Inductive Cylindrical sensors VK Series

Datasensing VK Series

The VK Series delivers dependable metal-object detection in AC-powered industrial environments. With its multivoltage AC operation, M18 cylindrical format, and robust design, these sensors ensure consistent detection performance in standard manufacturing and automation systems.

Design & Functionality

• The series is housed in a nickel-plated brass M18 × 1 body, providing durable mounting in industrial environments. 
• Operates over a wide voltage range of 20…250 V AC / 50…60 Hz, enabling integration in AC mains-powered applications without DC conversion.
• Available sensing distances: ~5 mm (shielded / flush mount) and ~8 mm (unshielded / non-flush mount), enabling flexibility in clearance and mounting. 
• Correction factors for common metals: copper 0.35, aluminium 0.40-0.45, brass 0.50-0.55, stainless steel 0.80-0.95 — supporting material-specific detection tuning. 
• Repeat accuracy is < 5% and thermal drift of Sr < 10% for many models, delivering stable detection across temperature changes. 
• Built-in protections include multivoltage support, IP67 rating, and standard industrial reliability features. 

Total Crossed Beams

(In the inductive sensor context, this concept corresponds to a consistent magnetic detection field across the active face rather than literal optical beams.)

• The VK Series maintains a stable sensing zone, even when mounted flush or with slight background variation, allowing reliable detection of metal parts in standard setups.
• This ensures repeatable performance and fewer missed detections in AC-powered automation systems.

Beam Pitch Options

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

• Models include ~5 mm nominal for flush mounting and ~8 mm for non-flush mounting—giving you the flexibility to select based on target size or mounting clearance. 
• Example standard target sizes: 18 × 18 mm FE360 for 5 mm model; 24 × 24 mm FE360 for 8 mm model. 

Intrinsic Synchronism

• Internal electronics handle AC multivoltage input and standard output switching (TRIAC in AC models) with no requirement for external synchronising wiring—simplifying installation. 
• Time-before-availability is ≤ 200 ms in many versions, enabling rapid system start-up.

Operational Advantages

• AC-Voltage Compatibility: The broad AC voltage range (20–250 V AC) allows use directly in mains powered automation systems—no separate DC supply required.
• Standard Form-Factor & Mounting: The M18 housing and guard against standard metal detection tasks in manufacturing make it a flexible choice.
• Reliable Metal Detection: With correction factors, repeat accuracy and robust design, the VK Series delivers dependable detection across varied metal types and mounting conditions.
• Applications: Ideal for metal-object presence detection in general manufacturing lines, automated assembly, conveyor systems powered by AC mains, packaging and metal-component detection where metal parts, AC supply, and industrial reliability are required.
