Product Overview

The Safe Series Connection – Flexi Loop is a rugged, smart safety solution designed for integration into autonomous guided vehicles (AGVs) and autonomous mobile robots (AMRs). With its aluminum housing and smart installation concept, the device enables space-saving deployment in dynamic production environments. It supports adaptive safety functions that allow AGVs and AMRs to respond instantly to real-time conditions such as personnel presence or environmental changes. By connecting via EFI-pro communication, Flexi Mobile ensures secure, standardized interaction between safety sensors, controllers, and actuators. This results in a consistent safety logic that enables intelligent, situation-specific responses—such as dynamic protective field switching—without compromising operational efficiency.

Key Features and Technology

Flexi Mobile features a rugged and smart device design optimized for efficient production processes. Its EFI-pro communication interface provides safe Industrial Ethernet connectivity, enabling real-time data exchange between safety laser scanners and other EFI-pro-compatible sensors. This standardized communication minimizes integration effort while ensuring reliable performance. The system continuously adapts safety functions based on ambient conditions, allowing AGVs and AMRs to automatically adjust speed, steering behavior, and protective fields in response to changing environments. Safety-relevant functions—such as real-time position monitoring of the vehicle and concurrent detection of people—are performed simultaneously, creating a unified safety logic that supports targeted protective measures like dynamic field switching or context-aware responses.

Technical Characteristics

The Flexi Loop is built with a rugged aluminum housing to ensure durability in demanding industrial settings. It utilizes EFI-pro communication for safe and standardized data exchange between sensors, controllers, and actuators. This enables real-time, secure interaction across the safety network. The system supports adaptive safety solutions that allow autonomous vehicles to react immediately—adjusting speed, steering behavior, and protective fields based on detected conditions. Through continuous monitoring and dynamic response, Flexi Mobile ensures consistent safety logic without requiring manual intervention or complex programming. All functions operate via a unified safety interface that maintains compliance with industrial safety standards while enabling intelligent, responsive operation.

Configuration and Integration

Flexi Mobile integrates seamlessly into AGVs and AMRs through its EFI-pro-compatible interface, connecting directly to safety laser scanners and other EFI-pro sensors over a safe Industrial Ethernet network. This enables standardized, real-time communication with minimal setup effort. The device supports the customization of mobile robots, allowing manufacturers to tailor safety behaviors according to specific operational needs. Integration is simplified by the consistent safety logic that allows simultaneous execution of multiple safety functions—such as position monitoring and human detection—without conflicts. As a result, dynamic protective field switching or situation-specific responses can be implemented efficiently during system configuration.

Operating Environment

The Flexi Loop is designed for operation in industrial environments with typical temperature ranges and exposure to mechanical stress. Its rugged aluminum housing ensures durability under vibration, dust, and impact conditions commonly found in manufacturing facilities. The device operates reliably within standard industrial settings where ambient conditions may vary due to high activity levels or dynamic movement of equipment. As long as the system adheres to safe Industrial Ethernet communication protocols and is installed according to recommended guidelines, it maintains stable performance across diverse operational scenarios.

Industrial Applications

The Safe Series Connection – Flexi Loop is ideal for use in automated logistics and material handling systems where AGVs and AMRs operate in shared spaces with personnel. It enables safe navigation by continuously monitoring vehicle position and detecting human presence, allowing immediate adjustments to speed or protective fields. This makes it suitable for applications such as warehouse automation, factory floor logistics, and flexible production lines. By supporting adaptive safety solutions, the device ensures both operational efficiency and worker safety without requiring extensive reconfiguration or additional hardware.
