Rockwell Automation 450L GuardShield POC Safety Light Curtains Alternatives & Competitors

The SFLA series safety light curtains are installed in potentially dangerous or hazardous areas to safeguard personnel from injury. The light curtains feature proven technology from Autonics area sensors and mapping sensors. The light curtains are built to meet internationally safety standards and regulations. Various detection models (finger/hand/hand-body detection) and safety functions are available for diverse applications. The dedicated software atLightCurtain allows real-time status monitoring user settings such as automatic muting/blanking area functions.

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 445L Guardshield™ POC Type 4 Micro 400 safety light curtains are economical three-box safety light curtains in a small housing. Designed for use in benign industrial environments (IP54), this light-duty system is targeted to the semi-conductor, micro electronic and small assembly machine markets. We also offer these light curtains in cascadable configurations and in IP69K enclosures. The Micro 400 requires a dedicated controller such as the MSR41 for ON/OFF applications or the MSR42 for advanced safety functionality.

Our 450L GuardShield™ PAC Safety Light Curtains help protect personnel from hazardous machinery. These light curtains are designed for whole-body detection and are typically positioned around an area or in front of a machine process entry or exit area that poses a moderate to high risk of operator injury. Our GuardShield 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. Like the other advanced products in the 450L GuardShield line, the PAC versions also feature integrated laser alignment, cascading, blanking, and integrated muting.

Features a compact design 30 mm x 30 mm (1.18 in. x 1.18 in.)
Includes Integrated Laser Alignment System (ILAS), plug-in DIP switches and integrated muting option available for easy installation and configuration
Offers innovative plug-in modules (available separately) which enable basic (ON/OFF)
Provides cascading plug-ins for serial connection of safety light curtains
Covers a wide range of protection heights 150 mm, 600 mm, 900 mm or 1050 mm and available in 1-, 2-, 3-, or 4-beam models respectively
Offers a versatile mounting options for enhanced application flexibility

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.

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.
