Product composition
The safety light screen mainly comprises of two components, specifically the transmitter and the receiver. The emitter emits infrared beams, which are captured by the receiver to establish a light barrier. Upon an object's entry into the light barrier, the receiver promptly reacts via the internal control circuit, directing the equipment (like a punch machine) to halt or trigger an alarm, ensuring operator safety and maintaining the equipment's normal and secure operation.
At one edge of the light panel, numerous infrared emission tubes are evenly positioned, while an equal count of infrared reception tubes are arranged similarly on the opposing edge. Each infrared emitter aligns precisely with a corresponding infrared detector and is placed along the same linear path. When unobstructed, the modulated signal (light transmission) emitted by the infrared emitter successfully reaches the infrared detector. Upon receipt of the modulated signal, the respective internal circuit emits a low level. However, when obstacles are present, the modulated signal emitted by the infrared emitter encounters hindrances in smoothly reaching the infrared detector. Consequently, the infrared detector fails to capture the modulated signal, resulting in the corresponding internal circuit emitting a high level. In situations where no objects intersect the light panel, the modulated signals emitted by all infrared emission tubes reach their corresponding infrared reception tubes on the opposite side, causing all internal circuits to emit low levels. This method facilitates the determination of object presence or absence by analyzing the internal circuit's condition.
Safety Light Curtain Selection Guide
Step 1: Establish the optical axis spacing (resolution) for the safety light screen
1. Take into account the specific environment and the operator's activities. For instance, if the machine involved is a paper cutter and operators frequently access hazardous areas, accidents are more likely. Therefore, opt for a smaller optical axis spacing for the light screen (e.g., 10mm) to safeguard fingers.
2. Similarly, if access to hazardous areas is less frequent or the distance is greater, consider palm protection (20-30mm).
3. For areas requiring arm protection, select a light screen with a slightly larger spacing (around 40mm).
4. The ultimate goal of the light screen is to protect the human body. Choose the widest spacing available (80mm or 200mm).
Step 2: Determine the protective height of the light screen
The determination ought to rely on the particular machinery and apparatus, with inferences derived from tangible measurements. Mind the difference amid the comprehensive altitude and the shielding altitude of the light panel. The comprehensive altitude pertains to the complete outlook, whereas the shielding altitude signifies the operational safety zone, computed as: operational safety height = optical axis interval * (total quantity of optical axes - 1).
Step 3: Choose the light screen's anti-reflection distance
The through-beam distance, measured between the transmitter and receiver, should be tailored to the machine's setup for selecting an appropriate light screen. Additionally, consider the cable length after determining the shooting distance.
Step 4: Specify the output format of the light screen signal
This should align with the signal output method of the safety light screen. Some light screens may not sync with the machine equipment's signals, necessitating the use of a controller.
Step 5: Bracket selection
Select either an L-shaped bracket or a rotating base bracket based on your requirements.
