Why Engineers Choose Bahar Enclosure

Choosing an enclosure involves more than selecting an IP rating. Engineers and purchasing teams also need consistent dimensions, dependable material quality, suitable internal space, practical installation features, and access to customization services.

Bahar Enclosure supports projects ranging from prototypes and small orders to customized production requirements.

Customers can review available standard models first and then request modifications based on their drawings and project specifications.

Understanding IP Ratings for Waterproof Enclosures

One of the most important factors when selecting a plastic waterproof enclosure is its Ingress Protection rating.

The IP rating is defined under the IEC 60529 standard and describes the degree of protection an enclosure provides against access to hazardous parts, solid objects, dust, and water.

The first digit relates to protection against solid objects and dust. The second digit relates to protection against water.

For example:

The number 6 in IP65, IP66, IP67, and IP68 indicates dust-tight protection.
The second digit indicates the type and level of water protection.

An IP rating applies to the tested enclosure configuration and conditions. Drilling holes, installing unsuitable cable glands, damaging the gasket, using incorrect screws, or modifying the enclosure can affect the final protection level.

For official information, refer to the IEC 60529 IP Code publication.

IP65 vs IP66 vs IP67 vs IP68
IP65

Dust protection: Dust-tight
Water protection: Protection against water jets
Typical applications: Indoor industrial installations, sheltered outdoor systems, electrical controls, and equipment exposed to dust or occasional water jets.

IP66

Dust protection: Dust-tight
Water protection: Protection against powerful water jets
Typical applications: Outdoor electrical equipment, industrial cleaning environments, control systems, and installations exposed to stronger water jets.

IP67

Dust protection: Dust-tight
Water protection: Protection against temporary immersion under defined test conditions
Typical applications: Outdoor sensors, monitoring equipment, electrical connections, and installations with possible temporary water exposure.

IP68

Dust protection: Dust-tight
Water protection: Protection against immersion under conditions agreed or specified by the manufacturer and applicable test requirements
Typical applications: Demanding outdoor systems, marine-related equipment, solar installations, remote sensors, and projects requiring enhanced immersion protection.

IP68 does not automatically mean that every enclosure can remain at any depth for an unlimited period. The exact immersion depth, duration, enclosure configuration, and test conditions must be confirmed.

Selecting the Correct IP Rating

The highest IP rating is not always necessary for every application. The correct selection depends on actual operating conditions.

Consider:

Is the enclosure installed indoors or outdoors?
Will it be exposed to rain?
Will it be cleaned using water jets?
Is temporary flooding possible?
Will it be immersed?
What cable glands and connectors will be installed?
Will the enclosure be opened frequently?
Can pressure or condensation build up internally?
Will the enclosure be installed vertically or horizontally?

For a sheltered indoor installation, an IP65 model may be sufficient. For exposed outdoor equipment, IP66 or IP67 may be more suitable. Applications involving immersion may require a verified IP68 solution.
