Machine safety light curtain

Safety light curtains, safety grating one, direct light emitted by the light emitter principle to the optical receiver, forming a protective curtain. When the light curtain is blocked, the light generated by a light shielding signal processing signals transmitted by cable to the controller, the controller of this signal, generates a control output signal to control the machine's brake control circuit or other device alarms, machine tool to stop running or security alarm. Second, photoelectric protection device component units: a light emitting device: by a number of light-emitting device composed emits infrared light; Receiver: receiving by a number of optical components, receiving the infrared light, and the light-emitting device emitting device correspondence, forms a protective curtain, produce through light, shading signal, the signal transmitted through the signal cable to the controller to control external devices; controller: a signal processing unit, a light emitting device, the light provides power and receives light through shading signals transmitted by the optical device, generating an output control signal to control the brake control circuit or other device alarm machine, to achieve the machine stops running or security alarm. ES-I-type controller has a built-in controller, ES-P-type external controller and ES-II double-loop two types of built-in controller, built-in controller compact structure, can be installed in the control box equipment beautiful and strong external controller structure, can be installed directly on the device, easy operation and observation of light through curtains, blackout state;; the optical device + receiving light ES-P external controller ES-I by the built-in controller ES -II dual loop controller signal cable: to transmit controller and a light emitting device, the signal light between the subject; a control cable: used to connect the controller and machine tools, equipment, in order to achieve security control machine tools or other equipment; mounting bracket : The light emitter and the light is fixed in the table; three characteristics of photoelectric protection device to protect Length: 0-3500mm protective height: 50mm to 3120mm, other height can be customized; optical axis pitch: 10mm, 20mm, 40mm, 80mm, other spacing can be customized ;; perfect self-test function: using the latest security technology design, when optoelectronic protective devices or loss of power itself fails to ensure that the control of the electrical control signals an error; LED working status and error display : The LED digital display and LEDs, can clearly show the operating status and anomalies; long-life dual relay output control: The controller uses imported high reliability double relay control, the electrical life of more than one million times, the relay reached the life After replaceable; anti-interference ability: the electromagnetic signals, strobe light, welding arc and the surrounding light source has a good anti-jamming capability; self-protection function (built-in controller): block the light behind the light curtain has remained off state, only press the reset button, light curtain of light through state recovery. Fixed blind (order): Allows the system can be ignored by setting the detection area visible some fixed object (such as a stent, fixtures, etc.) to ensure the presence of these objects does not affect the operation of the machine. Floating blind (E3B Series) (order) allows setting allows some beams masked, these beams can fluctuate, you can ignore some of the region within the system detects moving objects visible, to ensure the presence of these objects does not affect the operation of the machine.
