1960660

Overview

Phoenix Contact part number 1960660 is a fixed terminal block from the MC series, specifically the MC 1,5/20-STF-3,81 AU model. It features a nominal cross-section of 1.5 mm² and accommodates 20 positions in a single row with a 3.81 mm pitch. The unit utilizes screw connection methods and gold-plated contact surfaces. Rated voltage is 160 V (III/2) with a nominal current of 8 A. The housing is green, designed for printed circuit board mounting.

Feature Summary

• Gold-plated contact surfaces ensure reliable electrical conductivity
• Screw connection method provides secure wire termination
• Single-row configuration supports 20 potentials

Applications

• Printed circuit board interconnections
• Industrial control panel wiring
• Signal distribution modules

Procurement Notes

Verify the specific suffix 'AU' indicates gold plating when sourcing. Confirm the 3.81 mm pitch matches the PCB footprint requirements. Ensure the 160 V rating aligns with the system's surge voltage category III specifications. Cross-reference the 8 A nominal current against the actual load conditions to prevent thermal issues.

Selection Notes

Select this component for applications requiring high corrosion resistance due to gold contacts. The 3.81 mm pitch offers a balance between density and safety clearance. Verify compatibility with standard screwdrivers for the screw connection type. Consider the green color coding if it fits the existing visual identification scheme.

Part Context

This component belongs to the Phoenix Contact MC series of fixed terminal blocks. These are widely used in automation and industrial electronics for reliable signal and power distribution on PCBs. The series is known for compact design and robust mechanical stability under vibration.

Replacement Considerations

Check for identical pitch and pin count in alternative brands. Ensure voltage and current ratings meet or exceed original specifications. Verify physical dimensions for enclosure fit. Confirm contact material compatibility if environmental conditions differ.
