Varying width light curtains

The F3SN-A/B safety light curtains and F3SH-A multi-beam sensors are designed to prevent human contact with dangerous moving parts by detecting fingers, hands and bodies in dangerous areas.

The sensor, with a surface area of 30 x 30 mm, has a detection capability of 14 and 25 mm resolution for finger and hand detection, protective height of 217 to 1822 mm for the light curtains, standard four beam with 300 mm beam spacing for perimeter guarding applications, both of which have an operating range of up to 10 m. The sensors deliver fast response times of 15.5 ms maximum.

The F3SN-A/B has narrow beam spacing for point-of-operation guarding, while the F3SH-A has wide beam spacing for body protection in perimeter guarding.

Users can connect up to three sets of the safety light curtains in series, preventing manual interference and permitting the highest level of safety design. Both the F3SN-A and F3SH-A conform to the now-mandatory global safety standards for safety sensors, being type 4 sensors meeting the highest safety standards of category 4, while the F3SN-B conforms to category 2.

The sensors' self-powered setting console provides all function settings, including floating and fixed blanking. Functions such as monitoring and copying to multiple sensors can be set easily and safely. Password protection prevents inadvertent changes to the settings.

The safety sensor units also incorporate a variety of safety functions to make them suitable for all kinds of safety circuit systems. An indicator bar facilitates easy beam alignment and reliable installation. Double-ended connector cabling for both the safety sensor and the safety controller makes the system easy to install.
