Cylindrical ultrasonic transducer TA0125KC

non-contacthigh-frequencyproximity

Product Overview
The TA0125KC 125 kHz ultrasonic transducer is engineered for mid-range non-contact distance measurement with a measuring range of 0.2–3 m and a blind zone below 0.2 m. The sensor is suitable for locating, approach measurement, traffic sensing, obstacle avoidance, robot perception and compact industrial detection systems. It features a compact φ25 × 25 mm housing, IP65 protection and a standard 2 m cable that can be customized.

Key Features

• 0.2–3 m measurement range — Non-contact distance detection for short- to mid-range applications.
• 125 kHz center frequency — High-frequency ultrasonic operation for stable distance sensing.
• 14° ±2° beam angle — Focused directional detection for improved target discrimination.
• Compact φ25 × 25 mm housing — Small footprint for space-constrained installations.
• IP65 protection — Dustproof and water-resistant for industrial environments.
• Circle fixed installation — Designed for circular mounting in sensor assemblies.
• Customizable cable length — Standard 2 m cable; length adjustable on request.

Typical Applications

• Object locating
• Flow and approach measurement
• Traffic and vehicle detection
• Obstacle avoidance
• Robot sensing and navigation
• Compact short-range distance measurement systems

Mechanical Design
The TA0125KC uses a cylindrical sensor body (φ25 × 25 mm) with an ABS or aluminum-alloy shell. The compact design supports circle fixed installation and lightweight mounting (approx. 20 g). The unit meets IP65 protection and includes a standard 2 m cable; cable length and connector options can be customized to application requirements.
