As far as you like. For example it travels from the sun and gets through our atmosphere without much difficulty.
That depends, short wave infrared radiation can travel through glass (hence the laser pointers and your TV remotes), but longer infrared waves get reflected. This is due to the design of glass so that we can see through it but the infrared heat radiation does not leave, thus improving efficiency.

The question is not correctly phrased, Infrared is electromagnetic radiation which consists of waves. Amplitude is a measure of the maximum "strength" or height of the wave and therefore will have a whole range of values from 0 upwards. Infrared does not have a specific range of amplitude however it will have a range of frequencies ( visible light Red end 4 x 1014 Hertz - 3 x 1011 Hertz Microwaves ) and wavelength (visible light Red end 750 nanometres - 1000000 nm nanometres Microwaves)
Proximity switches open or close an electrical circuit when they make contact with or come within a certain distance of an object. Proximity switches are most commonly used in manufacturing equipment, robotics, and security systems. There are four basic types of proximity switches: infrared, acoustic, capacitive, and inductive. Infrared proximity switches work by sending out beams of invisible infrared light. A photodetector on the proximity switch detects any reflections of this light. These reflections allow infrared proximity switches to determine whether there is an object nearby. As proximity switches with just a light source and photodiode are susceptible to false readings due to background light, more complex switches modulate the transmitted light at a specific frequency and have receivers which only respond to that frequency. Even more complex proximity sensors are able to use the light reflected from an object to compute its distance from the sensor. Acoustic proximity sensors are similar in principle to infrared models, but use sound instead of light. They use a transducer to transmit inaudible sound waves at various frequencies in a preset sequence, then measure the length of time the sound takes to hit a nearby object and return to a second transducer on the switch. Essentially, acoustic proximity sensors measure the time it takes for sound pulses to "echo" and use this measurement to calculate distance, just like sonar. Capacitive proximity switches sense distance to objects by detecting changes in capacitance around it. A radio-frequency oscillator is connected to a metal plate. When the plate nears an object, the radio frequency changes, and the frequency detector sends a signal telling the switch to open or close. These proximity switches have the disadvantage of being more sensitive to objects that conduct electricity than to objects that do not. Inductive proximity switches sense distance to objects by generating magnetic fields. They are similar in principle to metal detectors. A coil of wire is charged with electrical current, and an electronic circuit measures this current. If a metallic part gets close enough to the coil, the current will increase and the proximity switch will open or close accordingly. The chief disadvantage of inductive proximity switches is that they can only detect metallic objects. Proximity switches are used in manufacturing processes -- for example, to measure the position of machine components. They are also used in security systems, in applications such as detecting the opening of a door, and in robotics, where they can monitor a robot or its components' nearness to objects and steer it accordingly BY:ragith
Distomat is an instrument used to measure distance using light and radio waves.
Infrared light is just light of a specific wavelength it can travel as far as any other wavelength of light.
It can travel across the vacuum of space.

Electromagnetic waves, such as infrared and visible light
No. All colors of light, and all other forms of electromagnetic radiation, all travel with the same speed.
'Light-year' is a unit of a distance. It is the distance for light to travel one year. So it is a great distance.
A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles. A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles.
No. A light year is the distance that any light can travel in a year.It's about 63 thousand times the distance from the sun to Earth.The light from the sun takes about 8 minutes to travel to the Earth.
No. The distance from the Earth to the Sun is 8 light-minutes.It takes light 8 minutes to travel from the Sun to the Earth, in other words.The distance that light can travel in one year is one light-year.
27,000 light-years is a distance of 158,720,000,000,000,000 miles. This is the distance light will travel in 27,000 years.
Yes, infrared waves are part of the electromagnetic radiation spectrum and all electromagnetic radiation will propagate through a vacuum.
