5.08mm Pitch Pluggable Terminal Block System
The 5.08mm Pitch Pluggable Terminal Block System provides a reliable, efficient, and maintenance-friendly wire-to-board connection for industrial electronics, automation systems, and power supplies.
Designed with a high-performance rising clamp (screw cage) mechanism, this connector ensures maximum contact force and vibration resistance, preventing wire damage from repetitive clamping. The pluggable design allows for quick hot-swapping and field wiring without desoldering.
Complete System Components Included:
Pluggable Female Plug: Features secure M2.5 screw cage termination.
Right-Angle PCB Header (XK2EDGR / XK2EDGRC): Available in standard open ends or shrouded/closed ends for polarization and anti-misinsertion.
Vertical/Straight PCB Header (XK2EDGV / XK2EDGVC): Ideal for space-constrained vertical board-to-wire layouts.

FAQ: 5.08mm Pluggable Terminal Blocks
Q1: What is the difference between a rising clamp and a standard leaf-spring terminal block?
A: A rising clamp (screw cage) design utilizes a solid metal elevator mechanism that rises and compresses the wire uniformly against the contact bus bar as the screw is tightened. This provides a gas-tight, high-torque connection that protects fine wire strands from being twisted or damaged by the screw. Standard leaf-spring types simply press a thin metal leaf directly onto the wire with the screw, which offers lower clamping force and is less reliable in high-vibration industrial environments.
Q2: What are the mating options available for these pluggable connectors?
A: This pluggable female connector is designed to pair perfectly with standard 5.08mm pitch male pin headers. Depending on your PCB layout and space constraints, you can choose from:
Right-Angle/Horizontal Headers (XK2EDGR / XK2EDGRC series): Ideal for edge-of-board or side-entry configurations.
Straight/Vertical Headers (XK2EDGV / XK2EDGVC series): Best for space-restricted, vertical top-entry wiring.
Note: Both styles are available in shrouded/closed-end versions to provide alignment polarization and prevent incorrect plugging.
Q3: What is the maximum wire size and electrical capacity this terminal block can handle?
A: * Wire Gauge Range: It accepts solid or stranded wires from 24 AWG down to 12 AWG (up to cross-sectional areas of 2.5mm².
Electrical Ratings: It is rated for a maximum voltage of 300V and a maximum current of 10A.
Dielectric Strength: It features a withstanding voltage of 1600V AC for 1 minute and a rated impulse voltage of 4.0 KV, ensuring excellent surge protection.
Q4: Are these terminal blocks suitable for harsh or high-temperature industrial environments?
A: Yes, absolutely. The insulation housing is made of premium PA66 (UL94V-0), which is highly flame-retardant and maintains mechanical integrity over a wide operating temperature range of –40℃ to +105℃. Additionally, the phosphor bronze contacts are nickel-plated to prevent oxidation and ensure long-term, low-resistance connectivity in humid or corrosive industrial environments.
Q5: What are the recommended torque and stripping specifications for installation?
A: For optimal performance and safety, please adhere to the following installation guidelines:
Wire Stripping Length: Strip the wire insulation back by 7 to 8 mm before insertion.
Screw Size & Tightening Torque: The terminal uses M2.5 steel screws. The recommended tightening torque is 0.4 N.m (3.5lb-in) to ensure a secure clamp without over-tightening.
Q6: Can I order specific pin configurations, such as 3-pin or 5-pin variants?
A: Yes. While the engineering drawings display standard configurations, this product line is fully scalable and modular, available in any position from 2 Poles up to 24 Poles (2P – 24P) to match your specific PCB layout requirements.
