M12 Circular Connectors: Engineered for Uninterrupted Security Connectivity
Our M12 circular connectors are purpose-built to deliver reliable power and high-speed data transmission for modern security and CCTV systems, designed to thrive in harsh outdoor environments and high-traffic indoor installations. With a full range of coded types, pin counts, and versatile mounting options including PCB and panel-mount solutions, these connectors ensure your critical security infrastructure stays connected 24/7.
Key Advantages of M12 Connectors for Security Applications
IP67 Waterproof & Dustproof Sealing
Fully sealed construction resists rain, dust, and accidental water immersion, making it ideal for outdoor cameras, perimeter alarms, and roadside security devices. PCB-mount models feature gaskets to maintain sealing when integrated into camera housings.
360° EMI Shielding for HD Video
Nickel-plated brass shell provides full electromagnetic interference (EMI) protection, ensuring distortion-free transmission of 4K/8K video signals from IP cameras to recording systems. Shielded PCB contacts further reduce signal noise in compact camera designs.
Secure Screw-Locking Mechanism
Vibration-proof screw lock prevents accidental disconnection from wind, vehicle vibration, or tampering, ensuring reliability in high-risk locations. PCB-mounted receptacles stay firmly anchored to internal boards, even in heavy vibration.
Wide Temperature Resilience
Operates from -40°C to +85°C, maintaining stable connectivity in extreme winter cold and summer heat for year-round security coverage. PCB-grade components are rated for thermal cycling to avoid solder joint fatigue.
Tamper-Resistant & Durable
Rugged metal housing resists physical damage and corrosion, with a lifespan of 500+ mating cycles to reduce maintenance and replacement costs. PCB-mount versions use high-temperature insulation to withstand soldering and long-term operation.
Versatile Configuration Options for M12 Connectors
1. Multiple M12 Coded Types Available
Choose the right type for your security device:
A-Code: 3-8 pins, ideal for analog cameras, power supplies, and basic alarm sensors. PCB-mount versions support direct integration into camera control boards.
D-Code: 4 pins, supports Gigabit Ethernet for IP cameras and PoE (Power over Ethernet) applications. PCB receptacles enable seamless board-to-cable connectivity in PoE-enabled cameras.
X-Code: 8 pins, for 10G Ethernet and high-bandwidth security systems like 8K cameras. PCB models deliver high-speed data without signal loss.
B-Code: 5-12 pins, for multi-signal transmission in PTZ cameras and access control systems. PCB-mount options simplify the integration of pan/tilt control signals.
S-Code: 4 pins, designed for high-power connections in thermal imaging cameras and outdoor lighting. PCB receptacles handle up to 16A for power-hungry devices.
2. Flexible Pin Count Configurations
3-4 pins: Power-only or PoE for IP cameras and access control readers. PCB versions support compact board layouts.
5-8 pins: PoE + data + control signals for PTZ dome cameras and multi-sensor systems. PCB models consolidate multiple signals on a single connector.
12 pins: Multi-channel data and power for advanced security sensors and alarm networks. PCB receptacles enable dense signal routing on control boards.
3. Mounting & Termination Options
PCB Mount Receptacles: Surface-mount (SMT) and through-hole (THT) designs for direct integration into camera PCBs, NVR boards, and access control controllers.
Panel-Mount Receptacles: Front-panel and rear-panel mounting options for camera housings and security enclosures, with locking nuts for secure installation.
Cable-Mount Plugs: Field-terminable or pre-wired options for connecting cameras to network cables and power supplies.
Ideal Security & CCTV Applications
Outdoor IP cameras, PTZ dome cameras, and thermal imaging cameras (PCB-mount for internal connectivity)
Perimeter intrusion detection systems and alarm sensors (panel-mount for enclosure integration)
Access control readers and intercom systems (PCB receptacles for board-level connections)
Mobile security vehicles and temporary surveillance setups (cable-mount for quick deployment)
Industrial security cameras and hazardous-area monitoring devices (heavy-duty PCB and panel mounts)
