M5 Circular Connectors
M5 connectors deliver sealed, high-density signal connections in compact spaces. EI Sales sources rugged circular models ideal for sensor clusters, embedded systems, and automation equipment.
M5 Connector Variants Available
EI Sales features a wide selection of M5 connector configurations tailored to your exact integration needs. These compact connectors are built to maintain signal reliability in environments where vibration, ingress, and alignment challenges are common.
3 and 4-Pin Configurations
Standardized layouts support low-voltage signal and power lines, ideal for miniature sensors and control applications. These pin counts are widely supported across sensing platforms, making them easy to integrate into existing designs.
A-Code and B-Code Options
Industry-recognized coding formats allow for safe, keyed mating that supports proper pin assignments in sensor and data interfaces. Using coded connectors also reduces the risk of cross-mating during installation or maintenance.
Shielded and Unshielded Models
Shielded variants provide enhanced signal clarity in EMI-heavy environments such as control cabinets or robotics. Unshielded models offer a cost-effective option for less sensitive applications where space and simplicity are priorities.
Male and Female Threaded Coupling
Threaded locking supports secure engagement and resists vibration and accidental disconnects in motion-heavy assemblies. These connectors are often chosen for mobile or high-cycle environments where signal integrity must be preserved.
Straight and Right-Angle Designs
Available in straight or right-angle configurations to fit tight enclosures and align along PCB edges. This flexibility simplifies mechanical layout and streamlines servicing during prototyping or updates.
Panel Mount and Overmolded Cable Assemblies
Available in discrete panel-mount and preassembled overmolded cable versions for fast deployment. Overmolded options improve ingress protection and reduce assembly labor in production environments.
IP67 and IP68 Sealed for Harsh Environments
Ingress protection ratings up to IP68 guard against moisture and dust in demanding settings. These ruggedized connectors are ideal for washdown areas, outdoor systems, and medical equipment requiring frequent sterilization.

Customers benefit from EI Sales wide range of experience in industries that utilize electronic components and assemblies. This knowledge not only helps EI Sales achieve market growth and sales results for its principals, but allows them to provide superior service and product advice and recommendations to customers, resulting in strong, profitable relationships.
Miniature Sensors and Actuators
M5 connectors are a go-to interface for miniature devices that require dependable connections in tight locations. They simplify signal routing for sensor clusters and modular assemblies where space is limited.
Industrial Automation & Robotics
Used across robotics arms, conveyor systems, and PLCs, these connectors withstand motion, vibration, and electrical noise. Their secure threading and compact size reduce maintenance and downtime in industrial settings.
Medical and Laboratory Equipment
M5 connectors meet medical requirements for compact, sealed interfaces that hold up to frequent cleaning and equipment repositioning. They are commonly used in monitoring devices, handheld instruments, and test equipment.
Vision Systems and Control Panels
In machine vision and display interfaces, M5 connectors support clear signal transmission in tight panel spaces. Shielded versions are available for use near drives or RF-emitting components.
Light Barriers and Proximity Switches
Their small footprint and consistent contact make them ideal for optical sensors and detection systems. Prewired options reduce installation steps and help maintain sensor alignment across cycles.
Space-Constrained Embedded Systems
From board-mounted controllers to compact field devices, these connectors enable precise signal connections without overloading PCB layouts. Straight and right-angle versions support flexible cable routing inside enclosures.
