M8 assembly type connectors provide a versatile solution for field installation. Available in both plug and socket configurations with 3 to 8 pin options using A code and B code keying, these connectors support a wide range of sensor, actuator, and equipment wiring applications where cable lengths and installation requirements may vary.
The series is available with either solder cup or screw terminal configurations to support different installation requirements. Metal shell solder cup versions provide permanent soldered connections while maintaining continuous shielding, while screw terminal versions simplify field installation where soldering is not practical. Designed for dependable operation in compact control and signal applications, these connectors feature IP67 rated sealing when properly assembled and mated. The connectors are rated for an operating temperature range of -40 °C~105 °C and a minimum durability of 1,000 mating cycles.

FAQs
When would I use an assembly style M8 connector instead of an overmolded cable assembly?
An assembly type connector may be preferential include applications where cable lengths need to be determined during installation, where existing cables must be terminated with a connector, or when field modifications may be required. Assembly type connectors also excel in low volume situations, where the versatility to use the same connector with multiple different wire diameters or lengths is beneficial. Overmolded cable assemblies are typically preferred when cable lengths and connector configurations are well defined, and volume is sufficient to justify a dedicated solution.
How to choose between solder cup and screw terminal assembly connectors?
Screw terminal connectors allow conductors to be mechanically secured using terminal screws, simplifying installation when soldering equipment or expertise is not available. To accommodate the larger terminals, there is a limit to the number of contacts that can fit within the assembly.
Terminating with solder cup assembly connectors require conductors to be soldered directly to the contacts, providing a secure permanent connection. This needs to be done with access to specialized equipment and requires more training to accomplish. One benefit to the connectors that utilize solder cups is that the metal shells allow for shielding.
What does IP67 mean for these connectors?
IP67 indicates protection against dust ingress and temporary immersion in water under defined test conditions. In the context of M8 assembly connectors, the connection between mated plug and socket connectors and the seal at the rear of the connector achieve IP67 ratings. Achieving the intended ingress protection depends on proper assembly, correct wire selection, undamaged sealing components and mating with a compatible connector.
Why does cable jacket diameter matter for assembly connectors?
Cable jacket diameter affects both sealing and proper assembly of the connector. A cable that is too small may not seal properly, which can compromise the IP67 ingress protection of the completed cable assembly. A cable that exceeds the connector’s maximum rated diameter may prevent proper assembly.
For proper fit, the cable jacket outer diameter must fall within the connector’s specified sealing and strain relief range. Depending on the connector, supported cable jacket diameters range from 3 mm to 7 mm. Refer to the product drawing or PDF specification for the exact range for each connector. Tensility also provides suggested compatible wires for each configuration.
