Hirose Electric Circular Connector Series | High-Reliability Push-Pull Locking Connectors for Electronics/Instrumentation/Video Processing/Medical Equipment

🚀 Product Overview

As a globally leading connector manufacturer since 1937, Hirose Electric is committed to providing high-quality, technologically advanced connection solutions for the electronics industry. Our circular connector series features compact design, high reliability, and excellent operability, widely used in electronic devices, precision instrumentation, video processing systems, and medical equipment — fields with demanding performance requirements.

Hirose circular connectors utilize an innovative push-pull self-locking mechanism, requiring only a simple push to lock and a pull on the sleeve to unlock, offering easy operation with secure connections. The product line ranges from the ultra-compact HR10 series to the high-density HR25 series, meeting diverse application requirements across different scenarios.

✨ Core Highlights

1. Innovative Push-Pull Locking Mechanism

Enables quick connect/disconnect and blind mating, locks without rotation, supporting high-density installation. The unique guide key design ensures accurate insertion even in blind-mating situations, preventing pin damage. A clear tactile "click" feedback confirms secure locking.

2. High-Reliability Electrical Performance

Gold-plated copper alloy contacts ensure low contact resistance (≤5mΩ) and high signal fidelity, with mechanical life exceeding 1000 mating cycles. Precision insulator design effectively prevents signal crosstalk between adjacent pins, ensuring data transmission integrity.

3. Compact and High-Density Design

The smallest product diameter is only φ10mm (approximately the thickness of a cigarette), significantly saving equipment panel space. Available in configurations from 4 to 20 cores, meeting connection requirements from simple signal transmission to complex multi-channel data.

4. Superior Environmental Adaptability

Select series (such as HR30) feature IP67/IP68 waterproof ratings, completely dust-tight and suitable for long-term immersion, ideal for outdoor and harsh industrial environments. Wide operating temperature range (-25℃ to +85℃), resistant to vibration and shock.

5. High-Speed Transmission Capability

Supports Cat.5e (1Gbps) high-speed Ethernet transmission, meeting the high-speed data transmission requirements of 4K/8K ultra-high-definition video. Select series feature metal housing shielding design, effectively preventing electromagnetic interference (EMI) and ensuring signal integrity.

6. Medical-Grade Quality Assurance

Complies with medical electrical equipment safety standards; housing materials resist common medical disinfectants, suitable for high-reliability medical scenarios such as patient monitors, endoscopes, and surgical robots. Select series are certified to international quality standards including ISO9001 and ISO14001.

🏭 Detailed Application Areas

Electronic Devices

Hirose connectors are widely used in portable electronic devices, consumer electronics, and office automation equipment. Their compact size and lightweight design (e.g., HR30 series 6-position type weighs only 6 grams) make them ideal for space-constrained devices.

Instrumentation

In test and measurement instruments, precision analytical equipment, and laboratory instruments, Hirose connectors ensure measurement data accuracy and stability through high-reliability electrical performance and excellent anti-interference capability. Mechanical life exceeding 1000 cycles ensures long-term reliability.

Video Processing

For 4K/8K ultra-high-definition video transmission requirements, Hirose provides complete solutions:

• Broadcast Cameras: 12G-SDI compatible connectors supporting high-speed data transmission, lightweight design reduces overall equipment weight

• Machine Vision Cameras: ix Industrial™ connectors are smaller than RJ45, support Cat.6A high-speed transmission, high durability for frequent mating cycles

• Medical Displays: High-speed interface connections for medical imaging equipment such as endoscope displays

• Security Monitoring: Supports high-speed transmission of 4K video data, suitable for long-term outdoor use

Medical Equipment

Hirose connectors excel particularly in medical applications:

• Endoscope Systems: In endoscope light source modules, products maintain stable insulation resistance through high-temperature steam sterilization cycles, with lifespan far exceeding traditional aviation connectors

• Patient Monitors: Signal acquisition interfaces for multi-parameter monitors, ensuring high-fidelity transmission of weak bioelectrical signals such as ECG and SpO2

• Surgical Robots: Control and feedback connections for surgical robotic arms; keying variation functionality supports mixed insertion of multiple devices, reducing cable management costs

• Medical Imaging Equipment: Image data transmission for C-arms, portable ultrasound devices, and more
