IP protection (contact protection, dust, water)
The connector’s housing, sealing and locking mechanism protect the connection from external influences such as mechanical shocks, foreign bodies, humidity, dust, water or other fluids such as cleansing and cooling agents, oils, etc. The degree of protection the housing offers is explained in the IEC 60 529, DIN EN 60 529, standards that categorize enclosures according to foreign body and water protection. The following table shows the different degrees of protection.
First Index Figure
Foreign bodies protection
No protection (against accidental contact, against solid foreign bodies)
Protection against large foreign bodies (Ø > 50 mm), Protection against contact with any large area by hand
Protection against medium sized foreign bodies (Ø > 12 mm), Protection against contact with the fingers
Protection against small solid foreign bodies (Ø > 2.5 mm), Protection against tools, wires or similar objects with Ø > 2.5 mm
Protection against grain-shaped foreign bodies (As 3 however Ø > 1 mm)
Protection against injurious deposits of dust (Full protection against contact, Protection against interior injurious dust deposits)
Protection against ingress of dust (Total protection against contact. Protection against penetration of dust)
