Frequently Asked Questions
What cable outer diameters (OD) are supported by this M12 right-angle field wireable socket?
The B-Code 5-Pin and D-Code 4-Pin versions accommodate cable outer diameters of 4mm to 6mm. Within the same housing series, A-Code (4, 5, and 8-Pin) configurations support both 4–6mm and 6–8mm cable ODs, while high-power K, L, M, S, and T-Code versions are designed for heavy-duty cables with an 8mm to 10mm outer diameter.
How does the screw-clamp termination mechanism facilitate on-site field installation?
The connector utilizes internal stainless iron clamping screws paired with gold-plated copper alloy contacts and a black TPU contact insulation sleeve. Technicians can strip the cable jacket, insert individual conductors into the color/number-coded Nylon 66 terminal block, and tighten the screws with a standard screwdriver—eliminating the need for soldering or specialized crimping tools in the field.
How does this 90-degree M12 field-installable connector maintain an IP67 waterproof rating?
IP67 ingress protection is achieved through a multi-point NBR (Nitrile Butadiene Rubber) sealing architecture consisting of dual internal black NBR O-rings and a rear NBR cable seal compressed by a black Nylon 66 pressing nut and white Nylon 66 strain-relief clamp, operating reliably from -40°C to +80°C.
What are the electrical ratings and IEC standards for the B-Code 5-Pin and power coding variants?
The M12 B-Code 5-Pin female socket complies with IEC 61076-2-101 and is rated for 4A current and 60V DC using Ø1.0mm gold-plated contacts. Power variants in this series comply with IEC 61076-2-111, supporting up to 12A/630V DC (K-Code, S-Code), 16A/63V DC (L-Code), 8A/630V DC (M-Code), and 12A/63V DC (T-Code).
Overview and Application Notes
The M12 B-Code 5-Pin Female Right Angle Field Wireable Connector Socket is engineered for rapid on-site cable assembly and maintenance in PROFIBUS, Interbus, and industrial automation fieldbus networks. Designed in strict compliance with IEC 61076-2-101, this 90-degree angled receptacle features a reliable screw-clamp wire termination mechanism and a durable black Nylon 66 body (39mm × 38.5mm Ref.). Supporting cable outer diameters from 4mm to 6mm (with 6–8mm and 8–10mm gland options across the series), it achieves an IP67 waterproof sealing rating when mated. This field-installable platform is also configurable across A, D, K, L, M, S, and T codings (4 to 8 pins) under IEC 61076-2-101 and IEC 61076-2-111 standards.
Key Features
- Tool-Assisted Screw Termination: Stainless iron screw-clamp terminals allow secure, vibration-resistant field wiring without specialized crimping tools.
- Standard & Coding Compliance: Precision B-Code 5-Pin female socket interface compliant with IEC 61076-2-101 for fieldbus communications (also available in A, D, K, L, M, S, and T codings).
- Electrical Performance: Rated at 4A and 60V DC for 5-pin B-Code/A-Code configurations (up to 16A / 630V DC available in K/L/M/S/T power codings).
- Industrial-Grade Materials: Black Nylon 66 shell housing, pressing nut, and insulation core paired with a nickel-plated copper alloy M12x1 locking thread and Ø1.0mm gold-plated copper alloy contacts.
- IP67 Environmental Protection: Multi-stage NBR O-rings and compression cable gland seal protect internal terminations from dust, moisture, and oil across an operating temperature range of -40°C to +80°C.
Engineering Specifications & Field Assembly Guidance
This right-angle M12 field-installable socket is designed for space-constrained equipment cabinets and sensor interfaces where vertical cable routing is required. The compression pressing nut and internal white Nylon 66 cable clamp accommodate standard 4–6mm cable outer diameters for B-Code 5-Pin assemblies (with 6–8mm options for A-Code and 8–10mm for power codings), providing robust strain relief. During installation, tighten the M12x1 coupling nut and rear pressing nut (SW13 / SW16 wrench flats) to the recommended torque to ensure full NBR gasket compression and IP67 ingress protection over ≥500 mating cycles.
