Muting works by allowing objects to pass through operational light curtains by temporarily suspending their safety function, then resuming after the object has passed through the light curtain’s beams. Adding mute arm kits to the S4B helps create a muting solution that simplifies system design and installation. Available for one-sided, X-, and T- configurations, the rigid mute arms protect sensors from damage and misalignment. Flexible mounting options for photoelectric sensors accommodate a wide range of object sizes passing through. The muting block consolidates wiring by combining the S4B light curtains and non-safety sensors into one block.

With the turn of a key, Remote Fixed Blanking allows users to quickly configure portions of the S4B light curtain’s sensing field to ignore fixed objects such as brackets, tooling, or part supports—enabling fast teaching or re-teaching to adapt to changes in fixture configuration or layout, without accessing concealed DIP switches or cycling power, while a built-in ±1 beam tolerance within the blanked area prevents false triggers in high-vibration environments. When changes have to happen, this keeps them short, simple, and controlled—so the line can recover fast. If a defined object is moved or removed, the system halts operation to maintain safety—and with another quick key turn, coverage is updated.
