Vertical Overmolded Type:
180° Vertical Straight Design The connector and cable form a 180° straight-line connection without bending angles, suitable for installation scenarios requiring vertical cable exit from equipment panels or linear cable arrangement. This design reduces cable stress concentration and prevents core wire breakage or signal interference caused by bending. Low-Loss Transmission Contacts adopt a brass gold-plating process (gold plating thickness ≥ 3μm). Contact resistance ≤ 5mΩ, insulation resistance ≥ 100MΩ. These specifications ensure the stability of power and signal transmission, meeting the communication requirements of harsh industrial bus systems. High Protection Rating Complies with IP67 protection standard, which enables the connector to withstand immersion in 1-meter deep water for 30 minutes and supports long-term underwater operation. It effectively blocks the intrusion of oil, dust, and moisture.

Safety Warning
 

The connector must not be plugged or unplugged under load. Failure to follow the instructions and improper use can result in personal injury. 

The development of the connector is aimed at being applied in factory engineering, control and electrical equipment construction. Users are responsible for checking whether the connector can also be used in other applications. 

Connectors used in circuits with dangerous voltages that cause electric shock must be installed and used only by personnel who have received training in electrical engineering, or under their supervision, while taking into account the applicable regulations and standards.


Users must take appropriate security measures to ensure that the connectors do not accidentally disconnect. 

When installing, apply moderate force and use the special tool to tighten the nuts. Avoid excessive force to prevent the shell from deforming or the pins from bending. Ensure that the plug and socket are fully engaged. Do not power on the device when not locked in place to prevent arc discharge due to poor contact. 

The plug connectors with an enclosure protection rating of IP67 and IP68 are not suitable for use in water. When used outdoors, the plug connectors must be protected against corrosion separately. For further information on IP protection ratings, please refer to "Technical Information".
