Long Form Middle Bare Connector

1. Key Parameters in Model Naming

The models of long-form middle bare connectors are primarily distinguished by the following parameters:

Conductor Cross-Section Area (Core Differentiator)

• Model Examples: LFMB-0.5 (0.5mm²), LFMB-2.5 (2.5mm²), LFMB-6 (6mm²)
• Note: Larger numbers indicate higher current-carrying capacity. Some brands use letter codes (e.g., A=0.5mm², B=1mm²); consult catalogs for exact mappings.

Rated Current and Voltage

• Model Examples: LFMC-10-250AC (10A/250V AC), LFMC-30-660VDC (30A/660V DC)
• Note: Prefixes/suffixes denote voltage types (AC/DC) and ratings.

Connection Type

• Spring Clamp: LFMS-XX (e.g., LFMS-4)
• Screw Terminal: LFSB-XX (e.g., LFSB-6)
• Plug-and-Pull Interface: LFPL-XX (e.g., LFPL-10)

(Optional)

• IP-Protected: LFMP-IP67-XX (dust/waterproof for harsh environments)
• Standard: LFMA-XX (basic insulation only)

2. How to Distinguish Models

Identify Conductor Cross-Section

• Read the numeric value directly (e.g., LFMB-6 = 6mm²) or use brand-specific coding tables.

Determine Connection Method

• Spring Clamp: Look for S or CLAMP in the model name (e.g., Spring Clamp Terminal).
• Screw Terminal: Check for B or SREW (e.g., Screw Terminal).
• Plug-and-Pull: Search for P or PLUG (e.g., Plug-and-Pull Terminal).

Check

• Models with IP (e.g., IP67) indicate dust/water resistance; standard models lack this suffix.

Material/Process Markings

• Tin/Nickel Plating: Often marked SN (e.g., LFMB-6-SN).
• Oxidation Resistance: High-end models may specify Oxidation Resistant.

4. Selection Guidelines

Choose Based on Load

• Light Loads (signal lines): 0.5–2.5mm²
• Heavy Loads (power cables): 6–10mm²

Match Environmental Conditions

• Dry Environments: Standard models
• Humid/Vibratory Environments: IP-protected or reinforced screw terminals

Prioritize Connection Needs

• Frequent plug/unplug cycles: Use plug-and-pull types (e.g., LFPL series).
• Permanent installations: Opt for screw terminals (e.g., LFSB series).

5. Important Notes

• Model naming conventions vary by brand; always refer to manufacturer catalogs.
• If exact model parameters are unavailable, measure terminal dimensions (e.g., thread) or contact suppliers for compatibility verification.
