The muting arm set is designed for sequential muting with four parallel retro-reflective sensors. This configuration provides multiple sensing stages for detecting suitable material as it passes through a protected area.
The retro-reflective sensing principle uses an optical beam directed toward a reflector. When the beam is interrupted by the transported object, the sensor changes its output state according to its dark-on configuration.
The less-than-2.5 m monitoring range provides flexibility for suitable machine entrances, conveyor systems and material-transfer points.
The IP65 protection rating supports use in suitable industrial environments where protection against dust and water jets is required within the specified operating conditions. The -30 °C to +55 °C temperature range provides additional flexibility for factory and machine installations.
The four-sensor arrangement provides sequential muting with four parallel retro-reflective sensors.
The sensing stages are positioned to monitor the movement of suitable goods through the safeguarded area. Sequential detection allows the compatible safety system to recognize the intended material-transfer sequence.
Correct installation, sensor alignment and muting configuration are essential for the safe operation of the complete machine-safety system.
The set is specifically intended for compatible safety light grids with muting functionality. It can be mounted directly on the safety light grid, providing a practical installation arrangement for suitable machine-safety applications.
The four sensing stages can support controlled material transfer through safeguarded machine entrances, conveyor passages and other suitable protected areas.
The complete safety installation should be designed and validated according to the manufacturer's instructions and applicable machine-safety requirements.
The muting arm set is suitable for applications where goods or materials need to pass through a safeguarded area without unnecessarily interrupting the safety protection function.
Typical applications include conveyor systems, automated production lines, machine loading and unloading points, pallet handling systems and material-transfer stations.
The four retro-reflective sensing stages can be integrated into suitable conveyor applications where materials need to pass through a protected machine area.
The sequential arrangement can help identify the intended movement of transported goods and provide the required sensing signals to compatible safety-control equipment.
The set can be used at suitable machine loading and unloading points where materials need to enter or leave a safeguarded area.
