Cylindrical ultrasonic transducer TA0040KB

non-contactfor level measurementproximity

Product Overview
The TA0040KB is a 40 kHz ultrasonic transducer engineered for non-contact distance measurement and industrial sensing. It supports reliable detection from 0.35 m up to 10 m with a blind zone below 0.35 m. The unit is designed for fixed screw installation and offers an IP65 protection rating for use in industrial environments.

Key Features

• Detection range: 0.35–10 m for medium-range distance sensing.
• Operating frequency: 40 kHz ±2.0 kHz with a 3.0 kHz bandwidth for stable response.
• Beam pattern: 14° ±2° full beam angle for focused measurement.
• Low blind zone: < 0.35 m.
• Protection: IP65 rated housing for dust and water resistance.
• Mounting: Screw-fixed design with M20 × 1.5 thread.
• Cable: Standard 2 m cable supplied; length customizable on request.

Typical Applications

• Positioning and object detection
• Approach and proximity measurement
• Traffic and vehicle detection
• Obstacle avoidance systems
• Distance and level measurement
• Industrial automation and process sensing

Mechanical Design
The TA0040KB features a cylindrical housing sized Φ68 × 95 mm with a threaded cylindrical body and front sensing surface. Case material: PVC. Installation is by screw fixing (M20 × 1.5). Protection rating: IP65. Standard cable length: 2 m (customizable). Weight: 380 g.

Electrical and Wiring Information
Sensitivity test condition: 400 Vp-p emission, 50 periods, test distance 1.5 m. Wire color coding: red = positive, white = negative, green = shielding; two thinner wires for the thermistor. Specifications include resistance, phase angle, sensitivity and directivity curves (refer to technical documentation). Maximum working voltage: 1800 Vp-p (pulse, 2% duty cycle).
