DEFENDER GATE

DEFENDER GATE is a specialized line of dock safety sensors and gate locks designed for loading dock environments. The product family includes restraint sensors, leveler sensors, and gate locks that monitor trailer position, gate closure, and leveler status to help prevent accidents during loading and unloading operations. These devices are typically constructed from steel with a silver finish, and they incorporate magnetic reed switches or similar sensing technologies to provide reliable position feedback. The sensors are often supplied with mounting bracket assemblies and leads of various lengths, such as the 8 ft lead found on the NDG-RS model. Key specifications include overall widths ranging from 2 1/4 inches to 4 inches and overall lengths from 1 inch to 2 1/2 inches, depending on the model. The DEFENDER GATE product line is engineered to integrate with dock gates and levelers, offering a straightforward way to add monitoring and safety interlocks to existing dock equipment. 3G Electric supplies the DEFENDER GATE line as part of its broader industrial equipment catalog. The available SKUs include the NDG-RL restraint sensor and gate lock, the NDG-RS restraint sensor, and the NDG-LS leveler sensor. Each product is supported with datasheets and logistics coordination for global delivery. 3G Electric serves plant engineers, maintenance managers, and procurement specialists who require specific part numbers and technical specifications for dock safety upgrades or replacements. The DEFENDER GATE sensors are used in applications where detecting the presence or position of a trailer, gate, or leveler is critical for operational safety. By providing multiple SKUs and associated documentation, 3G Electric facilitates the selection and procurement of these components for industrial facilities worldwide.

  • Dock leveler position detection — DEFENDER GATE NDG-LS leveler sensor ensures safe gate operation during loading and unloading.
  • Industrial gate interlocking — DEFENDER GATE sensors integrate with gate controls to prevent operation when unsafe conditions exist.
  • Maintenance and replacement — DEFENDER GATE sensors provide drop-in replacements for existing dock safety systems.

Frequently asked questions

Common questions about DEFENDER GATE from 3G Electric.

What is the difference between the DEFENDER GATE NDG-RL and NDG-RS sensors?

The NDG-RL (SKU 799L02) is a restraint sensor and gate lock combination with a 4-inch overall width and 2 1/2-inch overall length, including a mounting bracket assembly. The NDG-RS (SKU 799KZ9) is a restraint sensor with a 1-inch overall length and 4-inch overall width, featuring a magnetic reed switch with an 8 ft lead. Both are steel with a silver finish, but the NDG-RL includes a gate lock function, while the NDG-RS focuses on restraint sensing.

What are the typical applications for DEFENDER GATE leveler sensors?

DEFENDER GATE leveler sensors, such as the NDG-LS (SKU 799L01), are used to detect the position of a dock leveler. This information helps ensure safe gate operation during loading and unloading by preventing the gate from opening or closing when the leveler is not in the correct position. They are commonly found in loading dock safety systems where interlocking with leveler status is required.

What materials and finishes are used in DEFENDER GATE dock gate sensors?

DEFENDER GATE dock gate sensors are constructed from steel and have a silver finish. This provides durability and corrosion resistance in typical loading dock environments. The sensors may include additional components such as magnetic reed switches and mounting bracket assemblies, depending on the model.

How does 3G Electric support the DEFENDER GATE product line?

3G Electric supplies DEFENDER GATE dock gate sensors as part of its industrial equipment catalog. We provide access to multiple SKUs, including the NDG-RL, NDG-RS, and NDG-LS, along with datasheets and technical specifications. Our logistics support enables global shipping, and we assist procurement specialists in identifying the correct part numbers for their dock safety applications.

What are the overall dimensions of the DEFENDER GATE NDG-LS sensor?

The DEFENDER GATE NDG-LS leveler sensor (SKU 799L01) has an overall length of 1 1/4 inches and an overall width of 2 1/4 inches. It is made of steel with a silver finish and includes a mounting bracket assembly. These dimensions allow it to be installed in space-constrained areas of a dock leveler.
