SP Welded Square Four-Hole Panel Mount

The SP Welded Square Four-Hole Panel Mount Series (SP17/SP21/SP29) adopts a four-corner symmetrical mounting design, offering stable and reliable welded connections. With an IP68 protection rating, it is resistant to vibration and shock, making it suitable for industrial applications such as heavy machinery and power systems. It supports various configurations from 2-35 cores.

The SP Welded Square Four-Hole Panel Mount Series includes three models: SP17, SP21, and SP29, specifically designed to provide high-strength fixed connection solutions for industrial equipment panels. This series utilizes a square four-hole mounting design, ensuring the reliability of electrical connections through welded terminations. It is particularly suitable for industrial environments with vibration and shock. The product size specifications are complete, meeting different levels of application needs: SP17 < SP21 < SP29.

Series Core Features:

Square Four-Hole Fixing Structure: Uses a square symmetrical four-hole mounting design, achieving secure panel fixation via four bolts, providing excellent anti-vibration, anti-torsion, and anti-impact capabilities.

High-Strength Mounting Method: Requires four symmetrical mounting holes in the panel; four-point mechanical fixation ensures connector stability under working conditions.

Effective Single-End Sealing Protection: Equipped with a silicone sealing ring, achieving an IP68 protection rating, reliably preventing liquids, dust, and contaminants from entering the equipment interior.

Permanent Fixed Design: Developed specifically for static installation scenarios; the position is completely fixed after installation, ensuring lasting stable electrical connection performance.

Complete Specification Sequence: SP17 supports 2-10 core applications; SP21 expands to 1-15 cores and various variant configurations; SP29 provides 2-35 cores and special model configurations.

Materials and Manufacturing Process:

Housing uses high-strength PA66/PA6 engineering plastic, possessing good mechanical strength and environmental resistance.

Contacts are made of gold-plated copper, ensuring conductivity and oxidation resistance.

Insulating material uses high-temperature resistant (200°C) reinforced nylon, ensuring electrical safety in high-temperature environments.

Environmental Adaptability:

Operating temperature range -25°C ~ 85°C, suitable for industrial environmental temperature requirements.

Mating cycle life exceeds 500 times, guaranteeing long-term use reliability.
