Safety light curtain sensor device

1. Principle: The light emitted by the emitter is directly directed to the photoreceiver, forming a protective light curtain. When the light curtain is blocked,
the light receiver generates a light blocking signal, which is transmitted to
through the signal cable to give the signal required by the equipment
or an intermediate relay is added, and the relay gives the signal required by the equipment
br/> Signal.
The series of universal safety gratings adopt unique optical synchronous scanning technology, with powerful functions.
Complete self-checking functions, simple to use, safe and reliable, within response time,
distance up to meters, suitable for Use in a variety of environments.
Compared with traditional solutions, series of safety gratings can make your safety more
guaranteed and more assured. The product has passed third-party certification! The automatic shielding and setting shielding function can be customized, and it comes with dual independent transistor safety outputs. The controller can also be configured to provide safety relay signal output.
2. Performance characteristics
Self-test
The grating adopts self-test. When the grating itself fails (such as the light source is not synchronized, the light source intensity is not enough, the light emission drive circuit is wrong, the main control circuit is wrong, In the event of a cable problem, an error in the receiving drive circuit, or an error in the main control circuit, the error grating can ensure that no error signal is sent to the controlled device, ensuring the safety of the grating
Dual independent outputs
In terms of output, In pursuit of better safety, dual independent redundant outputs are adopted, which makes automatic fault prevention highly safe and can directly drive safety relays and safety
External relay contact bonding protection function
When the output signal of the light grid needs to be connected to the customer's ordinary relay/contactor equipment, in order to ensure the safety of the entire system, the safety light grid has the function of monitoring the status of the external relay contacts to prevent failure due to external relay bonding failure. Resulting in the loss of safety protection functions
Super anti-interference ability
Adopting infrared communication and special optical system, strong anti-interference ability (good immunity to electromagnetic signals, strobe lights, welding arcs and surrounding light sources) Anti-interference ability)
More responsive response
The response time of all grating products in this series is within overload and short-circuit protection. When the safety grating output is overloaded or short-circuited, the grating will enter the protection state, and the grating safety system will be closed at the same time. Self-test: Implement self-test within seconds of power-on to ensure that there is no fault. Power-on delay function
Only seconds after power-on can the grating operate normally, providing safety to the operator and the equipment. A buffer time improves the safety of equipment and personnel
Blind zone filtering function
When an object passes through the light curtain slowly, the grating always outputs a stable disconnect signal, which prevents the machine from starting accidentally and makes production more efficient. Safe and reliable
Optical synchronization technology
Unique optical synchronization technology replaces traditional data line synchronization to avoid signal interference and eliminate long data line connections
