The iSENSOR i12 Advantage: Sealed M12 Connection and Threaded Coupling Design

IP69K Industrial Automation Connector

Rated IP67, IP68, and IP69K, the iSENSOR i12 supports applications requiring resistance to dust, immersion, and high-pressure cleaning.

Threaded M12 Connector Design

A secure threaded coupling provides stable mating for M12 sensor and control devices used in automation and other industrial environments.

Versatile Electrical Capability

With voltage ratings up to 300 V (RMS) and amperage ratings up to 13 A, the iSENSOR i12 adapts to a range of power and signal requirements.
Configured for Your Application Requirements
The iSENSOR i12 can be built with your choice of contact terminations (crimp or PC-tail), insert types, and overmold orientations, including straight or right-angle designs with optional strain relief. Coupling rings are available in multiple colors, and blue silicone O-rings provide visible confirmation of sealing.

Design Details: Quality Construction for Optimal Performance

Connector Construction

The iSENSOR i12 is constructed using glass-filled PBT housings and coupling nuts, a material known for its strong dimensional stability and resistance to mechanical wear. A neoprene mounting gasket and silicone O-ring support consistent sealing. The connector’s CU-alloy contacts with gold-over-nickel plating help maintain reliable conduction and protect the contact surfaces from oxidation. Overmold materials vary by cable selection, including PVC, TPU, and more.

Core Technical Benefits

Gold-Plated Contact System: CU-alloy contacts plated with gold over nickel help maintain durable, low-resistance electrical performance over time.

Multiple Contact Configurations: Available with up to eight #20 contacts or five #16 contacts, allowing the connector to support varied wiring and circuit layouts.

Temperature-Resilient Construction: Supports continuous operation between 80 °C and 105 °C, depending on wire/cable and overmold material selection.

Closed-Entry Design Options: Female inserts incorporate a closed-entry design that supports proper alignment and guided mating during connector engagement.

Suitable Applications for iSENSOR i12 M12 Circular Connectors

Sensor and Control Devices

Ideal for proximity sensors, encoders, switches, and other field-mounted components that rely on M12 threaded connections for dependable operation.

Automation and Equipment Assemblies

Suitable for automated machinery that uses M12 connectors to interface with sensing, control, or monitoring devices throughout the equipment.

Material Handling and Packaging Systems

Well-suited for conveyors, packaging lines, and handling equipment where sealed M12 connections are needed to withstand dust, vibration, and washdowns.

Outdoor and Environmental Monitoring

A good fit for weather-exposed sensing and monitoring equipment that requires a sealed M12 interface to handle moisture and changing conditions.

iSENSOR i12: Dependable M12 Connectivity for Industrial Systems

The iSENSOR i12 provides a sealed M12 circular connector solution with validated IP protection and multiple configuration options for sensing and control applications. Its threaded interface and flexible contact selections support stable performance in industrial and outdoor environments.

Backed by iCONN Systems’ capabilities in engineered interconnects and cable assembly manufacturing, the iSENSOR i12 offers reliable and configurable connectivity for a wide range of automation and monitoring systems.
