratory instrumentation.
