GOST Standard P Series Circular Connectors for Smart Home Systems

OHS Circular Connector

Full Core Size Specifications (GOST Compliant)

The P Series covers all standard shell sizes, optimized for different power and signal density needs:

• P16: 16mm outer diameter, 2-8 pins. Ideal for compact control modules and low-power sensors.
• P20: 20mm outer diameter, 2-12 pins. The most versatile size for mid-range smart home devices.
• P28: 28mm outer diameter, 4-20 pins. For power+signal hybrid applications like floor heating controllers.
• P32: 32mm outer diameter, 6-24 pins. Designed for high-density multi-system integration in distribution boxes.
• P44/P48/P55: 44-55mm outer diameter, 8-35 pins. For heavy-duty power distribution and industrial-grade smart home hubs.
• P60: 60mm outer diameter, 10-40 pins. The largest size for ultra-high-power, high-density smart home core systems, supporting single-pin current up to 35A.

Flexible Multi-Pin Configurations

Each shell size offers a wide range of pin options to match smart home transmission requirements:

• 2-4 pins: Basic power supply for devices like smart locks, curtain motors, and small sensors.
• 6-12 pins: Combined power and control signal transmission for floor heating systems, ventilation units, and outdoor cameras.
• 16-35 pins: Multi-system integration for whole-home distribution boxes, central control panels, and energy storage inverters.
• 10-40 pins (P60 exclusive): Ultra-high-density integration for villa-grade smart home main control cabinets, large-scale energy storage systems, and multi-device hybrid power-signal transmission.

Core Performance Advantages (GOST Compliant)

1. Vibration-Proof Threaded Locking

The precision threaded coupling ensures a secure, anti-loosening connection, preventing accidental disconnection in high-vibration environments such as curtain motors and outdoor equipment.

2. Heavy-Duty Multi-Core Design

Supports 2-40 pins and contact diameters from 1.5mm to 6.0mm, enabling simultaneous transmission of power, control signals, and data for complex whole-home smart systems. The P60's 6.0mm contact pins meet the high-current demand of large energy storage and power distribution equipment.

3. Industrial-Grade Durability

Constructed from zinc alloy and stainless steel, with gold-plated contacts (≤1 mΩ contact resistance), the P Series delivers a lifespan of 5,000+ mating cycles, ensuring long-term reliability in heavy-duty applications. The P60's reinforced shell structure resists mechanical impact and compression, suitable for long-term fixed installation.

4. Flexible Termination Options

Compatible with solder, crimp, and screw terminals, allowing seamless integration into diverse smart home installations, from compact control modules to high-power distribution boxes. The P60 supports large-gauge cable connection, meeting the wiring needs of high-current devices.

Smart Home Application Scenarios

The P Series adapts to diverse smart home environments, with size and performance characteristics matched to specific use cases:

• Whole-House Distribution Boxes: P32/P44 models with 16-35 pins integrate power, lighting control, and security signals into a single connection, simplifying wiring and maintenance.
• High-Power Devices: P28/P32 variants with 8-20 pins deliver stable power and feedback signals for floor heating controllers, whole-home ventilation systems, and energy storage inverters.
• Outdoor Smart Devices: ZP/CwP sealed models provide waterproof, dustproof connectivity for garden irrigation systems, outdoor security cameras, and photovoltaic panels.
• Control Modules & Sensors: P16/P20 sizes with 2-8 pins connect smart sensors (temperature, motion, door/window) and compact control panels, ensuring anti-vibration reliability.
• Villa-Grade Core Control Systems: P60 sealed/unsealed models with 10-40 pins serve as the central connection hub for large smart villas, integrating multi-channel high-power supply, audio-visual signals, security monitoring, and energy storage management systems; ZP60 sealed versions are also suitable for outdoor large equipment like intelligent electric gates and large sunshade systems.

Selection and Integration Guidance

When selecting a P Series connector for your project, consider the following decision points:

• Pin count and contact diameter: Match the number of cores and contact size to your power and signal requirements. Refer to the Technical Specifications for exact values.
• Shell size: Choose the outer diameter that fits your device's mounting space and cable entry requirements.
• Termination method: Select solder, crimp, or screw termination based on your assembly process and field-service needs.
• Environmental protection: For outdoor or wet locations, specify sealed ZP/CwP variants; for indoor dry environments, standard unsealed models may suffice.
