The muting function of the light curtain sensor(safety light grids) is a safety measure that allows for temporary shielding of the light curtain when necessary to ensure the continuity of the production process.

 The light curtain sensor generates a protective light curtain by emitting infrared radiation. When the light curtain is obstructed, the device will emit a shading signal to control potentially dangerous mechanical equipment to stop working, thereby avoiding safety accidents. However, in practical applications, especially in places where materials frequently enter and exit, the muting function is introduced to ensure personnel safety and improve production efficiency. This function allows for temporary shielding of the light curtain under specific conditions, allowing mechanical equipment to continue operating without affecting production. The duration of the shielding function should not be too long, usually set as the maximum time required for the workpiece to pass through the light curtain to ensure a balance between safety and efficiency.

 The implementation of muting function includes several key aspects:

Muting function: allows temporary blocking of light curtains to avoid interrupting production operations while ensuring personnel safety. ‌

Time monitoring: Ensure that the duration of shielding is not too long, usually set as the maximum time required for the workpiece to pass through the light curtain.

Synchronization restriction: The synchronization time between paired shielded sensors is relatively short to improve the reliability of shielding.

Fault handling: In the event of a malfunction, the workpiece can be manually removed from the light curtain protection area.

 In addition, according to different working conditions and material characteristics, the shielding of safety light curtains can have multiple working modes to meet the needs of various production environments.

 Tianjin G-TEK Sensor LDA series light curtains have muting function, product with type 4 (SIL3)safety design, a minimum protection height of 160mm, a maximum protection height of 1920mm, and optional beam spacing of 10mm, 20mm, 40mm and 80mm. Excellent resistance to ambient light to 10000 Lux. For more details, please feel free to consult us. When paired with the LDA series, it is recommended to use the PF21 series photoelectric sensor from Tianjin G-TEK Sensor. The product is miniature design and has superior performance.There are options for retro-reflective sensor and through-beam sensor depending on the detection distance. The sensing distance for example 1.5m (retro-reflective type), 5m, 10m, 15m, 30m (through-beam type).

In summary, the muting function of the light curtain sensor is an important safety measure that can improve production efficiency by temporarily shielding the light curtain while ensuring production safety. It is one of the indispensable safety technologies in industrial production
