Inductive Cylindrical sensors AA1 Series

Datasensing AA1 Series

The AA1 Series delivers precision inductive detection in an incredibly compact Ø 3 mm housing—designed for installations where space is at a premium. With a nominal sensing distance down to 0.6 mm and high switching frequency, these sensors ensure reliable detection in ultra-tight spaces such as electronics assembly, automotive components and small-part automation.

Design & Functionality

• With a Ø 3 mm stainless-steel (AISI 303) body and a length of only ~22 mm, the AA1 fits into the most constrained mounting scenarios. 
• Nominal sensing distances of 0.6 mm or 1 mm make this series capable of detecting extremely small targets in flush-mount or non-flush mounting conditions. 
• Built-in ASIC electronics provide high reliability and repeatability—the series is designed for industrial durability even in compact form. 
• Standard features include IP67 protection, reverse-polarity protection, short-circuit auto-reset, and high immunity to ripple—supporting consistent operation in harsh environments. 

Total Crossed Beams

(In inductive sensors, this concept equates to a very stable and uniform detection field across the sensor face.)

• The AA1’s detection field remains consistent even at extremely small sensing distances, enabling reliable detection of micro-parts or close-proximity metal targets.
• This ensures precise detection performance even when space is highly constrained or background surfaces vary.

Beam Pitch Options

(Translated here to the selectable sensing distances and precision rather than optical beams.)

• With sensing distances starting at ~0.6 mm (for ultra-short targets) and up to ~1 mm (for slightly larger clearance) the AA1 series supports very tight-clearance detection. 
• Repeat accuracy is <5% and thermal drift is <10% in many models, enabling stable performance over time and temperature variation. 

Intrinsic Synchronism

• The electronics are fully integrated—no external synchronising wiring is needed, and the sensor is ready for operation once powered. 
• Time-before-availability is typically ≤ 50 ms, supporting fast-start installations. 

Operational Advantages

• High Switching Frequency: Up to ~3 kHz in certain models, enabling detection of very fast-moving metal targets in high-speed automation environments.
• Easy Configuration: Provided in compact form with minimal complexity, the AA1 is optimised for flush or near-flush mounting in tight mechanical setups.
• Applications: Ideal for electronics manufacturing, automotive component sensing, robotics arms, micro-assembly and any automated system where miniaturised form-factor, very short detection distance, and industrial robustness are required.
