Product Overview

The SICK EG34x Absolute Encoders are precision-engineered position sensors designed for reliable, high-accuracy position detection in demanding industrial environments. These encoders provide absolute position feedback with a working range of 3,400 revolutions, ensuring consistent performance even after power loss. Built with robust mechanical and electrical design, the EG34x series delivers precise switching points with repeatability of less than 20° (standard deviation σr< 20°), making them ideal for applications requiring reliable position tracking without continuous power. With a compact form factor and IP65/IP67 protection rating, these encoders offer excellent resistance to dust and water ingress, ensuring durability in harsh conditions. The product weighs 1.3 kg and is designed for integration into automation systems where high reliability and long-term stability are essential.

Key Features and Technology

The EG34x absolute encoders feature independently adjustable switching points, enabling precise customization of output signals to match specific application requirements. The switching hysteresis is less than 150°, minimizing false triggering during mechanical movement or vibration. A cam length of 1,150 revolutions ensures smooth and reliable switching over extended operational cycles. The encoders are constructed with a high-performance design that includes resistance to shocks up to 30 g (single shock) and 10 g (continuous), as per EN 60068-2-27 standards. This makes them suitable for dynamic environments where mechanical stress is common. The technology ensures consistent performance across operating conditions, with a repeatability of less than 20°, supporting accurate position feedback in critical automation tasks.

Technical Characteristics

The SICK EG34x absolute encoders operate within an ambient temperature range of 0 °C to +70 °C and can be stored between 0 °C and +85 °C. They are supplied with a maximum operating voltage of ≤24 V DC, compliant with class III protection (DIN EN 61140), ensuring safe operation in industrial settings. The encoders have a permissible radial shaft load of 200 N, allowing them to withstand mechanical stress during operation. With an IP65/IP67 rating (IEC 60529), they are fully protected against dust and water jets or immersion, depending on the environment. The product features standard connectors and cables for easy integration into existing systems, ensuring compatibility with a wide range of control and drive technologies.

Configuration and Integration

The EG34x encoders offer flexible configuration through independently adjustable switching points, allowing users to tailor output signals to match specific process requirements. The standard connector and cable setup simplifies integration into automation systems using existing control interfaces. These encoders are designed for direct connection with PLCs or motion controllers, enabling real-time position monitoring without additional signal conditioning. Their compatibility with standard industrial power supplies (≤24 V DC) ensures seamless deployment in a variety of production environments. The modular design and straightforward wiring make them easy to install and maintain, reducing integration time and operational downtime.

Operating Environment

The EG34x absolute encoders are designed for reliable operation within an ambient temperature range of 0 °C to +70 °C. They can be stored in temperatures ranging from 0 °C to +85 °C, ensuring stability during transport and long-term storage. The IP65/IP67 rating provides full protection against dust ingress and water jets or temporary immersion, making them suitable for use in outdoor or wet environments such as manufacturing lines, material handling systems, or exposed machinery. The encoders are also tested to withstand mechanical shocks of up to 30 g (single shock) and 10 g (continuous), ensuring resilience during dynamic operations. These environmental capabilities support reliable performance across diverse industrial settings.

Industrial Applications

The SICK EG34x absolute encoders are ideal for use in applications requiring precise position feedback, such as robotic arms, conveyor systems, and automated assembly lines. Their high repeatability and low switching hysteresis ensure accurate detection of position changes even under vibration or load variations. The robust construction and environmental protection make them suitable for use in harsh industrial conditions where reliability is critical. Applications include machine tool positioning, packaging equipment, and material handling systems where consistent motion control is essential. With a working range of 3,400 revolutions and a cam length of 1,150 revolutions, the EG34x provides reliable performance over extended operational cycles in high-precision automation environments.”}
