The safety light curtain is primarily composed of two sections: the emitter and the receiver. The emitter releases infrared beams, which the receiver captures to create a light curtain. When an object penetrates this light curtain, the receiver promptly reacts through the internal control circuit, directing the equipment (such as a punch) to stop or trigger an alarm to protect the operator, thereby ensuring the equipment's normal and safe operation.

Multiple infrared transmitting tubes are placed at equal intervals on one side of the light curtain, with an equal number of infrared receiving tubes arranged in the same manner on the opposite side. Each transmitting tube aligns perfectly with a corresponding receiving tube in a straight line. When no obstacles exist between the transmitting and receiving tubes, the modulated light signal from the transmitter reaches the receiver effectively. Once the receiver captures this signal, the internal circuit outputs a low level. Conversely, if an obstruction is present, the modulated signal from the emitter does not reach the receiver as intended. Consequently, the receiver fails to obtain the modulated signal, resulting in the internal circuit outputting a high level. When no objects interfere with the light curtain, the modulated signals from all transmitting tubes reach their corresponding receiving tubes on the other side, causing all internal circuits to output low levels. This method allows the system to detect the presence or absence of an object by analyzing the status of the internal circuits.

1. Take into account the particular surroundings and duties of the operator. For machinery such as paper trimmers, where the operator frequently ventures into the perilous zone and maintains close proximity, accidents are more probable. Consequently, opt for narrower optical axis spacing (e.g., 10mm) when utilizing light screens to safeguard fingers.

2. Likewise, if the frequency of accessing hazardous areas is lower or the distance is greater, you may opt for light screens to shield the palm (spacing of 20-30mm).

3. To safeguard the arm in hazardous zones, opt for light screens with slightly wider spacing (40mm).

4. The utmost spacing is designated for safeguarding the entire body. Select light screens with the broadest spacing (80mm or 200mm).

This determination should be based on the specific machinery and equipment, with conclusions drawn from actual measurements. Take note of the distinction between the height of the safety light screen and its protective height. [Safety light screen height: the overall structural height of the light screen; Protective height: the effective safeguard range during operation, calculated as effective safeguard height = optical axis spacing * (total number of optical axes - 1).

The through-beam distance, or the gap between the transmitter and receiver, should be established according to the actual conditions of the machinery and equipment, facilitating the selection of a suitable light screen. Following the determination of the through-beam distance, consider the required cable length as well.

Ensure compatibility with the signal output method of the safety light screen. Some light screens may not align with the signals output by certain machinery, necessitating the utilization of a controller.

Select either an L-shaped bracket or a rotating base bracket based on your specific needs.
