Micro-One Wire-to-Board Connector System

Micro-One Connectors

Featuring an Independent Secondary Lock (ISL) that helps prevent accidental terminal back-outs, Micro-One Connectors maintain a secure electrical connection while enhancing mating retention and proper terminal insertion through their terminal position assurance (TPA) feature. These connectors support potting for protection against dust, moisture and corrosion in harsh environments and are Glow Wire capable, meeting stringent flammability standards.

Features and Benefits

Industrial and consumer applications can be subject to water ingress, shock or vibration issues and require potting for their PCBs. Micro-One headers feature a potting height of up to 7.00mm to cover the PC board.

Glow wire capable solutions are required to meet EU regulations (IEC60335-1) for the home appliance market. Micro-One headers have glow wire capable options.

Facilitating and maintaining secure electrical contacts and mating retention for small-size connectors, 2.00mm-pitch low-profile Micro-One Connectors feature an integrated ISL to prevent terminal back-outs and an independent TPA retainer to help position terminals.

If a customer needs multiple circuit connectors in different dimensions with matching mating components to meet varied design needs, Molex offers harness housing with integrated ISL and crimp terminals in a range of circuits and pitch options.

Independent Secondary Lock (ISL)

Designed to help position terminals and detect incomplete insertion, eliminating terminal back-outs and the need for quality checks for contact assurance.

Glow Wire Capable

Glow wire capable PCB headers were designed to meet required EU regulations (IEC60335-1) for the home appliance market. This test mandates that connectors carrying a current of 0.20A or higher must pass the glow wire test. A connector passes the test if, during 30 seconds of applying a glowing wire, there is no ignition or any flames self-extinguish within 2 seconds.

Potting Capability

Provides added resistance to shock and vibration and prevents moisture, liquid or corrosive agents from penetrating the PCB board. In addition, Micro-One Connectors provide a potting height of up to 7.00mm.

Micro-One Connector

Provides increased contact reliability
A gold-plated version helps prevent corrosion, improving conductivity and durability for customers requiring more robust connections.

Supports protective potting encapsulation
Potting boards with capable vertical-orientation connectors helps protect PCBs from liquids and corrosive agents, preventing exposure that can degrade the connector and PCB performance over time.

Delivers high performance in harsh environments
To avoid equipment degradation, gold plating protects contacts from oxidation when exposed to moisture. High-quality housing materials help the connectors withstand mechanical stresses and extreme temperature cycles that can damage the system.

Provides superior ergonomics and easier assembly
With a smooth, low-friction surface, gold plating reduces the mating force, which decreases the physical effort required during connector mating and improves operator efficiency.

Frequently Asked Questions

What are Micro-One Connectors?

The Micro-One Connectors provide a compact 2.00 mm-pitch, reliable wire-to-board solution that helps maintain a secure electrical connection while enhancing mating retention and proper terminal insertion through its TPA. These connectors feature an ISL that prevents accidental terminal back-outs. The robust design of these connectors helps ensure high performance in applications that are subject to vibration and shock. These connectors are ideal for applications including automotive, industrial, appliances and data center systems.

What is potting, and what benefits does it provide?

Potting is a process using protective material as an extra protective layer against shock, vibration, moisture and corrosive agents. Potting boards help prevent liquid or corrosive agents from penetrating the PCB board.

Are Micro-One Connectors compliant with environmental and safety standards?

Micro-One Connectors provide a UL94 V-0 flammability rating that helps ensure strong fire safety performance. These connectors are designed to meet RoHS and other international environmental regulations for hazardous substance control. These connectors are also UL/CSA certified, providing recognized assurance of quality and safety across global applications.

How do Micro-One Connectors provide a solution for home appliance applications?

Micro-One Connectors are Glow Wire compliant and rated up to 105°C, ensuring safe, reliable performance in appliances such as ovens, washing machines and dryers where heat exposure is common. These connectors offer enhanced sealing and durability against moisture, dust and vibration for long-term stability in demanding household environments as they support potting processes.
