Frequently Asked Questions
What are the recommended panel cutout dimensions and maximum panel thickness for this M8 female socket?
This M8 panel-mount female receptacle requires a D-shaped anti-rotation mounting hole with a diameter of 8.1 mm (+0.1/-0 mm) and a flat edge width of 7.2 mm (+0.1/-0 mm) to fit its M8x0.5 rear mounting thread. It supports a maximum panel thickness of 4.0 mm, allowing secure engagement of the nickel-plated locking nut and NBR flange O-ring to maintain an IP67 seal.
How do the current, voltage, and contact sizes differ across the 3-pin to 8-pin M8 female configurations?
Electrical ratings are defined by pin density under IEC 61076-2-104 standards. The 3-pin (A-Code) and 4-pin (A-Code and D-Code) female sockets utilize 1.0 mm contacts rated for 4A at 60V DC. The 5-pin (B-Code) version uses 1.0 mm contacts rated for 3A at 30V DC, whereas the 6-pin (0.7 mm contacts) and 8-pin (0.6 mm contacts) A-Code models are rated for 1.5A at 30V DC.
What sealing and plating materials protect this M8 socket in harsh industrial environments?
The connector shell and M8x0.5 locking nut are machined from copper alloy with a corrosion-resistant nickel-plated finish. The internal female sockets are crafted from gold-plated copper alloy to ensure stable conductivity over at least 500 mating cycles. Dual black NBR O-rings and a black PA insulator provide IP67 ingress protection across temperatures from -40°C to +80°C.
What is the difference between the M8x1.0 and M8x0.5 threads on this panel-mount receptacle?
The connector features two distinct metric thread pitches for separate mechanical functions. The M8x1.0 thread is the standardized IEC 61076-2-104 interface thread that mates with external M8 male cable plugs, while the finer-pitch M8x0.5 thread (7.00 mm length) is dedicated to securing the receptacle body through the equipment panel wall using the included hex nut.
Overview and Application Notes
The M8 Circular Female Socket Connector is a compact, panel-mount device receptacle engineered in strict compliance with IEC 61076-2-104 standards. Designed for industrial sensor interfaces, compact actuators, and factory automation enclosures, this female panel receptacle features a standard M8x1.0 mating interface, an M8x0.5 panel locking thread, and 2.8 mm rear solder pins (solder cup termination) for secure wire-to-panel termination. It is available across A-Code (3, 4, 6, 8 pins), B-Code (5 pins), and D-Code (4 pins) configurations, delivering reliable IP67 waterproof protection when properly mated.
Key Features
- Multi-Coding & Pin Options: Supports A-Code (3, 4, 6, 8-Pin), B-Code (5-Pin), and D-Code (4-Pin) female socket configurations to prevent mismating across power, signal, and Industrial Ethernet lines.
- Precision Machined Construction: Built with a nickel-plated copper alloy shell and locking nut, gold-plated copper alloy female contacts, and a black PA insulation insert.
- Dual NBR O-Ring IP67 Sealing: Equipped with dual black NBR O-rings at the mating interface and panel flange to achieve IP67 dust-tight and waterproof ingress protection in the locked state.
- Reliable Electrical & Thermal Ratings: Rated for 4A at 60V DC (3/4-Pin), 3A at 30V DC (5-Pin), and 1.5A at 30V DC (6/8-Pin) across an operating temperature range of -40°C to +80°C.
- High Mechanical Durability: Tested to withstand a minimum of 500 mating cycles in high-vibration industrial environments.
Engineering Specifications & Panel Integration
Engineered for space-saving bulkhead integration, this M8 female receptacle requires a recommended D-shaped anti-rotation panel cutout with an 8.1 mm (+0.1/-0 mm) diameter and a 7.2 mm (+0.1/-0 mm) flat width, supporting a maximum panel thickness of 4.0 mm. The compact body measures 15.50 mm in length (excluding the 2.8 ± 0.2 mm solder pins) with a 7.00 mm rear mounting thread (M8x0.5) and hex wrench flats (10.0 mm / 11.2 mm) for secure torque assembly.
