1. Product Overview: IFM AL2401 High-Precision Photoelectric Sensor
The IFM AL2401 is an advanced photoelectric sensor designed for
precise object detection and positioning in industrial automation
systems. Featuring a rugged stainless steel housing
(IP67/IP69K-rated), this sensor operates reliably in harsh
environments exposed to dust, moisture, and temperature extremes
(-30°C to +80°C). Utilizing infrared LED technology, it detects
objects of varying shapes, colors, and materials (e.g., plastics,
metals, glass) with a sensing range of 0.1–10 meters. The AL2401
offers both analog (0–10V) and digital (PNP/NPN) outputs, enabling
seamless integration with PLCs, robotics, and IoT platforms. Its
compact M18 design and adjustable sensitivity make it ideal for
high-speed automation, packaging, and material handling
applications.
2. Key Technical Specifications
- Detection Range: 0.1–10 m (adjustable via built-in potentiometer).
- Light Source: Infrared (880 nm wavelength).
- Outputs: Analog (0–10V) + Digital (PNP/NPN, 100 mA).
- Supply Voltage: 10–30V DC (±10%).
- Response Time: ≤2 ms.
- Housing Material: Stainless steel (AISI 304).
- Protection Class: IP67/IP69K (dust/water/high-pressure resistant).
- Operating Temperature: -30°C to +80°C.
- Certifications: CE, UL, IECEx, ATEX (Zone 22).
3. Industrial Applications and Use Cases
The AL2401 excels in logistics automation for detecting parcel
presence on conveyor belts and verifying pallet stacking heights.
In automotive assembly, it ensures precise positioning of
components during robotic welding or painting. Food and beverage
facilities use its IP69K-rated design for hygienic bottle cap
alignment and fill-level monitoring. The sensor’s long-range
detection suits AGV (Automated Guided Vehicle) obstacle avoidance
in warehouses, while its ATEX certification enables deployment in
explosive dust environments like grain silos or chemical plants.
Additional use cases include paper roll detection in printing
presses and part verification in CNC machining centers.
4. Competitive Advantages and Unique Features
- Multi-Material Detection: Reliably senses transparent, glossy, or dark objects.
- Dual Output Flexibility: Combines analog precision with digital switching for versatile
control.
- Extreme Durability: Stainless steel housing resists corrosion, impacts, and
washdowns.
- Fast Response: ≤2 ms reaction time for high-speed production lines.
- ATEX Compliance: Safe operation in Zone 22 hazardous areas with combustible dust.
5. Functional Capabilities and Operational Benefits
The AL2401’s analog output provides continuous distance feedback,
enabling dynamic adjustments in automated workflows, while the
digital output triggers alarms or machine shutdowns upon object
detection. Its infrared light source minimizes interference from
ambient lighting, ensuring stable performance in brightly lit
facilities. The built-in sensitivity adjustment allows fine-tuning
for challenging materials like black rubber or reflective metals.
With reverse polarity and overload protection, the sensor reduces
downtime and maintenance costs. By enhancing detection accuracy and
process efficiency, the AL2401 supports Industry 4.0 smart
manufacturing initiatives.
