Frequently Asked Questions
What are the PCB layout and through-hole drilling requirements for this 2.54mm machined female socket?
The connector features a straight through-hole solder tail with a diameter of Ø0.60mm ±0.02mm and requires a recommended PCB plated through-hole (PTH) diameter of Ø1.00mm ±0.05mm on a standard 2.54mm pitch grid. The insulator body has a profile height of 4.20mm ±0.10mm and an overall height of 7.40mm ±0.15mm.
Why is a two-piece machined brass sleeve with a 6-finger beryllium copper clip preferred over stamped contacts?
A precision-machined CuZn38Pb2 brass outer sleeve paired with a heat-treated 6-finger beryllium copper inner contact provides multi-point wiping action and gas-tight electrical contact. It maintains a low maximum contact resistance of 10 mΩ, stable insertion (1.2N typ.) and withdrawal (0.6N typ.) forces, and reliable operation across 500 minimum mating cycles in high-vibration industrial environments.
What mating pin dimensions and current ratings does this 2.54mm socket strip support?
Each contact is rated for 3 Amps and 1000V RMS minimum dielectric strength. The 6-finger internal contact clip accommodates round or square mating pins with diameters ranging from 0.635mm to 0.889mm.
What thermal conditions can the PPS insulator withstand during PCB assembly and operation?
Molded from UL94V-0 black Polyphenylene Sulfide (PPS), the insulator supports a continuous operating temperature range from -40°C to +105°C and resists peak soldering temperatures up to +255°C without housing deformation.
Overview and Application Notes
The 2.54mm pitch machined female socket strip connector is engineered for high-reliability board-to-board and IC package interconnects. Featuring a straight through-hole (DIP) mounting configuration with a 4.20mm insulator profile height and 7.40mm overall mating height, this precision-turned socket incorporates a 6-finger heat-treated beryllium copper contact clip inside a machined brass sleeve. It ensures gas-tight electrical continuity and high shock/vibration resistance across industrial automation, embedded control modules, and instrumentation systems.
Key Features
- Precision 6-Finger Contact Clip: Stamped and formed heat-treated beryllium copper inner contact paired with a precision-machined brass (CuZn38Pb2) outer sleeve for consistent normal force and low contact resistance (10 mΩ Max.).
- High Current & Dielectric Performance: Rated at 3 Amps per contact with a minimum dielectric withstanding voltage of 1000V RMS for reliable power and signal routing.
- High-Temperature PPS Insulator: Molded from black Polyphenylene Sulfide (PPS) rated UL94V-0, capable of withstanding wave and selective soldering temperatures up to +255°C and operating across -40°C to +105°C.
- Wide Mating Pin Compatibility: Accepts round or square mating leads ranging from 0.635mm to 0.889mm in diameter, offering smooth 1.2N typical insertion force and 0.6N typical withdrawal force.
- Extended Mechanical Endurance: Qualified for a minimum of 500 mating cycles under harsh industrial thermal and mechanical stress.
Engineering Specifications & PCB Integration
Designed for standard 2.54mm (0.100 inch) grid through-hole PCB layouts, the terminal tail diameter measures Ø0.60mm ±0.02mm, requiring a recommended finished PCB plated through-hole (PTH) diameter of Ø1.00mm ±0.05mm. The total connector length scales linearly according to the formula 2.54mm × Number of Positions (±0.40mm), with a pin-to-pin pitch tolerance of 2.54mm ±0.10mm. Ensure wave or selective soldering profiles do not exceed +255°C peak temperature to maintain insulator dimensional stability.
