Product Details

SAK Series Core Architecture: Precision Engineering for Secure Connections

Flame-Retardant Insulation Housing: Crafted from high-quality flame-retardant nylon or PA66 engineering plastics. It provides robust support for internal components and superior electrical insulation for maximum safety.

High-Conductivity Metal Components: The core conductive path is manufactured from high-purity copper or tin-plated copper, ensuring low resistance and highly efficient current transmission.

Frame-Type Screw Clamp Mechanism: A signature feature of the SAK series. The crimping frame ensures uniform pressure distribution when tightened, locking wires securely in place for a vibration-proof connection.

Precision Screw & Pressure Plate System: Designed to convert torque into powerful vertical clamping force, ensuring a tight, stable electrical contact between the wire and the conductor.

Standard Rail Mounting Interface: Equipped with specialized mounting feet and clips for perfect compatibility with TH35/NS35 DIN rails, enabling rapid snap-on installation to boost assembly efficiency.

How to Wire SAK Terminal Blocks: A Step-by-Step Guide

SAK terminal blocks typically utilize a robust screw-clamp connection system. To ensure a safe and secure electrical connection, please follow these standard operating procedures (as illustrated in your image):

  1. Strip the Wire: Carefully strip the insulation from the end of the wire to expose the copper conductor. Ensure the exposed length is appropriate for the terminal block depth without damaging the strands.
  2. Insert the Conductor: Fully insert the stripped wire into the terminal block’s wire entry hole until it reaches the internal stop, ensuring optimal positioning.
  3. Tighten the Clamp: Using a screwdriver, rotate the clamping mechanism to apply the necessary torque. This drives the internal pressure plate to securely fasten the wire, creating a gas-tight, low-resistance connection.
  4. Verify Connection: Gently tug on the wire to confirm it is firmly locked in place with no movement. Once verified, remove the tool to complete the installation.

Step-by-Step Guide to SAK Terminal Blocks: 4 Steps to Fast & Secure Connections

Achieve professional-grade wiring with speed and confidence. The SAK series is designed for efficiency, allowing you to complete reliable connections in just four simple steps:

  1. Efficient Preparation: Strip the wire insulation and insert it into the terminal block. This tool-free insertion design saves valuable time on every connection, boosting your overall assembly efficiency.
  2. Easy Access: Simply use a screwdriver to press down the clamp mechanism, instantly opening the wire channel for smooth and obstruction-free installation.
  3. Secure Insertion: Push the wire fully into the chamber until it seats correctly. This ensures maximum surface contact for optimal conductivity and a stable electrical link.
  4. Reliable Locking: Tighten the clamp to firmly secure the conductor. This creates a robust, vibration-resistant connection that guarantees long-term safety and durability.

How to Maintain Terminal Blocks

 

Regular Inspection

  • Regularly inspect terminal blocks for signs of wear, corrosion, or loose connections.

Clean Terminal Blocks Regularly

  • Use a soft brush and compressed air to clean terminal blocks and remove any dirt, dust, or debris that may accumulate on the contact points.

If Any Loose Connection Is Found

  • If any connection becomes loose, use a screwdriver to tighten the screws to the manufacturer’s recommended torque value. This helps ensure a safe and reliable electrical connection.

Check for Overheating

  • Inspect terminal blocks for signs of overheating, such as discoloration or deformation. Overheating may be caused by excessive current or poor contact resistance, and should be addressed promptly to prevent further damage.

Always Use Properly Sized Terminal Blocks

  • Be sure to select the correct size and type of terminal block according to the application requirements. Using undersized terminal blocks may lead to overheating, poor contact, and other issues.

Troubleshoot Faulty Connections

  • If a faulty connection occurs, check the wiring for short circuits, open circuits, or incorrect positioning. Use a multimeter or other diagnostic tools to identify the root cause of the problem.

Follow the Manufacturer’s Guidelines

  • Always follow the terminal block manufacturer’s instructions for installation, operation, and maintenance to ensure safe and reliable performance.
