M12 connector-front lock panel plug-in connector with grounding pin, designed for industrial scenarios, adopts front panel fixing, nut outer locking structure, screw reinforcement at the connection, equipped with grounding pin to achieve leakage protection, brass nickel-plated material is corrosion-resistant and durable. Supports multiple pin core selection, easy installation, suitable for electrical connection needs in harsh environments.
1. Product Features
The connector adopts an innovative front-lock panel design. The nut is located on the outside for quick installation and removal. The connection is locked with screws to ensure stability. The built-in grounding pin structure effectively guides leakage and improves the safety of electricity use. The main body is made of nickel-plated brass, which has both high strength and corrosion resistance, and is suitable for harsh industrial environments such as humidity and dust. The male and female pins adopt high-precision stamping technology, with low contact resistance and excellent conductivity to ensure stable signal transmission.
2. Product size and number of pins
Size specifications: Two thread specifications of M12×1.0 and M16×1.5 are provided to adapt to different installation scenarios. The male head has a main body diameter of 24.5mm and a panel opening size of 16.0×20.0mm; the female head has a main body diameter of 24.5mm and an outer nut size of 3.0mm, taking into account compactness and installation compatibility.
Number of pins selection: Covering multiple specifications such as 4-pin core (A type/D type), 5-pin core (A type/B type), 8-pin core (A type), 12-pin core (A type), etc., with clear male/female pin arrangement (such as A type 5-pin core male pin is distributed in a ring), meeting the signal and power mixed connection requirements of different devices, and strong adaptability.
