Product Description
As their name suggests, distance sensors are used for determining the distance of an object from another object or obstacle without any physical contact involved (unlike a measuring tape, for example). Commonly associated with ultrasonic sensors, it functions by outputting a signal (depending on technology: ultrasonic waves, IR, LED, etc.) and measuring a change when the signal returns.

The sensor measures distances without contacting the measured surface, thus eliminating wear and associated errors. It features a case hardened chassis that is seal from the environment in order to keep dust, water spray, and the weather out of the optical systems. The measured object can be a solid, energy absorbing or radiating hot body. Especially measurements on natural surfaces with low reflectivity are also possible. The laser distance sensors even can measure distances to or from moving objects.

HC-G50 laser distance sensor uses laser diode emitting the Infrared light, to measure distances by measuring the phase shift of the returning light. The ability to measure with accuracy of millimeter within 50m is realized by the proven phase comparison method.
The HC-G50 laser distance sensor can measure targets from 0.3m up to 50m without the use of reflective targets. It can work with any opaque target. The HC-G50’s accuracy is typically ± 1mm, but this will depend on the reflectivity of the target surface, ambient light, and temperature conditions. For very distant measurements, you can use retroreflective target material (such as 3M Scotchlite 3279) to increase the maximum measurement range to 150meters.
Working Principle
IR distance sensors, short for infrared, it does distance sensing through emitting IR wave and calculating the angle of reflection. IR sensors come with two lenses: * IR LED emitter lens that emits a light beam * A position-sensible photodetector (PSD) where the reflected beam will fall onto
It work through the principle of triangulation: measuring distance based on the angle of the reflected beam.
1. Infrared light is emitted from the IR LED emitter 2. The beam of light hits the object (P1) and is reflected off a certain angle 3. The reflected light will reach the PSD (U1) 4. The sensor in the PSD will then determine the position/distance of the reflective object

Laser diode
The HC-G50 has a Class 2, red, visible laser diode for simple aiming and setup. The spot size is 7.8mm as the light leaves the laser, and the beam has a divergence of 0.6milliradians. 650nm, 1mW visible RED laser, complies with 21CFR 1040.10 with Laser Notice 50, IEC/EN60825-1:200

Precise and efficient
It features a case hardened chassis that is seal from the environment in order to keep dust, water spray, and the weather out of the optical systems. Within a range of 50m, the HC-G50 laser distance sensor is capable of measuring with millimeter precision on natural surfaces.
Measurement stability
The stability of the measured values can also be guaranteed on rough and structured surfaces thanks to the fine line beam shape. Thus, not the structure itself, but the object to be measured can be reliably measured. It work according to the principle of angle measurement, whereby color, shape and object surface do not influence the measurement.
ABS aviation joint
The protective joint with good sealing performance is waterproof and dust-proof, aging resistant, and high and low temperature
resistant. And the port is glue-pouring sealing with high-density epoxy resin, which can prevent moisture from entering the body.

Outputs and inputs
You can choose a standard RS232 or optional RS422 serial interface for communication with a computer or PLC. The HC-G50 also comes with a standard, 4-20 mA, analog, current loop output.

Imported chip
The chip with imported processor is to ensure the low power consumption, high sensitivity, strong anti-interference ability, a higher signal-to-noise ratio, and a more stable and sensitive signal, it also features virtually immune to shock loading, strong resistance to electromagnetic interference.
