Inductive Cylindrical sensors VT Series

Datasensing VT Series

The VT Series delivers reliable metal-object detection designed specifically for AC-powered industrial automation systems. With a rugged M30 housing, multivoltage AC operation (20…250 V AC) and both flush & non-flush mounting variants, the VT Series offers high reliability in standard and demanding manufacturing environments. 

Design & Functionality

• The sensor is housed in a nickel-plated brass M30 × 1.5 cylinder, providing robust mechanical strength and compatibility with standard M30 mounting. 
• Supports AC multivoltage range of 20…250 V AC / 50-60 Hz, enabling integration into mains-powered systems without a separate DC supply. 
• In un-shielded (non-flush) versions, nominal sensing distance reaches ~15 mm (for standard target 45×45 mm FE360) while flush (shielded) versions deliver around ~10 mm nominal distance (for target 30×30 mm FE360). 
  • Correction factors for metals: copper 0.40-0.45, aluminium 0.50, brass 0.55-0.60, stainless steel 0.75-0.80. 
• Electrical features: repeat accuracy < 5%, thermal drift < 10%, switching type TRIAC output, switching frequency ~25 Hz (AC models) for reliable detection in varied industrial applications. 

Total Crossed Beams

(Here meaning a consistent detection field across the active face rather than literal optical beams.)

• The VT Series maintains a stable sensing zone across its active face even in AC installations with varied background metal and mounting clearance.
• This results in repeatable detection performance and reduces the likelihood of missed detections in infrastructure where mounting conditions vary.

Beam Pitch Options

(Here interpreted as selectable sensing distances and mounting style rather than literal beam pitch.)

• Flush (shielded) version: ~10 mm nominal sensing distance; Operating distance 0…8.1 mm (example) for target 30×30 mm FE360. 
• Non-flush (un-shielded) version: ~15 mm nominal sensing distance; Operating distance 0…12.1 mm (example) for target 45×45 mm FE360. 
• Shielded vs un-shielded options allow the sensor to adapt to either tight-clearance mounting or longer-distance detection needs.

Intrinsic Synchronism

• The electronics are fully integrated — the sensor works with 2-wire connection and no external synchronisation wiring is required.
• Time-before-availability is ≤ 200 ms typical — enabling the sensor to be quickly ready after power-up. 

Operational Advantages

• AC‐Voltage Compatibility: With 20…250 V AC input, the VT Series integrates into mains-powered automation systems without extra power conversion.
• Large Detection Range: With up to ~15 mm nominal sensing (un-shielded), these sensors suit larger metal targets or increased mounting clearance.
• Robust Design & Reliable Detection: With metal correction factors, stable detection field and standard industrial protection (IP67), these sensors deliver dependable performance in general manufacturing, metalworking and assembly lines.
• Applications: Ideal for metal-object presence detection on AC-powered conveyor systems, manufacturing machines, automated assembly lines and general industrial use where metal parts, AC supply, and industrial robustness are required.
