Cylindrical ultrasonic transducer TA0180KA

non-contacthigh-frequencyproximity

Product Overview
The TA0180KA 180 kHz ultrasonic transducer is designed for short-range non-contact distance measurement with a detection range of 0.1–2 m and a blind zone of less than 0.1 m. It is intended for compact position sensing, approach measurement, obstacle detection and industrial distance detection systems.

Key Features

• 0.1–2 m distance measurement: Supports short-range ultrasonic detection from 0.1 m to 2 m for compact non-contact sensing applications.
• 180 kHz ultrasonic frequency: 180 kHz ±4% center frequency for high-frequency ultrasonic measurement.
• Narrow 7° beam angle: 7° ±1° full beam angle (-3 dB) for focused detection and narrow directivity.
• Short blind zone: Blind zone less than 0.1 m, enabling measurements closer than typical lower-frequency models.
• PBT housing: Compact PBT enclosure for installation in constrained spaces.
• IP65 protection level: Dust-tight and protected against water jets for practical industrial environments.
• Tested at 25°C: Performance values referenced at 25°C; integration should consider operating conditions.

Mechanical Design
The TA0180KA features a compact PBT housing with a circular sensing face, cable outlet and short body depth. Dimensional references: front diameter ≈ Φ28 mm, body depth ≈ 13 mm, cable length ≈ 400 mm — suitable for constrained installations.

Electrical and Test Information
Specifications include admittance curve, overall sensitivity test and pointing angle curve. Overall sensitivity condition: 0 dB = 250 Vp-p, cycle: 50, 30 cm test distance using transmitter and receiver configuration. Performance values were measured at 25°C; actual integration should consider installation, temperature, target material and acoustic environment.
