The transmitter generates infra-red light beams flashing at high speed in synchronous action. The parallel light beams with a spacing of 7,5mm or 14,3mm are monitored by miocro-controllers. The receiver evaluated the arriving beams in synchronous action to the transmitter.

Due to the closeness of the beams, a resolution of 14 mm / 30 mm is achieved. If an obstacle is placed into the protective field, i.e. at least iner lieght beam is interrupted, the hazardous movement of the machine is stopped, i.e. a new start is not possible.

BANNER Type 4 safety light curtain EZ-SCREEN LS SERIES
Scanning range 12m

5/5 (1)

BANNER's EZ-SCREEN LS light curtains are a reliable and easy-to-use safety device designed for machine safeguarding in challenging manufacturing and packaging environments. With three resolutions available, ranging from 14 mm to 40 mm, and a range of up to 12 m, these light curtains provide end-to-end sensing with no blind zones. The aluminum housing and metal end caps protect each emitter and receiver against impacts, while highly visible alignment indicators and intuitive diagnostics make setup and troubleshooting a breeze.The EZ-SCREEN LS system requires no PC software or DIP switches for quick and easy configuration. The dual scan technology ensures high immunity to EMI, RFI, ambient light, weld flash, and strobe light. The no blind zone design eliminates gaps in detection, while the system can cascade up to four systems of any length, resolution, and number of beams.These light curtains are certified to Type 4 per IEC 61946, Category 4 PLe per EN ISO13849.1, and SIL3/SILCL3 per IEC 61508/IEC 62061, exceeding OSHA/ANSI control reliability requirements. The EZ-SCREEN LS pair model numbers come with an LS receiver, LS emitter, end-cap bracket kit, and center-mount bracket kit, making them a reliable choice for a range of manufacturing and packaging applications.

Our Bulletin 450L GuardShield™ POC safety light curtains are unlike traditional safety light curtains, which are based on separate transmitter and receiver units. Patented technology allows each transceiver to be used as a transmitter or receiver via an innovative plug-in module. The 450L-B is the basic model with on/off functionality. The advanced 450L-E model features integrated laser alignment, cascading, and integrated muting. Connection over EtherNet/IP makes the 450L-E light curtain a smart safety device that enhances safety while providing connectivity through The Connected Enterprise®Includes patented technology that allows each transceiver to be used either as a transmitter or receiver via an innovative plug-in moduleFeatures an active protective field that senses over the entire length of a transceiverOffers a wide range of protection heights 150…1950 mm (5.9…76.7 in.) in increments of 150 mm (0.5 ft)Features a compact housing design 30 x 30 mm (1.18 x 1.18 in.)Provides easy configuration of the start mode, external device monitoring (EDM), and scanning range by DIP switches on the plug-in modulesProvides basic on/off functionality (450L-B only)Bulletin 450L-E Safety Light CurtainsOffers enhanced features including integrated laser alignment, longer operating range and options for cascading, blanking and integrated mutingFeatures integrated laser alignment for fast and reliable installationOffers built-in cascading and integrated muting capabilities Typical applications for the Bulletin 450L-B Safety Light Curtains include:Electronic fencesForming operationsRobot cellsPressesWorkstations
Fiessler Type 4 safety light curtain ULVT
No reviews yet.
The safety light curtains ULVT consist of the two components: transmitter and receiver. The distance between both components and the overall height result in those protection width and - height. By the modular construction protection heights of 100mm to 1900mm are realizable. Special sizes are also available. If an object is in the protection field, i.e. it is darkened at least one of the beams, the two outputs of the receiver interrupt the dangerous movement of the machine, or prevent a start. A renewed start of the machine is in the operating mode with restart only possible by pressing the start push-button during a free protection field. Several LED at the receiver display thereby the respective operating condition. The system detects an internal or external error the machine is immediately switched off and the LED in the transmitter or in the receiver shows by flashing the error status.
Fiessler Type 2 safety light curtain TLVT series

The safety light curtains TLVT consist of the two components: transmitter and receiver. The distance between both components and the overall height result in those protection width and - height. By the modular construction protection heights of 100mm to 1900mm are realizable. Special sizes are also available. Transmitter and receivers operate synchronously, i.e. at the same point in time only a light beam and a reception item are active. The synchronisation is made by the first light beam and the first reception item. Between transmitter and receivers therefore no electrical connection is necessary. The transmitter creates infrared light beams, which are switched on and off rapidly successively. The parallel light beams with a distance from 7,5mm are controlled by two a chip micro controllers. A resolution of 14mm is realised by the beam distance. Synchronously to the light beams of the transmitter in the receiver all reception items are analysed by two a chip micro controllers. If an object is in the protection field, i.e. it is darkened at least one of the beams, the two outputs of the receiver interrupt the dangerous movement of the machine, or prevent a start. A renewed start of the machine is in the operating mode with restart only possible by pressing the start push-button during a free protection field. Several LED at the receiver display thereby the respective operating condition. The system detects an internal or external error the machine is immediately switched off and the LED in the transmitter or in the receiver shows by flashing the error status.

Access Srl Multibeam light curtain
No reviews yet.
Photocell barriers include a number of different infrared rays aligned along both a transmitter and a receiver bar. It is enough that one of the infrared streams is interrupted to detect an infiltration in the dangerous working area which leads to an immediate close-off of the output safety contactors connected to the machinery emergency stop. The safety photocell barriers form a barrier of parallel infrared streams which are activated one after the other according to a multiplex process and a high scanning speed. A specific stream acts as a synchroniser. The standard height of the guard depends on the number of infrared streams and the distance of the lenses. Immaterial barrier resolutions allow to detect fingers, hands, limbs or approaching bodies. Resolutions are defined according to the type of machinery which needs guarding, the working area and the level of safety required. Access' immaterial barriers are integrated to the guard fencing systems and are selected among the best components available on the market for that particular application and safety level requirement according to UNI EN 62061 standards.
