SICK S30A-6011EA S3000 Standard Safety Laser Scanner

The SICK S30A-6011EA (order number 1023548) is an S3000 Standard safety laser scanner designed for stationary and mobile hazardous area monitoring. This device provides a protective field range of 3 meters and a warning field range of 49 meters, making it suitable for applications such as automated guided vehicle collision avoidance, machine access protection, and perimeter guarding. The scanner uses optical time-of-flight measurement to detect objects within its 190° scanning angle, generating up to four configurable field sets for flexible protection zones. Certified to Type 3 (IEC 61496) and Performance Level d (ISO 13849-1), the S30A-6011EA provides reliable safety functions for industrial machinery. The S3000 series is known for its compact design, easy configuration, and robust performance in demanding industrial environments.

Technical Specifications

The S30A-6011EA features a protective field range of 3.0 meters, with resolution configurable from 30 mm to 150 mm. The warning field range extends to 49 meters. The scanning angle is 190°, providing wide-area coverage suitable for most mobile and stationary applications. Angular resolution is 0.5° or 0.25° depending on range. The response time is 60 ms base response time, with a configurable multiple sampling function to adjust response time for increased safety. The scanner includes multiple configurable field sets: up to 4 field sets, each containing up to 8 fields for flexible zone switching. The simultaneous monitoring of up to 2 protective fields per field set is possible. Data transmission is via PROFIBUS or RS-422 serial interface. Supply voltage is 24 V DC. The device is housed in a robust IP65-rated enclosure suitable for indoor and outdoor applications. Dimensions are approximately 185 mm × 155 mm × 160 mm, with a weight of 3.71 kg. A 100 mm protective field supplement is required to prevent undetected approaches below the scanning plane.

Safety Functions and Configuration

The S30A-6011EA is configured using SICK Safety Designer software, which allows users to define protective and warning fields, set field switching conditions, and configure safety functions such as restart interlock and multiple sampling. Up to 4 field sets can be defined, with each set containing up to 8 fields. Field sets can be switched dynamically based on vehicle speed, direction, or machine state, allowing the scanner to adapt to changing operational conditions. The simultaneous monitoring of two protective fields per field set provides enhanced protection by allowing, for example, a near field for immediate stopping and a far field for speed reduction warnings. The restart interlock function ensures that a hazardous condition cannot restart automatically after the protective field is cleared, requiring a manual reset. The multiple sampling function adds additional samples before switching outputs, improving noise immunity at the cost of increased response time.

Applications

The S30A-6011EA is used in both stationary and mobile industrial safety applications. In stationary applications, it protects access to hazardous areas such as robotic cells, packaging machinery, and automated storage systems. In mobile applications, it is used for AGV (automated guided vehicle) and AGC (automated guided cart) collision avoidance, providing a protective field in the direction of travel and warning fields on the sides. Other applications include perimeter protection around large machinery, area monitoring of high-risk zones, and material handling systems where personnel access must be restricted during machine operation. The 49 m warning field range is particularly useful for AGV applications where early detection of obstacles allows speed reduction rather than emergency stop, improving overall system efficiency. The scanner's wide scanning angle and multiple field sets make it suitable for complex layouts and irregular shapes, such as irregularly shaped workspaces or non-rectangular machinery.

Installation and Maintenance

The S30A-6011EA is mounted using the supplied mounting bracket. Proper installation requires careful attention to the 100 mm protective field supplement: objects below the scanning plane that are less than 100 mm in height may not be detected unless additional measures (such as the use of a protective field supplement) are taken. The scanner's sensing plane must be set at a height appropriate for the application. The front window must be kept clean and free of obstructions; a dirty window may reduce detection range. The scanner includes an integrated configuration memory for storing field parameters, allowing the device to be replaced without reconfiguration. Diagnostic data output via PROFIBUS or RS-422 allows remote monitoring of scanner status, including contamination warnings. The scanner is factory-calibrated and requires no routine calibration, though periodic functional testing (as required by safety regulations) should be performed. Cleaning of the front window should be done with a soft, lint-free cloth and mild detergent.

Environmental and Compliance

The S30A-6011EA is CE certified and meets EMC requirements for industrial environments. It is Type 3 compliant with IEC 61496-1/-2, SIL2 compliant with IEC 61508, and PL d / Category 3 compliant with EN ISO 13849-1. The scanner is IP65 rated for dust and water jet protection, making it suitable for indoor and outdoor industrial applications. Operating temperature range is -10°C to +50°C, with storage from -20°C to +70°C. Humidity tolerance is 10-90% non-condensing. The device is designed for use in pollution degree 2 environments and requires a protective housing for outdoor installations if direct weather exposure is expected. The scanner's optical components are protected by an anti-reflection and anti-fog coating, ensuring reliable operation in humid conditions. The device is RoHS compliant.
