SY Series Circular Connectors for Portable Measurement Equipment

M12 Circular Connectors

Application Background

In Japan, portable measurement equipment is widely deployed for field testing, maintenance, and inspection tasks across industrial and outdoor environments. These devices demand compact, dependable connections that support both power delivery and signal transmission while withstanding the rigors of on-site handling.

Connector Application

SY series circular connectors, including models such as SY17 and SY21, are integrated into portable instrumentation for several critical functions:

• Power input connections for reliable operation in the field
• Signal interfaces between internal modules to maintain data integrity
• External cable connections for sensors and probes, ensuring secure mating

Design Characteristics

The SY series employs a bayonet locking mechanism, enabling rapid connection and disconnection without tools—an essential feature for technicians working in time-sensitive measurement tasks. These connectors provide IP67 sealing, protecting internal circuits from dust and temporary water immersion. Multiple pin configurations are available to match the specific power and signal requirements of different portable devices.

Operational Environment

Portable measurement equipment is frequently deployed in demanding settings, including outdoor sites and industrial plants. The connectors must endure continuous handling, mechanical vibration, and exposure to moisture or contaminants. The SY series is designed to maintain stable electrical performance under these conditions, reducing the risk of connection failure during critical measurements.

Conclusion

SY series circular connectors offer a reliable and flexible interconnection solution for power and signal circuits in portable measurement equipment. Their quick-locking design, environmental sealing, and adaptable pin configurations make them a practical choice for engineers seeking durable connectivity in field-based instrumentation.
