No Blind Spot Safety Light Curtain(30*15mm)

● DQB series ultra-thin light output section is only 15mm

● Small size, easy to install

● Ultra-fast response speed (less than 15ms)

● Can effectively shield 99% of interference signals


It is widely used in large machinery such as presses, hydraulic presses, hydraulic presses, shears, automatic doors, or dangerous occasions that require long-distance protection.

    Features of the Product

    ★ Excellent self-check function: Make sure the regulated electrical appliances don't receive the incorrect signal in the event that the safety screen protector fails. 
    ★The system exhibits strong anti-interference ability against electromagnetic signals, stroboscopic light, welding arcs, and surrounding light sources. 
    ★Its easy installation and debugging, straightforward wiring, and attractive appearance are further highlights.  
    ★Its superior seismic performance is attributed to the use of surface mounting technology. It complies with TUV CE certification and standard safety grade lEC61496-1/2. 
    ★The performance in terms of safety and dependability is strong, and the corresponding time is low (< 15 ms). 
    ★The design dimensions are 30 mm by 30 mm. 
    ★ The air socket allows the safety sensor to be attached to the cable (M12). 
    ★Every electronic component uses accessories from well-known brands.

    Contents of the Product

    The emitter and the receiver are the two basic components of the safety light curtain. Infrared rays are released by the transmitter, and the receiver absorbs them to create a light curtain. The light receiver reacts instantly through the internal control circuit when an object enters the light curtain, stopping or alarming the apparatus (like a punch) to safeguard the operator. safety and guarantee the equipment's regular, secure operation.
    On one side of the light curtain, there are several infrared transmitting tubes spaced equally apart, and on the opposite side, there are an equal number of infrared reception tubes placed similarly. Every infrared transmission tube is placed in a straight line with a matching infrared receiving tube. The modulated signal, or light signal, emitted by the infrared transmitting tube can effectively reach the infrared receiving tube when there are no obstructions in the path of the tubes on the same straight line. Following the modulated signal's receipt by the infrared receiving tube, The matching internal circuit produces a low level as an output. The modulated signal, or light signal, sent by the infrared transmitting tube, however, cannot easily pass to the infrared receiving tube when obstructions are present. The infrared receiving tube is currently Since the tube is unable to receive the modulation signal, the internal circuit output that results is high level. All internal circuits output low level when no item passes through the light curtain since all infrared transmitting tubes' modulated signals, or light signals, can successfully reach the appropriate infrared receiving tube on the opposite side. In this manner, the internal circuit state can be examined to determine if an object is present or absent.

    How to Choose a Safety Light Curtain

    Step 1: Find the optical axis spacing (resolution) of the safety light curtain.
    1. It is vital to examine the operator's individual surroundings and operations. If the machine equipment is a paper cutter, the operator approaches the risky area more frequently and is closer to it, making accidents more likely, hence the optical axis spacing should be minimal. Light curtain (e.g. 10mm). Consider using light curtains to shield your fingers. 
    2. Similarly, if the frequency of approaching the risky region decreases or the distance increases, you can opt to safeguard the palm (20-30mm). 3. If the dangerous area must shield the arm, use a light curtain with a little longer distance (40mm). 
    4. The light curtain's maximum limit is designed to safeguard the human body. You can select the light curtain with the longest distance (80mm or 200mm). 
    Step 2: Select the protection height of the light curtain. 
    It should be determined using the appropriate machine and equipment, and conclusions can be formed from actual measurements. Pay attention to the difference between the safety light curtain's height and its protective height. [The height of the safety light curtain: the total height of the safety light curtain's appearance; the protection height of the safety light curtain: the effective protection range when the light curtain is in use, that is, the effective protection height = optical axis spacing * (total number of optical axes - 1)] 
    Step 3: Choose the light curtain's anti-reflection distance.
    The through-beam distance refers to the distance between the transmitter and receiver. It should be determined based on the real scenario of the machine and equipment, allowing a more appropriate light curtain to be chosen. After estimating the firing distance, consider the length of the cable. 
    Step 4: Identify the output type of the light curtain signal. 
    It must be determined using the signal output mechanism of the safety light curtain. Some light curtains may not match the signals generated by the machine equipment, necessitating the usage of a controller. 
    Step 5: Bracket Selection 
    Depending on your demands, you can choose an L-shaped bracket or a base rotating bracket.
