Outdoor Display keypads are a huge craze today, due to their multiple uses and long shelf life. Here is a look at their various advantages: |
1. These are made from solid metals and are rugged outdoor environment compatible. The screen is vandal proof, explosion proof and cannot be dented with a screwdriver or a hammer. These are also vibration and impact proof.
2. These keypads have an ultrasonic mode installed in them that makes them that makes them sensitive to finger touch and gloves touch but protects from water. In fact, these can be easily used for any kind of underwater work.
3. The most difficult issue to be solved in harsh, outdoor environments is that of sealing. Most of the display keypads come with in-built sealing points and there is no need for installing external sealing points. Most of these come in a closure, panel or bezel etc.
4. Most of the rugged keypads have microprocessors installed in them for touch sensitivity. The touch circuit is designed in such a way that it is highly tolerant to the other electronic noises. This makes the display sensitive to even the lightest of the touches. The microprocessor also keeps track of whether the touch is working properly or not. It keeps track of all the anticipated failures as well. This property makes these keypads apt for remote and critical applications.
5. Most of these keypads are apt for the outdoor environments like storms, rains, heat, dust etc. These are also impervious to water and can be used in a wide range of temperature. The range in which these can work is -40 to +85 Celsius. Some of the Outdoor keypad may also work in a range of -60 to 125 Celsius.
6. Multiplexing is very easy in these keypads. The switches can be directly multiplexed to the microprocessor. Continuous signals are produced when a switch is pressed. The sensing power of these keypads is also very fast.
7. Display keypads are the best choice for any kind of mission critical application. These are the best choice for harsh environments and are very reliable. Their various components are fabricated with robust, solid materials. This makes them resistant to liquids and hence, these are the best suited for food processing units and the pharmaceutical units. These are also protected from other type of contaminants. Most of the display keypads have no moving parts and this fact makes them very reliable.
