If you’re sourcing EV connectors for charging stations, vehicle manufacturing, or battery management systems, here’s what you’ll find at the OX Connections booth—and how we help you avoid the 12–16 week import wait.
We’re displaying our complete circular connector range at Hall 8, Booth W141, February 25-27, 2026. From compact M16 for BMS sensors to heavy-duty M30 for high-power distribution, we stock the full range in India. Discuss your requirements at our booth, and we can typically dispatch within days.
M23 Circular Connectors for EV Applications
M23 circular connectors provide robust power and signal connections suitable for EV charging equipment, vehicle wiring, and battery management systems. Our booth displays:
M23 Panel Mount Connectors: 12-pin and 17-pin configurations handling both power distribution and control signals. Threaded coupling provides secure mechanical lock and environmental sealing. Common in charging station installations and vehicle-side connections.
M23 Cable Connectors: Mating counterparts for panel-mount versions. Available in straight and right-angle configurations for different cable routing requirements.
Technical Specifications — M23 Series:
| Parameter | Specification |
| Pin configurations | 12-pin, 17-pin, 19-pin options |
| Current capacity | Up to 16A per contact (varies by pin size) |
| Voltage rating | Up to 630V |
| IP rating | IP67 when properly mated |
| Contact material | Silver-plated or gold-plated copper |
| Housing | Metal or high-grade plastic options |
| Operating temperature | -40°C to +125°C |
M23 connectors feature keyed housing preventing incorrect mating and ensuring proper pin alignment. The threaded coupling nut creates gas-tight connections resistant to vibration—critical in vehicle applications.

Applications in EV Charging Infrastructure
DC Fast Charging Stations: High-current circular connectors for power distribution within charging cabinets. M25 and M30 series handle main power connections between rectifier modules and charging outputs.
AC Charging Stations: M20 and M23 connectors for control signals, communication interfaces, and auxiliary power distribution. Reliable connections critical for smart charging features and remote monitoring.
Charging Cable Assemblies: Circular connectors at equipment end of charging cables enable field replacement and maintenance. Panel-mount connectors on charging stations mate with cable assemblies for secure, weatherproof connections.
Power Distribution Units: EV charging sites with multiple charging points use circular connectors for organized power distribution from main supply to individual charging stations.
Applications in Vehicle Manufacturing
Battery Management Systems (BMS): Circular connectors link BMS controllers to cell monitoring modules, current sensors, and safety disconnect systems. Multi-pin M23 connectors consolidate signals in single connection point.
Motor Controller Connections: High-current circular connectors for three-phase motor power, encoder feedback, and control signals. M23 and larger sizes handle power while maintaining signal integrity for control circuits.
Onboard Charger Connections: Vehicle charging systems use circular connectors for AC input connections, DC output to battery, and communication with vehicle network. Robust connectors withstand under-hood thermal and vibration environment.
Auxiliary Power Distribution: 12V/24V auxiliary systems in EVs use circular connectors for modular wiring—lighting, HVAC, infotainment systems. Standardized connectors simplify harness assembly and vehicle servicing.
Sensor and Communication Networks: CAN bus, LIN bus, and sensor networks throughout vehicle use circular connectors for reliable signal connections. Shielded connectors prevent electromagnetic interference in electrically noisy EV environment.
Why Connector Reliability Matters in EV Applications
EV systems operate at voltages (typically 400V, 800V systems) where even small connection resistance causes significant power loss and heat generation. A connector with 10 milliohms resistance carrying 100A generates 100W heat—enough to degrade connection over time.
Environmental exposure is severe in EV applications. Charging stations face outdoor weather exposure. Under-hood vehicle connections experience temperature extremes, vibration, and potential exposure to moisture or contaminants. Connector IP ratings and robust construction are functional requirements, not premium features.
Safety considerations are critical. EV systems carry voltages and currents capable of causing harm. Connectors must prevent accidental contact, withstand fault conditions, and maintain insulation integrity. Keyed housings, secure locking, and proper insulation ratings are essential safety features.
Selecting Circular Connectors for EV Applications
Current Requirements: Calculate maximum continuous and peak currents. Select connectors with adequate current capacity including safety margin. Operating near connector limits accelerates degradation.
Voltage Rating: Ensure connector voltage rating exceeds system voltage with margin. For 400V battery systems, use connectors rated 600V or higher.
Environmental Protection: Match IP rating to exposure conditions. IP67 suitable for most applications; IP68 or IP69K for washdown areas or submersion risk.
Pin Count: Consolidate power and signals where possible to reduce connector count, but maintain separate paths for safety-critical signals.
Keying and Polarity: Use mechanically keyed connectors preventing incorrect mating. In EV applications, reversed polarity can damage expensive components.
