    SZH series basic safety light curtains are widely used in various safety applications

    For extremely limited space: continuous protection zone
    The SZH series of waterproof and safety light curtains form a high-resolution continuous protection area covering the entire housing up to the end of the housing, minimizing the safety distance required for machine integration. In addition, the SZH series waterproof and safety light curtains can be protected up to 3m in height. As a result, the product allows distances above and below the safe area to be much smaller than existing safety standards. The SZH series waterproof safety light curtain also shortens the safety distance between the operator and the danger point, effectively improving production efficiency.
    Sturdy casing: SZH series waterproof and safety light curtain adopts high-strength aluminum profile as the outer casing to ensure the safety light curtain is resistant to bending and impact.
    Power-on: No security is required without any setup, and work and troubleshooting are fast.

    Quick commissioning with LED indicators: The SZH series of waterproof and safety light curtains can be used to perform all basic functions without pre-configuration and without the need for software. In addition, some models are equipped with integrated LED indicators and diagnostics, which effectively reduces commissioning time.
    Plug-and-play maintenance and replacement: SZH series waterproof safety light curtains can be quickly maintained without configuration or wiring. All products feature an exquisite bracket design and standardized M12-4 pin plug technology, simplifying the replacement process for each device. In addition, bright LEDs continuously provide status information for all processes.
    The SZH series of waterproof and safety light curtains are designed with a sturdy and clean shape to ensure that the product meets the functional requirements. The SZH series waterproof safety light curtain is specially designed for operation protection applications. It can be started immediately after power-on, without a lot of configuration work, and its detection range can be precisely adjusted according to the application needs. In addition, the safety light curtain has the following features:
    • Integrated alignment LEDs for fast and accurate positioning of the transmitter and receiver in optimal relative position;
    • Equipped with red/green LED indicators to clearly show the current working status of the safety light curtain.



    Safety light curtain installation instructions
    Note: The installation position refers to the position of the safety light curtain relative to the upper and lower die of the machine. That is, under the premise of ensuring the safety distance, the last light of the safety light curtain shall not be higher than the lower edge of the lower die, and the upper beam shall not be allowed. Below the upper edge of the upper die. This involves the safety light curtain protection height

    Calculation of safety distance 
    In order to ensure the operator's personal safety, the installation position of the safety light curtain must meet the requirements of the safety distance. Otherwise, there is still the possibility of an accident.
    ◆ Safety distance refers to the minimum distance between the light curtain and the cutting edge of the die. The calculation method should be calculated according to the formula of the brake method of the press, or refer to the following table.
    ◆ For the press where the slider can brake at any position of the stroke, the safety distance:
    Ds=1.6(T1+T2)
    Where: Ds - safety distance, in meters (m)
               1.6 - Stretching speed of the hand, in meters per second (m/s)
               T1 - response time of safety light curtain, 0.02 seconds (s)
               T2——The braking time of the equipment, that is, the time from the start of braking to the stop of the slider, in seconds (s), measured from the actual braking condition
    ◆ For presses where the slider cannot be stopped at any position of the stroke, the safety distance:
    Ds=1.6Ts
    Where: Ds - safety distance, in meters (m)
               1.6 - Stretching speed of the hand, in meters per second (m/s)
               Ts - the time from when the person leaves the light curtain (that is, the slider is allowed to start) until the device slider reaches the bottom dead center, that is, the down travel time of the slider, in seconds (s), can be calculated according to the following formula or actually measured:
    Ts=(1/2+1/N)T
    Where: N - the number of engagement slots of the clutch
               Tn - the time the crankshaft makes one revolution, in seconds (s)
