The IP and IK grades of capacitive touch screens are important indicators to evaluate their protection performance. The IP Rating (Ingress Protection Rating) is used to evaluate the capacitive touch screen's Protection ability against solid objects and liquids, while the IK rating (Impact Protection Rating) is used to evaluate the capacitive touch screen's impact resistance to external forces. These two levels are described in detail below.
IP Rating (Ingress Protection Rating) : The IP rating identifies the protection ability of capacitive touch screens against solid objects and liquids. It consists of two numbers that represent different levels of protection. The first number indicates the level of protection against solid objects, ranging from 0 to 6; The second number indicates the level of protection against liquids, ranging from 0 to 9.
Level of protection against solid objects (first number) :
IP0X: No special protection, no protection capability.
IP1X: It has certain protection ability for solid objects with a diameter greater than 50mm.
IP2X: Has a certain protection ability for solid objects with a diameter greater than 12.5mm.
IP3X: Has a certain protection ability for solid objects with a diameter greater than 2.5mm.
IP4X: It has certain protection ability for solid objects with a diameter greater than 1mm.
IP5X: Has a certain protection ability against dust, but cannot completely prevent dust from entering.
IP6X: has very high protection against dust, completely prevents dust from entering.
Level of protection against liquids (second number) :
IPX0: No special protection, no protection capability.
IPX1: Has certain protection against vertical dripping.
IPX2: It has certain protection ability against inclined dripping within 15 degrees.
IPX3: It has certain protection ability to spray water within 60 degrees.
IPX4: It has certain protection against splashing water in any direction.
IPX5: It has certain protection ability against low pressure water spraying.
IPX6: It has certain protection ability against strong water spraying.
IPX7: can work in a water depth of 1 meter in a short time.
IPX8: Works for long periods of time or deeper underwater.
IK (Impact Protection Rating) : The IK rating is used to assess the impact resistance of capacitive touch screens to external forces. It consists of a number that ranges from 0 to 10, with higher numbers indicating greater impact resistance.
IK0: No special protection, no impact protection.
IK1: Provides some protection against the impact of 1.7 joules (0.5 kg of objects hitting at 10 cm/s).
IK2: Provides some protection against the impact of 3.4 joules (a 1 kg object hitting at a speed of 10 cm/s).
IK3: Has some protection against the impact of 5.1 joules (1.5 kg object hit at 10 cm/s).
IK4: Provides some protection against the impact of 6.8 joules (a 2 kg object hitting at a speed of 10 cm/s).
IK5: Provides some protection against 11 joules (5kg objects hitting at a speed of 10 cm/s).
IK6: Has some protection against the impact of 20 joules (10 kg objects hit at 10 cm/s).
IK7: Provides some protection against the impact of 40 joules (a 20 kg object hitting at a speed of 10 cm/s).
IK8: Provides some protection against the impact of 80 joules (40 kg objects hitting at a speed of 10 cm/s).
IK9: Provides some protection against the impact of 170 joules (68 kg objects hitting at 10 cm/s).
IK10: Provides some protection against the impact of 340 joules (100 kg objects hitting at 10 cm/s).
Summary: IP and IK grades are important indicators for evaluating the protective performance of capacitive touch screens. The IP rating indicates its protection ability against solid objects and liquids, and the higher the number, the stronger the protection ability; The IK rating indicates its ability to withstand external shocks, and the higher the number, the stronger the impact resistance. The existence of these grades helps users select capacitive touch screen products that suit their specific needs and ensure their reliability and stability in a variety of environments.
