Garantta introduces the GPS-R61/R81 Square Mirror Retro Reflective Type Sensor, employing the retroreflective principle with a unified transmitter and receiver. Stable detection is achieved with the help of a reflector. This sensor supports NPN (GPS-R61) and PNP (GPS-R81) output options, adapting to various automated control systems.
Effortless installation and one-step commissioning. Simply install the reflector on the opposite side of the measured path; unlike through-beam sensors, precise alignment of the two side brackets is unnecessary, significantly improving installation efficiency. The square housing design features standard mounting holes, suitable for various compact devices.
4-meter long-distance detection with laser-grade accuracy. The GPS-R series boasts a maximum detection distance of 4 meters, far exceeding comparable diffuse reflection products. The laser light source provides a precise and stable spot, unaffected by the surface color and material of the measured object, achieving stable output even for difficult-to-detect targets such as transparent bottles and thin film packaging.
Detection principle of Retro Reflective Type Sensor
Garantta mirror reflection photoelectric sensor mainly uses the reflection principle to complete the photoelectric control function. Its light emitter and light receiver are in the same device, and a reflector is installed in front of it. Under normal circumstances, the light emitted by the light emitter will be reflected back by the reflector and received by the light receiver; once the light path is blocked by the detected object and the light receiver cannot receive the light, it will output a switch control signal.
Advantages of Retro Reflective Type Sensor
Our Garantta mirror reflection photoelectric sensor is easy to install and debug. The terminal block can be quickly installed through the bracket, and the reflector can be installed by pasting or clamping. Although its detection distance is not as good as that of the through-beam photoelectric sensor, it is much better than the diffuse reflection photoelectric sensor of the same specification.
When a certain detection distance needs to be guaranteed, but the installation space is not enough, the mirror reflection photoelectric is the best choice; even if there is enough installation space, if the ultra-long detection distance is not required, the use of mirror emission photoelectric sensors can greatly save costs.
Our Garantta mirror reflection series photoelectric sensors are not only sturdy and durable but also have strong anti-interference ability, and the actual detection distance is better than most similar products on the market.
Not only dustproof and waterproof but also not afraid of light interference. They can work normally at low temperatures of minus 25 degrees and high temperatures of 55 degrees, and can fully meet the outdoor use standards in non-extreme environments. In fact, in outdoor or dusty scenes such as package industry, food industry and printing industry etc.., our Granta brand mirror reflection photoelectric sensors have been put into use in large quantities.
This Retro Reflective Type Sensor has nothing to do with safety and is mainly used for the detection of workpieces and operators. Safety Points To ensure safety, please be sure to comply with the following items
1. About power supply voltage Do not exceed the operating voltage range during use.
If a voltage is applied above the operating voltage range, or an AC power supply (AC100V or more) is applied to a DC power supply type sensor, it may cause rupture or burning.
2. About load short circuit
Avoid short circuiting the load. Otherwise, it may cause rupture or burning.
3. About connection without load
Because direct connection of the power supply without load may cause internal components to rupture or burn, please be sure to wire with load.
4. About incorrect wiring
Consider the polarity of the power supply, etc., and do not make incorrect wiring. Otherwise, it may cause rupture or burning.
5. About connection without load Because direct connection of the power supply without load may cause internal components to rupture or burn, please be sure to wire with load.
