- Detection accuracy
- Optical axis spacing
- Light curtain form
The light curtain in the light curtain safety device plays the role of protecting the safety of the equipment. When foreign objects enter the laser safety light curtain protection net, when light is blocked by the object, long distance protection Highly safe light curtain device safety light The barrier reacts immediately through the internal control circuit, that is, outputs a signal in the output part for emergency braking of machine tools such as punches and presses.
What are the characteristics of this safety light curtain?
1. Light curtain optical axis spacing: also called resolution, choose ir light curtain with optical axis spacing of 10mm, 20mm, 30mm, 40mm, 80mm, which can protect the smallest detection objects (protect fingers, palms, arms, etc.) Safety)
2. Signal output of muting sensor: Choose the appropriate output method according to the actual application scenario.
3. Self-checking function of laser curtain sensor: when the light curtain sensor loses power or fails itself, make sure not to send an error signal to the controlled device control.
4. Anti-interference ability: Good anti-interference ability against electromagnetic signals, strobe lights, welding arcs and surrounding light sources.

For the press where the slider cannot be braked to stop at any position of the stroke, the top dead center protection can only be achieved during a single operation, that is, after the previous stroke ends, the next stroke has not started yet, if the safety light curtain sensor is in a shading state , The next trip cannot be started (sufficient safety distance must be guaranteed).
