Fiessler Type 4 safety light curtain ULVT 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.

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.

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.

The SFL 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.

Safety light curtains with integrated Muting functions. The Janus series is the solution for the protection of a vast number of high-risk industrial applications, in particular those requiring a high level of integration of the safety functions. For example, in the models with built-in Muting function, Janus guarantees the independence of the light curtain from the control circuits of the system (often distant from the protected gate) and, where necessary, also the integration of the Muting sensors. Settings of each function integrally performed via themain connector.

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.

TLCT/ILCT safety light curtains each comprise two components:

Light transmitter and light receiver.

The clearance between these two components and the installation height determine the width and height of the protective field (Figure 5/1). Modular design permits realization of protective field heights ranging from 100 mm to 1500 mm in 100-mm steps.

The transmitter generates infrared light beams in rapid pulses. These parallel light beams are analyzed by two single-chip controllers in the transmitter.

The beam spacing determines the resolution. If an object enters the protective field, i.e. if at least one light beam is interrupted, the receiver's two outputs stop the machine or prevent it from starting, thus avoiding hazards.

In the restart with interlock operating mode, the machine can only be restarted by means of the start button once the protective field has been cleared again.
