Safety Light Curtain

• Used to safeguard operators on packaging lines, particularly with sealing machines, form-fill-seal equipment, and bagging systems.
• Commonly integrated into automated assembly lines where human interaction with moving parts carries a risk.
• Applied in material handling systems, such as palletisers and conveyors, to prevent access to hazardous zones.
• Utilised in robotic work cells to create a protective barrier around the robot's operational envelope.
• Found in various industrial machinery requiring point-of-operation safeguarding, like presses or cutting equipment.

Sensing range

Typically between 0.1m and 15m, depending on the model and application.

Resolution (object detection capability)

Commonly 14mm or 30mm for finger or hand protection, respectively.

Protective field height

Typically ranges from 300mm to 2000mm, selected based on the safeguarded area.

Response time

For this class of equipment, typically less than 20ms to ensure rapid machine shutdown.

Safety integrity level (SIL) / Performance level (PL)

Commonly rated up to SIL 3 or PL e, indicating high reliability for safety functions.

Power supply

Typically 24V DC, supplied by the machine's control system or a dedicated power unit.

Output type

Units of this type commonly feature OSSD (Output Signal Switching Device) outputs for direct connection to a safety relay or PLC.

• What is a safety light curtain and how does it work?

  A safety light curtain creates an invisible protective field using an array of infrared light beams. If an object or person breaks any of these beams, the curtain sends a stop signal to the machine, preventing hazardous operation.

• Why is a safety light curtain important for packaging machinery?

• Can this light curtain be integrated with existing machinery?

• What does the 'trailing edge signal' option mean for production?

• What maintenance is typically required for a safety light curtain?

Centrifuge rotors, buckets and accessories hold strong reputations for reliability and durability when purchased used. Buyers typically value compatibility verification with specific centrifuge models before purchase, as mismatched components compromise performance and safety. Industry users commonly praise the robustness of quality rotor materials and balanced construction. When sourcing used examples, inspecting for corrosion, wear patterns and proper calibration certification proves essential. Established manufacturers' products tend to command buyer confidence due to consistent build standards and longer operational lifespans across demanding laboratory and pharmaceutical applications.
