In demanding industrial settings where moisture, dust, and even potential flooding pose constant threats to equipment reliability, the failure of a single connector can bring entire production lines to a standstill. Amphenol LTW addresses this critical challenge with its IP68-rated waterproof circular connectors, delivering reliable connectivity in the most challenging conditions.

The Amphenol LTW circular connector series combines exceptional waterproof performance (IP68 rating) with rugged construction, making it an ideal choice for industrial applications. The product line offers multiple configurations including socket type, cable socket type, molded cable type, and field-installable versions to accommodate diverse application requirements.

Available in five size categories from miniature to macro (mini, standard, medium, large, and macro), these connectors ensure optimal solutions for various spatial constraints. The series features three distinct connection methods—bayonet, threaded, and push-lock—enhancing both flexibility and ease of use.

The IP68 rating certifies that these connectors can operate continuously underwater at specified depths (typically 1.5 meters), effectively preventing water and dust ingress to maintain reliable connections.

• Bayonet: Enables quick connection and disconnection for applications requiring frequent mating cycles.
• Threaded: Provides secure locking for vibration-prone environments.
• Push-lock: Simplifies operation with one-handed connection capability.

• Mini: Designed for space-constrained applications like compact sensors and instruments.
• Standard: General-purpose connector suitable for diverse industrial uses.
• Medium: Supports higher current capacity for power-intensive equipment.
• Large: Accommodates substantial data or power transmission requirements.
• Macro: Heavy-duty solution for industrial machinery and high-power applications.

• Socket type: Panel-mounted solution for fixed connection points.
• Cable socket type: Pre-assembled cables simplify installation.
• Molded cable type: Integrated cable-connector design enhances waterproofing.
• Field-installable: Enables on-site cable termination for maximum adaptability.

Beyond their robust design, Amphenol LTW waterproof circular connectors deliver exceptional performance metrics to ensure reliable operation in extreme conditions:

• Current/Data Capacity: Multiple current ratings including 2A, 5A, 10A, 20A and hybrid configurations (5A+2A, 10A+5A, 20A+2A, 20A+5A)
• Operating Temperature: -20°C to +105°C range
• Contact Resistance: ≤10mΩ
• Insulation Resistance: ≥100MΩ at DC500V
• Mating Cycles: Minimum 1,000 insertions
• Voltage Withstand: AC 1000V/1 minute
• Salt Spray Resistance: 48-hour test certified
• Cable Lengths: 0.1m to 99m standard options

These connectors serve critical functions across multiple industries:

• Industrial Automation: Sensor, actuator, and motor drive connectivity
• Outdoor Lighting: Street, architectural, and landscape lighting systems
• Renewable Energy: Solar panels, wind turbines, and charging stations
• Rail Transportation: Train control, signaling, and lighting systems
• Marine Engineering: Underwater sensors and robotic systems
• Defense Systems: Military communications and radar equipment

When specifying Amphenol LTW waterproof connectors, consider these critical factors:

1. Environmental Conditions: Assess temperature, humidity, and chemical exposure
2. Electrical Requirements: Verify current/voltage specifications
3. Signal Characteristics: Determine analog/digital/power signal needs
4. Connection Method: Select bayonet, threaded, or push-lock based on application
5. Physical Constraints: Choose appropriate size and configuration
