Amphenol PT06A-12-3P Connector Pin – Bayonet, 12‑Shell 3 Contacts

Description

Product Overview

The Amphenol PT06A-12-3P connector pin is a precision‑engineered component built to meet the rigorous demands of modern industrial electrical systems. Constructed from high‑grade alloyed steel, the pin offers exceptional tensile strength and resistance to corrosion, ensuring reliable performance even in environments with exposure to moisture, dust, and temperature fluctuations. The bayonet coupling mechanism provides a quick‑lock, secure connection that resists accidental disengagement while allowing easy installation and removal during maintenance cycles. With a 12‑shell size, the pin aligns perfectly with standard miniature cylindrical connector housings, delivering a compact footprint that saves valuable panel space. The three contacts are gold‑plated to reduce contact resistance and enhance conductivity, supporting high‑current applications without overheating. Solder termination points are strategically positioned to facilitate clean, repeatable solder joints, reducing assembly time and minimizing the risk of cold solder joints that could compromise system reliability.

Usage

Designed for general‑duty industrial wiring, the PT06A-12-3P pin excels in a wide range of applications, from factory automation equipment and control panels to robotic arms and sensor networks. Its robust bayonet design makes it ideal for vibration‑intensive settings such as conveyor systems, where a secure connection is critical to prevent intermittent signal loss. The pin’s compact 12‑shell profile enables integration into densely packed printed circuit boards (PCBs) and wire harnesses, making it a preferred choice for aerospace and automotive subsystems that demand both space efficiency and high reliability. Engineers often select this connector for power distribution modules, where the three contacts can carry separate phases or combine to handle higher current loads. The solder‑ready termination simplifies field repairs, allowing technicians to quickly replace or rework connections without the need for specialized crimping tools.

FAQ

What types of cables can be used with the PT06A-12-3P pin?

The pin is compatible with a variety of insulated copper conductors ranging from 20 AWG to 12 AWG, provided the wire is stripped to the appropriate length for soldering. For optimal performance, use cables with a temperature rating of at least 105 °C and a voltage rating that matches the overall system requirements.

Is the PT06A-12-3P suitable for harsh environmental conditions?

Yes. The pin’s alloyed steel construction, combined with a corrosion‑resistant coating, makes it suitable for environments with high humidity, dust, and temperature extremes. While it is not a sealed connector, it can be used in conjunction with protective enclosures or gaskets to achieve the desired level of environmental protection.

Can the pin be reused after removal?

Absolutely. The bayonet coupling is designed for multiple mating cycles without loss of performance. However, it is recommended to inspect the contacts for any signs of wear or oxidation after each removal and re‑solder the termination points if necessary to maintain optimal conductivity.

What is the recommended torque for tightening the mating connector?

Amphenol specifies a tightening torque of 0.5 Nm (4.4 in‑lb) for the mating connector to ensure a secure lock without over‑compressing the pin. Using a calibrated torque screwdriver helps achieve consistent results across multiple installations.

How does the PT06A-12-3P compare to other Amphenol connector series?

The PT06A‑12‑3P offers a unique combination of a bayonet coupling, compact 12‑shell size, and three gold‑plated contacts, distinguishing it from the PT01A series which uses a push‑pull lock, and the PT07A series which provides a larger shell size for higher current applications. Selecting the appropriate series depends on the specific mechanical and electrical requirements of your project.
