Description
70504-C-50 is a fixed-mount PCB barrier terminal strip from the Molex 38700 series, designed for secure wire-to-board connections in power and control applications. It features a screw clamp with washer structure, ensuring reliable mechanical and electrical contact for medium power levels.
Features
- Pitch: 8.26 mm (0.325 inch)
- Screw clamp with washer for strong wire retention
- Barrier-style design for improved electrical isolation
- Through-hole PCB mounting
- High current handling capability
- Durable thermoplastic housing (black)
Electrical Specifications
- Current rating: 20 A
- Voltage rating: 300 V
- Suitable for medium power distribution and control circuits
Mechanical Characteristics
- Mounting type: Through-hole PCB
- Wire termination: Screw clamp with pressure plate (washer)
- Pitch spacing: 8.26 mm → supports thicker wires and higher creepage distance
- Component type: One-piece barrier strip
Material Information
- Housing: High-strength thermoplastic (UL-rated)
- Contacts: Metal alloy with plating for corrosion resistance
- Screws: Steel with plating for durability
Functional Description
- Provides a secure interface between external wires and PCB traces
- Barrier walls between პოზitions reduce risk of short circuits
- Screw clamp ensures stable connection under vibration and thermal cycling
Design Notes
- Ensure proper PCB hole size and pad design for current handling
- Use appropriate wire gauge to match 20A rating
- Apply correct torque to screws to avoid संपर्क failure or damage
- Maintain creepage/clearance distances for 300V operation
- Consider vibration environment → screw locking may be required
How to Choose This Terminal Block
- Select based on current (20A) and voltage (300V) requirements
- Choose pitch according to insulation and wiring needs
- Barrier type preferred for safety-critical or high-voltage designs
- Verify compatibility with PCB layout and enclosure constraints
Typical Applications
- Industrial control panels
- Power supply distribution boards
- HVAC systems
- Machinery and automation equipment
- Appliances and power electronics interfaces
