Inductive Cylindrical sensors AH Series

Datasensing AH Series

The AH Series delivers high-precision metal detection in an ultra-compact Ø 6.5 mm cylindrical stainless-steel housing, designed specifically for demanding industrial automation tasks with restricted space. With sensing distances as short as 1.5 mm and robust performance across materials, these sensors bring exceptional reliability in compact installations. 

Design & Functionality

• Housed in a stainless-steel Ø 6.5 mm body, the AH Series fits seamlessly into tight mechanical setups or high-density actuator zones. 
• Provides very short sensing distances (≈ 1.5 mm for flush-mount models, up to ~4 mm for some non-flush versions) enabling detection of small metal parts with minimal clearance. 
• Built-in electronics with complete protection against electrical damage (reverse polarity, short-circuit auto-reset, impulse over-voltage) ensures stable operation even in harsh industrial conditions. 
• Includes 360° visible LED status indicator and IP67-rated sealing, offering clear diagnostics and industrial robustness. 

Total Crossed Beams

(In the context of the AH Series, this concept translates to a uniform detection field across the small active face rather than optical beams.)

• Maintains a consistent magnetic sensing zone even at very short distances, enabling reliable detection of metal objects regardless of their position or alignment variations.
• This leads to high repeatability and reduces missed detections or false alarms in compact installations.

Beam Pitch Options

(Here the term refers to the selectable sensing distance/resolution rather than literal beams.)

• Models offer nominal sensing distances from ~1.5 mm (flush mount) to ~4 mm (non-flush mount) depending on variant. 
• Repeat accuracy is typically < 5% and thermal drift under 10%, supporting consistent detection performance over time and temperature changes. 

Intrinsic Synchronism

• The AH Series incorporates fully integrated synchronisation and protection electronics, removing the need for external synchronisation or additional modules, thereby simplifying wiring and installation.
• Time-before-availability is very short (≤ ~50 ms), enabling rapid deployment in automated production systems. 

Operational Advantages

• High Switching Frequency: Capable of switching up to ~5 kHz, making the AH Series suitable for fast-moving metal parts in high-speed automation.
• Easy Configuration: With its compact Ø 6.5 mm size, stainless-steel body, selectable sensing distance and full protection suite, the AH Series offers easy integration into dense automation layouts.
• Applications: Ideal for electronics assembly, automotive component sensing, robotics axes, high-density material handling and compact conveyors where space is limited, incremental metal detection is required, and industrial durability is essential.
