SCONDAR SCT1200T Crimp Terminal: Precision-Engineered for 1.2mm Pitch Low-Profile Wire-to-Board Connectors
When designing ultra-compact electronic devices, every component must balance miniaturization with electrical integrity. The SCONDAR SCT1200T crimp terminal meets this challenge head-on. Designed for use in 1.2mm pitch, 1.4 mm height, and 4.3 mm width wire-to-board connector systems, the SCT1200T is form-fit-function compatible with ACH S-Series terminals (used in ACHR-xxV-A-S housings) while incorporating independent contact geometry that avoids infringing on existing patents.
Reliable Electrical Performance
The SCT1200T delivers consistent, low-resistance connections suitable for signal and low-power applications across consumer, industrial, and automotive interior environments.
| Parameter | Rating |
|---|---|
| Current Rating | 2A AC/DC |
| Voltage Rating | 50V AC/DC |
| Insulation Resistance | 100 MΩ (Min.) |
| Contact Resistance | 20 mΩ (Max.) |
| Withstanding Voltage | 500V AC (Min.) |
| Operating Temperature | -25°C to +85°C |
These specifications ensure stable performance in demanding conditions, from portable electronics to LED lighting modules and compact control boards.
Precision-Stamped for Small-Gauge Wires
The SCT1200T is specifically engineered to terminate small-diameter wires, a critical requirement for high-density interconnects:
| Parameter | Detail |
|---|---|
| Applicable Wire Sizes | 28 AWG to 32 AWG |
| Material | Phosphor Bronze, thickness 0.12 mm |
| Finish Options | Tin-plated or Gold-plated |
| Mating Pitch | 1.2 mm |
This narrow wire range allows for precise crimp force control, minimizing wire breakage while ensuring gas-tight connections.
Material Excellence: Phosphor Bronze
The SCT1200T is stamped from Phosphor Bronze (0.12 mm thick), a copper alloy known for:
High fatigue resistance – essential for repeated insertion cycles
Excellent spring properties – maintains normal force over time
Good corrosion resistance – reliable in humid or mildly aggressive environments
This material choice ensures the terminal retains its elastic characteristics even after multiple mating/unmating cycles.
Plating Options for Specific Applications
SCONDAR offers two plating variants to suit different cost and reliability requirements:
| Plating | Key Attributes | Recommended Applications |
|---|---|---|
| Tin-plated | Cost-effective, good solderability | Consumer electronics, general-purpose devices |
| Gold-plated | Superior corrosion resistance, lower contact resistance | Medical devices, industrial controls, high-reliability systems |
Both finishes meet industry standards for thickness and adhesion, ensuring consistent crimping and mating performance.
Compatible Housing & System Integration
The SCT1200T is designed to be mechanically compatible with SCONDAR SCT1200H housing (Nylon 66, UL94V-0) as well as existing 1.2 mm pitch ACH-type receptacles, including the widely used JST ACHR-xxV-A-S series (e.g., ACHR-02V-A-S, ACHR-04V-A-S, ACHR-06V-A-S).
However, the SCT1200T incorporates proprietary contact beam geometry and retention lance design that differ from protected features of any existing brand. This ensures:
Drop-in replacement functionality for existing ACH S-Series terminal footprints
No replication of patented JST terminal structures (e.g., specific box contact designs or lance configurations)
Full compliance with global intellectual property regulations when mated with SCONDAR’s complete connector system
Important: For assured performance and legal compliance, SCONDAR recommends using the SCT1200T exclusively with SCONDAR SCT1200H housings or headers. While physical compatibility with third-party housings may exist, users are responsible for validating patent status in their jurisdiction.
Crimping Recommendations
To achieve optimal electrical and mechanical performance:
| Parameter | Recommendation |
|---|---|
| Crimp Tool | SCONDAR SCT-CrimpTool-1200 (or generic micro-termination tools with appropriate anvils) |
| Strip Length | 1.5 mm – 1.8 mm (conductor only, no insulation in contact area) |
| Crimp Height | 0.55 mm – 0.65 mm (depending on wire gauge) |
| Pull-out Force | ≥ 15 N (for 28 AWG) |
Proper crimp tooling and setup are essential to achieve the stated 20 mΩ maximum contact resistance.
Applications
The SCT1200T is ideal for:
Ultra-compact wearables and hearables
Small drone/vibration motors
LED strip lighting interconnects
Battery management system (BMS) signal lines
Miniature sensor modules
Space-constrained PCBs in IoT devices
