Product composition

The security light screen primarily comprises of two components, specifically the emitter and the recipient. The transmitter emits infrared beams, which are captured by the receiver to create a light screen. Whenever an item enters the light screen, the recipient instantly reacts via the internal control circuit and manages the machinery (e.g., a press) to halt or alert for safeguarding the operator's well-being and ensuring the regular and secure functionality of the machinery.

Multiple infrared transmitting tubes are positioned at uniform intervals on one edge of the light screen, with an equivalent number of infrared receiving tubes arranged in a corresponding pattern on the opposite side. Each infrared transmitting tube has a matching infrared receiving tube and is placed on the identical straight line. . In instances where there are no obstructions between the infrared transmitting tube and the infrared receiving tube on the same straight line, the modulated signal (light signal) sent out by the infrared transmitting tube can successfully reach the infrared receiving tube. Subsequent to receiving the modulated signal, the corresponding internal circuit generates a low level. Conversely, if there are obstacles, the modulated signal (light signal) from the infrared transmitting tube encounters difficulty reaching the infrared receiving tube. Consequently, the infrared receiving tube fails to receive the modulated signal, resulting in the corresponding internal circuit outputting a high level. When no object traverses the light screen, all infrared transmitting tubes emit modulated signals (light signals) that successfully reach the corresponding infrared receiving tube on the opposite side, causing all internal circuits to output a low level. Consequently, by examining the internal circuit status, information regarding the presence or absence of an object can be ascertained.

Safety Light Curtain Selection Guide

Step 1: Ascertain the spacing of the optical axis (resolution) for the safeguard light screen

1. Deliberation should encompass the specific operator environment and actions. If the machinery involved is a paper cutter, with operators frequently accessing perilous zones in close proximity, accidents are more likely to occur, hence a smaller optical axis spacing is warranted for the light screen (e.g., 10mm). Factor in light screens for finger protection.

2. Similarly, if the frequency of perilous zone access is lower or the distance is greater, palm protection (20-30mm) can suffice.

3. When safeguarding the arm in perilous zones, opt for a light screen with a slightly larger spacing (40mm).

4. The utmost limit of the light screen is human body protection. Opt for the light screen with the widest spacing (80mm or 200mm).

Step 2: Elect the protection height for the light screen

Determine this based on the specific machinery and equipment, drawing conclusions from actual measurements. Note the disparity between the light screen's total height and its protection height. [The light screen's height: the overall appearance height; the protection height: the effective safeguard range during operation, i.e., effective protection height = optical axis spacing * (total number of optical axes - 1)]

Step 3: Choose the anti-glare distance for the light screen

The through-beam distance denotes the gap between transmitter and receiver. Tailor this to the machinery and equipment's actual conditions for optimal light screen selection. Following distance determination, consider cable length as well.

Step 4: Establish the signal output type for the light screen

This should align with the safety light screen's signal output method. Certain light screens may not synchronize with machinery equipment signals, necessitating controller usage.

Step 5: Bracket preference

Select either L-shaped or rotating base brackets as per requirements.
