TECHNOLOGY

ROUNDUP

Infineon’s KP 126 combines high precision with low cost in miniaturised SMD packaging. An integrated signal-conditioning circuit fabricated in BiCMOS technology performs the sensing function using a surface-micromachined array of capacitive sensors, amplifies the sensor cell output then compensates and linearises the temperature using a third order, polynomial transfer function. The resulting output voltage is proportional to the applied pressure.

Features

UCapacitive absolute pressure sensor

URatiometric analogue output

UCalibrated transfer function

UClamping

UHigh accuracy over a wide temperature range

UMaximum error: ±1.0kPa

U‘Green’ eight-pin SMD package

UOnboard diagnostics for broken wire detection

Vishay Intertechnology’s surface mount TC*T1300X01 devices are 950nm transmissive (interrupter) optical sensors that are AEC Q101 qualified and rated for automotive applications. A 3mm gap enables looser mechanical tolerances than other solutions and a Moisture Sensitivity Level rating of 1 (MSL1) confers an unlimited floor life. The TCPT1300X01 is a single channel sensor and the TCUT1300X01 has two channels. Aperture size for both devices is 0.3mm with 3.0mm spacing gap, suiting them for use with a wide variety of materials and automotive and industrial applications. The TC*T1300X01 series offers a wide operating temperature range of -40°C to +85°C.
