4. DESIGN FEATURES
Standard Features:
M4 Threaded Stud – Secure fastening for wire connections
0.7mm Wire Hole – Compatible with 22-24 AWG wires
1.6mm Thickness – Balances strength and weight
Optional Enhancements:
Tin/Gold Plating – Improved conductivity & corrosion resistance
Insulation Sleeves – PVC/heat-shrink options
Laser Marking – Part numbers or polarity indicators
5. QUALITY & TESTING
Dimensional Checks: Optical comparator (±0.01mm accuracy)
Electrical Testing: 4-wire resistance verification
Environmental: Salt spray testing per ASTM B117 (48+ hours)
Certifications: RoHS, REACH compliant
6. TYPICAL APPLICATIONS
PCB Terminal Blocks – Secure wire-to-board connections
Power Distribution – Busbar interfacing in compact spaces
Sensor Wiring – Vibration-resistant automotive/industrial links
7. ORDERING GUIDANCE
To Procure This Terminal:
