Sommaire

What Does IP Rating Mean?

IP stands for Ingress Protection, defined by IEC standard 60529. An IP rating has two digits: the first indicates protection against solid particles (dust), the second against liquids (water).

IP Rating Breakdown

Rating	Dust Protection	Water Protection	Typical Application
IP54	Dust protected	Splashing water	Light industrial, outdoor kiosks
IP65	Dust tight	Water jets (12.5 mm nozzle)	Factory floor, general industrial
IP66	Dust tight	Powerful water jets	Food processing, outdoor
IP67	Dust tight	Temporary immersion (1m, 30 min)	Wet processing, chemical plants
IP69K	Dust tight	High-pressure steam cleaning	Dairy, pharma, abattoir

Which IP Rating Do You Need?

General factory floor (machining, assembly), IP65 minimum
Food & beverage (daily hose-down), IP66 or IP67
Pharmaceutical, dairy, beverage (steam/chemical wash), IP69K
Outdoor installations, IP66 minimum
Cold storage (condensation risk), IP65 with heater option

IP (Ingress Protection) rating is an IEC 60529 standard that classifies the degree of protection an enclosure provides against solid particles (first digit, 0 à 6) and liquids (second digit, 0 à 9K). For example, IP65 means fully dustproof (6) and protected against water jets from any direction (5). IP ratings are critical for specifying industrial computers, HMI panels, and sensors for factory environments.

IP65 front panel sealing is the minimum recommended for industrial HMI panels on production floors, fully dustproof and protected against water jets. For food, beverage, and pharmaceutical wash-down areas, specify IP66 (powerful water jets) or IP69K (high-pressure steam cleaning). The IP rating must apply to the installed front face of the panel in the control cabinet cutout, verify the complete system rating, not just the device in isolation.

IP65: dustproof + protected against water jets (12.5 litres/minute at 6.3kPa from any direction). IP66: dustproof + protected against powerful water jets (100 litres/minute at 100kPa from any direction). IP69K: dustproof + protected against high-pressure, high-temperature steam jets (80°C water, 80 à 100 bar, 14 à 16 litres/minute at close range). IP69K is required for steam cleaning in food, beverage, and pharmaceutical facilities.

No, IP rating only specifies protection against solid particle and liquid ingress. Operating temperature range is a separate specification. An IP65 device may only be rated for 0°C to 50°C operation, which would be inadequate for a cold storage facility. Always check both the IP rating and the operating temperature range against your installation environment.

Yes, Cermate HMI panels typically have IP65 front panel sealing (IP66 on selected wash-down models). Avalue industrial Panel PCs have IP65 front panels as standard, with IP66 and IP69K stainless steel options for hygiene-critical environments. TSL Automation Solutions can confirm the exact IP rating for specific models. Contact our Mumbai team with your environment requirements.
