Plate ultrasonic transducer TA0112KA

non-contacthigh-frequencyfor level measurement

Product Overview
The TA0112KA is a compact 112 kHz ultrasonic transducer engineered for short-range non-contact distance measurement. It provides a detection range of 0.2–4 m with a blind zone <0.2 m and is suitable for position sensing, approach measurement, obstacle detection and compact industrial distance systems. Key acoustic and mechanical parameters include 112 kHz ±4% central resonance frequency, 8 kHz bandwidth, 14° ±2° beam angle, IP65 protection and an ABS housing.

Mechanical Design
The sensor uses a compact ABS housing with a circular sensing face and cable outlet, designed for installations with limited space. Approximate dimensions: front diameter Φ25 mm, inner diameter Φ20 mm, body depth 12 mm. Mechanical layout supports embedded mounting and straightforward cable routing.

Electrical and Test Information
Specification and performance data include frequency-total resistance, frequency-phase angle, pointing angle and sensitivity curves. Sensitivity test condition: 200 Vp-p transmitting voltage, 50 periods, 20 cm test distance. Performance values are measured at 25 °C; integration must consider actual installation conditions, temperature, target material and acoustic environment.

Why Choose the TA0112KA
A compact 112 kHz ultrasonic distance sensor offering a short blind zone, focused 14° beam angle, IP65 protection and ABS housing for reliable short-range non-contact measurement where higher-frequency ultrasonic operation is required.
