Industrial Applications

1. Machine Safeguarding in Wood Processing Environments

This evaluation unit, paired with USi-safety ultrasonic transducers, provides reliable safety zone monitoring for machinery in environments prone to high levels of wood dust or other airborne particles. Its ultrasonic technology overcomes the limitations of optical sensors, which are often compromised by such contaminants, ensuring consistent personnel protection without false alarms.

Problem Solved

Mitigates false alarms and machine downtime caused by dust, sawdust, or other particles that typically interfere with traditional photoelectric safety devices in harsh industrial settings.

2. Lateral Collision Avoidance for Autonomous Guided Vehicles (AGVs)

Integrated into AGV systems, this evaluation unit enables robust lateral collision protection for autonomous transport vehicles, especially those carrying long loads that require wide turning radii. Its PL d and Category 3 safety ratings ensure critical safety functions, while the ability to use multiple transducers without cross-talk and its IP65 rating make it ideal for dynamic, potentially rugged factory or warehouse environments.

Problem Solved

Ensures reliable, non-contact lateral collision protection for AGVs of various sizes in complex industrial settings, preventing accidents with personnel and other equipment, even where optical sensors may be hindered by object material, surface, or color.

3. Outdoor Safety Zone Monitoring in Logistics and Construction

The USI-F262-2E5-V19-S2D3, with its IP65 protection and wide operating temperature range (-30 to 50 °C), is well-suited for defining and monitoring safety zones in outdoor logistics hubs, construction sites, or other semi-exposed industrial areas. Its ultrasonic sensing capabilities are resilient to adverse weather conditions like fog, rain, or dirt, which can impair optical sensing technologies, providing consistent safety supervision.

Problem Solved

Provides dependable safety zone monitoring in outdoor or challenging environmental conditions where traditional optical sensors often fail due to weather elements (e.g., fog, rain, strong sunlight) or airborne debris, thus maintaining operational safety and preventing unauthorized access or equipment hazards.
