S4B Series Heavy-Duty Type 4 Safety Light Curtain
Banner Engineering's S4B Series offers robust and reliable safety for industrial machinery, ensuring operator protection through advanced light curtain technology.
Product Overview
The S4B Heavy-Duty Type 4 Safety Light Curtain is designed for demanding industrial environments. It provides a critical safety barrier, preventing access to hazardous machine areas when the light beam is interrupted. Key benefits include quick and easy installation, reduced downtime through intuitive diagnostics, and simplified maintenance with a removable connection system.
The system features a visible red light beam array, acting as a protective screen. When an object, such as a hand or body part, breaks the beam, the safety output is immediately deactivated, stopping the machine.
Key Features and Benefits
Simple Installation
The S4B is engineered for straightforward installation, operation, and troubleshooting. It utilizes LED alignment indicators and specialized brackets to facilitate a quick setup. The system supports intuitive setup and swap-out, allowing users to select and save scan code settings without the need for a PC, which is crucial for easy replacement of units.
Alignment Zone Indicators
- ? Misaligned: Indicates a loss of signal due to a blocked beam or significant misalignment.
- ? Weak: Signals a weak signal due to slight misalignment or a dirty lens, alerting operators to potential issues before they cause downtime.
- ✅ Aligned: Confirms a strong signal, proper alignment, and no obstructions.
Rotating and locking brackets are included for flexible mounting.
Prevent Downtime
The S4B proactively helps prevent unexpected downtime. The weak beam strength indication (yellow light ?) and the corresponding output signal sent via pin 5 to a PLC or HMI alert operators to perform preventive maintenance, such as cleaning the lenses, before a complete system failure occurs.
Reliable Hand Detection
With a resolution of 30 millimeters, the S4B series ensures reliable detection of hands, providing a high level of safety against common industrial hazards.
Eliminate Costly Repairs
The integrated removable cordset with a 5-pin M12 QD connector allows for cost-effective replacement of only the damaged component, rather than the entire light curtain unit, significantly reducing repair costs and downtime.
Durability and Protection
- The protective window is recessed 4 mm for added durability against impacts.
- Features an end-to-end sensing design, meaning there is no blind zone, providing complete coverage.
