Garantta's measurement light curtain consists of a transmitter and a receiver. The transmitter's infrared light shines directly onto the receiver, forming a light curtain system. A target object placed between the transmitter and receiver will block some of the light, preventing it from reaching the corresponding receiving device.
Garantta's Counting Measuring Light Curtain synchronous scanning to identify blocked channels. First, one transmitter emits a light pulse from one channel, and the corresponding receiver simultaneously searches for that pulse. Once found, the scan of that channel is complete, and the process continues to the next channel until all scans are completed. After one scan cycle, the system records which channels are illuminated and which are blocked, thereby calculating the product's dimensions.
features

Advantages
- Self-Test Function:
Upon powering on, the system performs a self-test within 2 seconds to ensure there are no faults.
- Power-On Delay Function:
The light curtain activates only after a 3-second delay, providing operators and equipment with a buffer period to enhance safety.
- Blind Zone Filtering Function:
When objects pass through the Counting Measuring Light Curtain slowly, the system maintains a stable disconnection signal, preventing accidental machine activation and ensuring safer, more reliable production.
- Optical Synchronization Technology:
The light curtain uses advanced optical synchronization technology instead of traditional data line synchronization, eliminating signal interference and the need for long data line connections.
- Comprehensive Self-Diagnostic Function:
Designed with the latest industrial safety technology, the system ensures no incorrect signals are sent to the control unit in the event of a power loss or internal failure.
- Long-Life Dual Relay Output Control:
The controller features high-reliability dual relays with an electrical lifespan of over 2 million cycles. Once the relay reaches its lifespan, it can be easily replaced.
- Self-Protection Function:
When the light curtain is blocked, it remains in a disconnected state. It only returns to the light-transmitting state after the reset button is pressed.
- Signal Output:
By default, the relay output is normally closed when the light is on and normally open when the light is blocked (factory setting).
- Dual Independent OSSD Output:
For enhanced safety, the system uses dual independent redundant outputs, enabling automatic fault prevention and compatibility with safety relays and safety PLCs.
- Superior Anti-Interference Capability:
With infrared communication and a specialized optical system, the light curtain offers strong resistance to electromagnetic signals, strobe lights, welding arcs, and ambient light sources.
- Faster Response Time:
The Counting Measuring Light Curtain has a response time of less than 10ms.
- Overload and Short-Circuit Protection:
In the event of an overload or short circuit, the system enters a protective state and shuts down the light curtain safety system.
FAQ
Q: What about the application of counting measuring light curtains in the spray coating industry?
A: In the process of automobile production, it is necessary to spray paint the appearance of the car. At this time, a measuring spray light curtain is used. The measuring light curtain measures the external dimensions and shape of the object through scanning; that is, the external dimensions of the object are formed based on the number of light blocks, and then the obtained data is transmitted to the spray control system. The spray control system is set by software and outputs a signal to the spray robot for painting the shape of the workpiece. After a workpiece is sprayed, the system will give the next control signal to spray the next workpiece.
Q: What about the purpose of the Counting Measuring Light Curtain?
A: 1. Measure the bar diameter and the tire inner and outer diameters.
2. Measurement of strip width for plates, steel strips, etc.
3. The measurement of length, width, height, etc., inside the box and bag can calculate the volume.
4. Measuring and distinguishing the height of products entering the three-dimensional warehouse,
5. Spray contour detection, positioning the spray gun.
6. Detect objects larger than 1mm for detecting their presence or counting.
