Photoelectric Cylindrical sensors SA Series

Datasensing SA Series

The SA Series delivers a comprehensive range of photoelectric sensors in the M18 housing format, designed for versatile object detection, compact installation, and industrial robustness. With optic modes including diffuse-reflection (short, medium and long ranges), retro-reflective, polarized retro-reflective and fixed-focus, this series is suitable for many automated manufacturing applications.

Design & Functionality

• The series includes models with diffuse-reflection sensing distances from ~150 mm (short-range) up to ~1000 mm (long-range) depending on variant. 
• All models come with sensitivity adjustment via trimmer, enabling fine tuning in installation to suit target size, background and mounting distance.
• Output logic is selectable NO/NC, and the sensor supports selectable Light-ON / Dark-ON modes, giving flexibility for integration with different control systems. 
• Protection is rated up to IP67, and full electrical protection (reverse polarity, short-circuit auto-reset) ensures durable performance in dusty or industrial environments. 
• Indicator LEDs (Green for power ON, Yellow for output/status) enable easy installation verification and diagnostics. 

Total Crossed Beams

(In this photo-electric sensor context, this term maps to a consistent detection beam or field rather than literal crossed beams.)

• The SA Series ensures a stable detection zone, even when targets vary or installation clearances change, which leads to fewer missed detections or false triggers in automation lines.
• This reliability is critical in high-throughput manufacturing and conveyor systems where object position and background conditions may shift.

Beam Pitch Options

(Here interpreted as selectable sensing distance / optical variant rather than literal beam spacing.)

• Short-range diffuse variant: nominal sensing distance around ~150 mm (white target) in one model. 
• Medium range diffuse variant: nominal ~400 mm in another model. 
• Long-range diffuse variant: nominal ~1000 mm (1 m) in another model. 
• Retro-reflective / polarized versions extend the application to reflective backgrounds or longer spans (e.g., ~3 m for polarized retro in some variants). 
• This broad range of distance variants allows you to select the SA model that matches your target size, mounting clearance, background reflectivity and speed of detection — offering flexibility in system design.

Intrinsic Synchronism

• The SA sensors are self-contained: no external synchronisation or complex wiring is needed to ensure proper operation, which simplifies installation.
• With time-before-availability (startup) typically ≤ 200 ms and switching frequency up to ~1 kHz in typical models, the series supports responsive automation use. 

Operational Advantages

• Broad optical flexibility: Whether you need short-range, medium-range or long-range diffuse detection, or retro-reflective/polarized detection for reflective backgrounds, the SA Series covers it all.
• Selectability & adjustability: With trimmer sensitivity adjustment, selectable NO/NC outputs, and Light/Dark mode capability, the series adapts to varied control logic and installation conditions.
• Industrial durability in compact package: M18 housing, high protection rating, and robust electrical features make the SA Series well-suited for manufacturing, packaging, conveyors and automation systems with industrial reliability.
• Applications: Ideal for object-presence detection in general manufacturing, part sorting on conveyors, packaging lines with reflective backgrounds, machine tool feeding, intralogistics where flexible detection, compact mounting, and reliable performance are required.
