PMAFIX Pro - NKNZ-M/P - Strain relief fitting

Product catalog summary

Overview: The document is a technical data sheet for the PMAFIX Pro - NKNZ-M/P strain relief fitting, designed for flexible non-metallic conduits with straight, metric threads. It is suitable for use in railway vehicles and heavy machinery, providing separation between damp and dry areas.

Key Features:

High impact resistance, even at low temperatures.
Integrated strain relief for optimal ingress protection (up to IP68/10 bar).
High connection strength to conduit and mating parts.
Easy push-in assembly with screwdriver dismantling to prevent unauthorized access.
Space-saving design compatible with both fine (T) and coarse (G) conduit profiles.

Ingress Protection: Rated IP66, IP68, and IP69 according to EN/IEC 60529, ensuring protection even with continuous motion.

Materials: The fitting body is made from high-grade polyamide 6, with nickel-plated brass threads and TPE-V sealing inserts.

Compatibility: Compatible with PMAFLEX Pro, Multilayer, and Smart Line conduits.

Standards and Compliance: Conforms to EN 45545-2 HL3, NFPA 130, UL 94 (V0), and UL 1696. It is RoHS and REACH compliant, free from halogens and cadmium.

Product Selection: The document provides a detailed table of part numbers, thread sizes, conduit sizes, cable clamping ranges, dimensions, and packing units.

Sealing System: The UNI sealing system ensures optimal clamping force transfer and pressure distribution, providing sealing up to IP54 even when not fully tightened.

Mechanical and Thermal Properties: Includes tensile modulus, tensile strength, and impact test values. The continuous application temperature ranges from -50°C to +105°C, with short-term exposure up to +160°C.

Fire Safety Properties: Non-flame propagating, with a flame class of V0. It meets various fire safety standards, including EN 45545-2 and NFPA 130.

Content of Delivery: Includes fitting body, locking and sealing elements, and Pflitsch sealing insert.

Assembly Instructions: Refer to the website for detailed assembly instructions and additional data sheets.

PMAFIX Pro - NKNZ-M/P - Strain relief fitting-3

— Sealing system Graduation of the clamping area in the UNI sealing system achieves optimal transfer of the clamping force to the cables. Distribution of the pressure through the sealing insert avoids damage to the cables. At the same time optimal sealing and strain relief are provided. Even when not completely tightened the sealing insert membrane offers sealing to IP54. Temperature range sealing insert Pflitsch: – 40 ... + 135 °C If several conductors are used with the connector multiple sealing inserts should be considered. Seal connection UNI Dicht To be screwed into the housing. Holds the...
