LD Series IP67 Waterproof Connector for Crane Load Moment Limiters

For outdoor crane load moment limiters, the connection point must reliably transmit weight and angle signals while enduring rain, dust, vibration, and temperature swings. The LD series waterproof connector (IP67) is engineered for this duty, with an operating temperature range of -40°C to 85°C suited to outdoor high and low temperature environments.

Key Specifications and Benefits

• 4-pin configuration: Dedicated contacts for transmitting weight and angle signals from the limiter.
• Snap-lock design: Enables tool-free, quick installation and secure mating in the field.
• IP67 protection: Sealed against dust ingress and temporary water immersion, supporting reliable outdoor operation.
• Salt spray resistance (≥500h): Suitable for humid, corrosive environments such as ports, docks, and coastal sites.

Application Fit and Reliability

This connector is designed to prevent signal interruption in the load moment limiter, which could otherwise lead to undetected overload conditions. Its robust housing and sealed contacts help maintain stable performance in demanding outdoor applications, supporting operational safety for crane lifting duties.
