Visual Inspection System Trigger Cable Requirements

Trigger cables in visual inspection systems must meet specific electrical and mechanical requirements to ensure reliable image capture in automated production environments .

Electrical Requirements:

• Trigger Signal Integrity: Steep signal edges for precise timing

• Power Delivery: 12-24V DC with minimal voltage drop

• EMC Shielding: Dual shielding to reduce interference in industrial environments

• Contact Resistance: ≤5 mΩ to maintain signal quality

• Insulation Resistance: ≥1000 MΩ to prevent leakage

Mechanical Requirements:

• Flex Life: Up to 50 million cycles for continuous motion applications

• Abrasion Resistance: PUR jacket for drag chain and moving equipment

• Environmental Sealing: IP67 for dust and water resistance

• Small Diameter: Down to 3 mm for confined spaces

The combination of these electrical and mechanical requirements ensures reliable trigger signal transmission in demanding manufacturing environments .
