IP68 Connectors
Filter products
Connector type
The connector type can be used to distinguish our products for installation in a device housing from cable parts. The connector type describes the difference between connectors that are mounted on enclosures, connectors that are mounted on cables, and other connection componentsdistributing signal and power.
Number of contacts
This indicates the number of contacts the connector has.
Gender
A connector consists of the male part (pin) and the female part (socket). Depending on the design, the male or female part is either permanently installed or are located at the end of a cable.
Version
The choice of version allows the definition of the cable outgoing.
Locking Type
The locking system describes how the pin and socket elements are joined.
Termination
The termination type determines how cables, single wires or PCBs can be joined with the connector.
Coding
The connector elements, pin and socket, must be brought into form-fitting alignment with one another (coding) before locking. This prevents mismating.
Shielded Option
Electromagnetic compatibility (EMC) means that a connector is shielded or shieldable. This is required when it is necessary to protect the signals or data conducted by the connector, as well as to protect external devices, from disturbance due to electromagnetic effects.
Material of housing
Depending on the area of application or requirements, connectors are made of different materials. We offer metal and plastic housings for our items as the housing material.
Approval
Our articles have various approvals which can be preselected here. can be preselected here.
Rated current
The rated current is the electrical current that is assigned to the connector.
Rated voltage
The rated voltage is the electrical voltage assigned to the connector.
Locking material
Depending on the technical requirements or performance data of the connector, the locking mechanism is made of plastic or metal.
Cable length
Our items with molded or pre-assembled cables have different cable lengths. It describes the length of the cable from the end of the connector. If the desired cable length is not included, please contact our sales department.
Cable type
By selecting the cable type, a preselection for the respective application can be carried out.
Cable Jacket Type
The material of the cable jacket. PUR, TPE, TMPU or TPE-U cables each have different technical properties.
Cable color
The color of the cable jacket.
Industry
The most important sectors recommended for the requirements, standards and typical applications of the corresponding binder articles.
Single wire length
The stranded wire is an electrical conductor consisting of thin individual wires and is therefore easy to bend. The individual wires of the stranded wire are usually enclosed in a common insulating sheath and come in different wire lengths.
Mounting orientation
The mounting orientation for flange connectors defines the side from which an item can be mounted.
Mounting thread
There are different thread sizes for the device-side connection, depending on the design. These are available in different variants.
Cross section
The connection cross-section defines the possible size of a stranded wire on a contact in the flange or field attachable connector. Cross-sections from 0.08mm² to 6.0mm² are possible here. Since various industry are also using wires according to the American Wire Gauge (AWG), both units are reflected.
Cable outlet
Field attachable connectors can be assembled with different cables. The cable aperture indicates the possible cable diameters that can be used on an article.
Series
The series indicates the product category of binder circular connectors and serves as a guide for selection.
Contact Plating
The contact surface refers to the plating of the contacts (e.g., gold or silver) and affects conductivity, corrosion resistance, and the service life of the circular connector.

IP68 Connectors

IP68 connectors are designed for the most demanding industrial and outdoor applications. With a wide range of variants and configurations, binder offers solutions for virtually every use case, providing dust-tight connections that can withstand continuous immersion in water, ensuring reliable operation of sensors, machinery, and automation systems.


IP68 protection for continuous immersion


Our IP68 connectors provide complete protection against dust and continuous immersion in water. They deliver long-lasting, stable connectivity even under extreme industrial conditions. The extensive portfolio covers everything from compact connectors for sensors to high-performance connectors for machinery and automation systems, combining robustness, reliability, and ease of installation.


Applications involving constant exposure to water or permanently damp environments typically require IP68-rated connectors. These include submerged sensor systems, water treatment facilities, or installations in areas where moisture is continuously present. Under such conditions, protection levels like IP67 are not sufficient to guarantee long-term performance.


It is important to note that IP68 is defined by specific test parameters, including immersion depth and duration. As a result, performance can vary depending on the application requirements. Choosing the right IP68 solution therefore involves aligning the connector specifications with the actual environmental conditions to ensure reliable and continuous operation. However, depending on the requirements, IP65, IP67, or IP69K could also be a relevant option.


Applications of IP68 connectors


• Industrial automation and robotics
• Factory machinery and production equipment
• Outdoor sensors and measurement systems
• Harsh industrial environments

Frequently Asked Questions (FAQ) - IP68


What does IP68 mean for connectors?


IP68 means the connector is fully dust-tight and withstands continuous immersion under manufacturer-defined conditions (immersion depth and duration).


Are IP68 connectors fully waterproof?


They are designed for continuous immersion, but always in relation to defined test conditions such as depth and duration. The specific limits must be checked per application.


What is the difference between IP67 and IP68?


IP67 protects against temporary immersion (up to 1 m, 30 minutes), IP68 against continuous immersion under manufacturer-defined conditions that exceed IP67.


Where are IP68 connectors used?


In submerged sensor systems, water treatment and permanently damp environments where lower protection ratings do not provide sufficient reliability.

Are IP68 connectors suitable for continuous immersion?


Yes, provided the application stays within the manufacturer-specified immersion depth and duration. For high-pressure or hot-water cleaning, IP69K is additionally required.
