Conventional light curtains had dead zone where there are no beam axis at both ends. With SE4D the first beam axis placed right along the edges, detection can be performed along the entire area. Up to 3 sets (emitter/receiver) can be connected in series to cover L or U shaped configurations, or to guard both the front and back of a machine.
SE4D light curtain is equipped with a muting control function that causes a line to stop only when a person passes through the light curtain, but does not stop the line when an object passes through. The muting sensor and muting lamp can be directly connected to the light curtain. A special controller for muting is not required thus reducing cost.
Fixed blanking prevents the control output (OSSD1/2) from turning off when a specific beam is interrupted. This is used in applications where a specific beam is always interrupted. When the object is moved outside of the sensing area, the control output (OSSD1/2) turns off. Floating blanking function prevents the control output (OSSD1/2) from turning off when the number of beams interrupted is less than a preset number. The number that can be set is from 1 to 3 beams. This function enables sensing even when the position of the obstacles changes in the sensing area.

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.

The sensors provide reliable detection even in areas with high ambient lighting, up to 100,000 lux. The series also features various user-friendly functions including installation mode function, mutual interference prevention function, and self-diagnosis functions.
Sick Mirror columns with protective field height mirror
No reviews yet.
Mirror columns from SICK are used in areas in which multi-sided protection of hazardous points, such as machining centers, is required. The right solution is to combine multiple light beam safety devices or safety light curtains with mirror columns to deflect the light beam. Several sides of a machine can be protected with just one pair of sensors, which reduces wiring effort significantly. It is easy to adjust the deflector mirrors, which are mounted in stable columns. Unimpeded access for feeding operations and tool and program changes is another advantage compared to a mechanical fence and results in higher productivity.

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.
