Product: M8 4‑Pin Field‑Expandable Male Straight Plug — Screw Connection, Unshielded, Waterproof Key benefits — why you need this connector Reliable signal and power: gold‑plated contacts (pure copper) and a metal screw sleeve provide corrosion resistance and stable electrical contact for consistent data and signal transmission. Quick, tool‑free installation: threaded screw locking with an 8 mm thread and anti‑vibration design makes coupling and uncoupling fast and secure without tools. Field serviceable and versatile: field‑expandable design lets you terminate cables on site, reducing downtime and simplifying maintenance. What it is (function and compatibility) Standard M8 circular connector, 4‑pin, male, straight plug. Unshielded design intended for cable termination. Screw (threaded) locking mechanism with 8 mm thread connection compatible with M8 female sockets and common industrial interfaces. Construction and performance Screw sleeve: metal construction for mechanical strength and long service life. Contacts: pure copper contacts with gold plating to improve conductivity and resist corrosion. Protection: waterproof construction suitable for environments where moisture resistance is required. Mechanical design: anti‑vibration locking ensures connections remain secure in applications with movement or vibration. Practical advantages Reduces installation time with no special tools required. Durable materials minimize replacement frequency and service interruptions. Stable electrical contacts improve signal integrity in industrial applications. Typical applications (practical scenarios) Factory automation: connect proximity sensors, limit switches, and small actuators to control systems on the production line. Machine vision and instrumentation: link industrial cameras and measurement instruments to data acquisition systems where reliable signal transfer is critical. Fieldbus and embedded systems: use with actuators, fieldbus components, and computer/avionics signal interfaces that accept M8 4‑pin connectors.
