Yes. Thanks to the surface detection, a light curtain detects conveyed goods of different shapes and sizes over a defined detection range. This is particularly advantageous when changing products are transported on a conveyor belt and selective object detection with individual sensors is not sufficient.
A single sensor only detects objects at a specific point. A light curtain, on the other hand, monitors a wide detection range and thus also reliably detects objects of different heights, shapes or positions. For this reason, no separate sensors or complex mechanical adjustments are required for changing product variants.
Yes. A light curtain detects which light beams are interrupted by an object. This allows you to see if and to what height a product protrudes into the detection range. This allows products of different heights and dimensions to be reliably monitored on a conveyor belt.
Yes. Thanks to the surface detection, a light curtain detects products even if they are not always in the same position on the conveyor. The detection range can be designed to suit the application, so that varying object positions can also be covered.
Yes. Light curtains are suitable for many applications where objects cross or protrude into a defined detection range. These include, for example, presence, throughput, height, completeness and rejection checks.
Light curtains are particularly suitable for applications where objects need to be reliably detected or monitored over a larger detection range. Typical applications are:
- Detection of objects on conveyor belts
- Presence and throughput checks
- Height and completeness checks
- Ejection and accumulation checks
- Detection of products in chutes and transfer points
- Monitoring of infeeds, ejections and material flows
Emitters and receivers are positioned opposite each other in through-beam mode. An object is detected as soon as it interrupts one or more light beams between the two components. In reflex mode operation, the emitted light is reflected back from the object to the light curtain. This allows one-sided installation without an opposing receiver.
Reflex mode operation is particularly suitable for applications where emitter and receiver cannot be mounted opposite each other due to space or design reasons. As the light is reflected back from the object to the light curtain, one-sided installation is possible.
Pick-to-Light is a light-guided picking process. Light signals indicate to the operating personnel which storage compartment a part is to be removed from or which compartment it is to be placed into. This makes it possible to clearly assign storage locations, speed up work processes and reduce picking errors.
A light curtain pick-to-light functions in accordance with the retro-reflex principle. The emitted light is reflected back to the light curtain by a reflector integrated on the rear of the housing. If a person reaches into the compartment and interrupts a light beam, the sensor detects the removal and confirms it with a visual signal.
Light curtains pick-to-light provide quick visual feedback directly at the removal compartment. In this way, they support intuitive operation and help to reduce mistakes. Thanks to their compact format, they can be integrated into existing storage and picking stations to save space. Since the reflector is already integrated in the housing, no additional external reflector is required.
Yes. Thanks to its compact format, the light curtain can be mounted directly on the respective compartment. This means that the visual feedback takes place exactly where it is needed and immediately perceived during order picking.
wenglor light curtains pick-to-light are suitable for applications where parts must be removed from defined storage locations quickly, reliably and as error-free as possible. Typical areas of application are order picking, material provision and the supply of assembly workstations.
