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.

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.
