Surface-Mount Sensors are AEC Q101 Qualified, MSL1 Rated

Vishay Intertechnology’s TC*T1300X01 devices are 950nm transmissive (interrupter) optical sensors qualified to the AEC Q101 standard, suiting them for use in automotive applications. In addition, these surface mount sensors have a Moisture Sensitivity Level rating of 1 (MSL1), conferring an unlimited floor life.



Transmissive sensors are also known as interrupter sensors. They contain an infrared emitter and detector mounted facing each other and separated by a small gap. An object such as an encoding wheel passes through the gap between the emitter and detector and interrupts the passage of light, allowing the sensor to detect the object’s presence. A common automotive switch application is gear shift position detection.

The TCPT1300X01 is a single-channel sensor, while the TCUT1300X01 is a dual-channel variant. Aperture size for both devices is 0.3mm, and the spacing gap is 3.0mm. This allows them to be used with a wide variety of materials, and permits looser mechanical tolerances than other solutions, making them well-suited for automotive and industrial applications.

The TC*T1300X01 series offers a wide operating temperature range of -40°C to +85°C. The devices are RoHS-compliant, free of halogens, and compatible with lead (Pb)-free soldering.

The sensors can be used with an encoding wheel to determine rotary position and velocity, or with a linear code strip to sense linear position and velocity. With dual channels, the TCUT1300X01 can also be used to detect direction and is commonly used for steering wheel optical encoding. For example, an electronic stability control system relies on the critical output of speed, position, and direction of the steering wheel, as determined by the encoder, to help drivers on icy or wet roads. In electric power steering (EPS), the transmissive sensor plays a role in providing steering wheel speed, position, and direction as inputs to a larger system using an assist motor to replace the traditional hydraulic power steering pump.

MSL-1 rating is important for both automotive and industrial manufacturers. Typical optical devices, like visible LEDs, have an MSL4 rating and must be assembled within 72 hours of opening the reel packaging. MSL1 rating eliminates the need for special handling and storage.
