M12 Connectors for BUS Systems

Bus technology has advanced in industrial automation. The connectors required for data transmission are very BUS-specific. To access the complex world of Bus technology, Conec offers connectors for Profibus DP and Industrial Ethernet. For BUS systems, In2Connect offers M12x1 connectors with distinct coding which meets the guidelines of the PNO (Profibus User Organisation) and the IEC 61076-2-101 Ad. 1. The coding used for these products (B and D coding) prevent incorrect connections using standard M12x1 components. Connectors, overmoulded cordsets and splitters /adapters are all available. Due to their 8-pin design, the new X-Coded M12 connectors are compatible with RJ45 network cabling. Within the X-Coded connectors the 8 wires in the Ethernet cable are segmented into 4 shielded pairs.

Description

Description

M-style connectors are categorised by the size of the threaded locking nut; these include M8, and M12 connectors. Tough and robust, these waterproof, circular screw connectors are the de-facto standard in the process industry for reliable automated connections: protected to IP67. M8/M12 connectors provide a future-proof interface that supports higher-bandwidth needs, meeting the requirements of up to 10GB/s. All of the leading BUS protocols are also available.

These M12 connectors may also be coded. The common used keyed types are:

A-Coded; used in CAN-Bus, DeviceNet

B-Coded; used to prevent mating with standard sensor A coding and in field buses like Profibus DP

D-Coded; 4 pole used with Industrial Ethernet & Profinet. Ethernet M12 plugs and jacks with 100 MHz

X-Coded; 8 pole used in 10 Gbps Ethernet acc. to IEEE 802.3 CAT 6A –  X-Coded connectors are ideal for industrial network applications in harsh environments. It is possible to transmit up to 10 Gbp/s and the X-coding design conforms to IEC 61076-2-109. Overmolded male M12 double-ended cordsets and male M12 to male RJ45 CAT6A cordsets are currently available. All cordsets are available in standard 2, 3, 5 and 10 meter lengths. Suitable for Power over Ethernet (PoE, PoE plus, and UPoE)

Bus Systems

Bus technology has advanced in industrial automation. The connectors required for data transmission are very BUS-specific. To access the complex world of Bus technology, Conec offers connectors for Profibus DP and Industrial Ethernet.

Profibus is a manufacturer-dependent, open fieldbus system for a variety of applications in manufacturing, processing and building automation.

Industrial Ethernet is the general term for all applications that use the Ethernet standard to network devices used in industrial automation. In industrial applications, networks must operate without interruption under extreme conditions, e.g. electromagnetic interference, very high constant temperatures as well as high mechanical specifications. X-Coded Industrial Ethernet closes the circle, as it were, and creates a complete infrastructure, which stretches from the office to the machinery or even to the sensor.

For both bus systems, CONEC offers special M12x1 connectors with corresponding coding which meets the guidelines of the PNO (Profibus User Organisation) and the IEC 61076-2-101 Ad. 1. The coding used for these products (B and D coding) prevent incorrect connections using standard M12x1 components.

Short time-to-market requirements and high cost pressure make it necessary to build systems quickly, flexibly and reliably: the CONEC M12 field attachable connector with crimp connection offers the appropriate solution and is available in A, B, D, and X coding. The turned crimp contacts can take stranded wire cross-sections from AWG 28 to AWG 22 (for X-coding) and from AWG 24 to AWG 18 (for A-, B- and D-coding) and are thus suitable for a wide range of commercial industrial data cables. These machined crimp contacts provide a reliable and gas-tight connection to the stranded wire which ensures constant low resistance even in extreme conditions. In addition, the female connectors are also available with so-called closed entry contacts offering an additional plug-in security of the socket contacts. The crimp contacts can be processed with commercially available crimping tool and machinery, however the X-coded version requires a specific CONEC crimping tool plus selector. M12 Crimp connectors are protected against loosening due to vibrations during operation by a tactile vibration lock. The connector shell is entirely made of metal and therefore fully shielded. The connectors are designed for cable diameter of 4.5 to 8.3 mm and are 360° shielded.

Junction systems

Y junction boxes from CONEC with 5 pin connectors enable you to lay two incoming signals together at one E/A socket. This means that you can double your connection options for one actuator/ sensor box.

You can connect up to 16 initiators using one M12x1 junction box with 8 E/A sockets. Overmoulded components are also available for the output connection to the sensor. This provides a cost-effective and practical wiring system in the field for sensors and actuators with a cabling system that meets protection class IP67. Junction boxes are used anywhere sensor and actuator signals need to be extended quickly and easily for connection to their superordinate control systems. Individual signals are either connected directly to the superordinate system via a homerun cable or via a connection interface. Optional LED displays for signal and power reduce the effort required to track down errors.

Our product portfolio of passive distribution components has been expanded to include some new variants. In addition to the previously existing versions of Duo-splitter, i.e. T-splitter, a new Y-splitter line has been developed. This series provides a cost-effective and practical wiring system in the field for sensors and actors with a cabling system that meets protection class IP67. Junction systems are used anywhere sensor and actor signals need to be extended quickly and easily for connection to their superordinate control systems. Individual signals are either connected directly to the superordinate system via a homerun cable or via a connection interface.
Costs of wiring will be reduced and due to the pre-assembly connection faults can be excluded. A central mounting hole for M3 screws ensures secure attachment in the field. Many popular circuit layouts are available, see below. (Special circuits upon request).

Applications

Applications

M8 and M12 connectors are used in an incredible array of industrial applications like robots, sensors, vision systems, RFID and PLCs, actuators, electric motors, console lights, switches, valves, and contactors, the automotive industry plus machinery and tooling, packaging, factory automation, and food and beverage production areas. Due to the growing amount of data being pushed digitally across modern in-train networks, combined with shrinking system footprints, its history of use in rigorous industrial systems has proven the M12 connector very well suited to meet EN50155 for rail applications.

In industry, Ethernet cabling connectors come in a number of formats beyond the standard RJ45 – such as M12, push-pull V14, and IP67/68 protected circular connectors. Modern automation solutions need universal communication cabling for the different networks. Higher speed connectors are demanded in the circuit between the office world and the production level. Data bus systems like Profibus, DeviceNet and Industrial Ethernet each have their own defined type of connector and, in some cases, colour coding, contact arrangement and wiring code. The construction and design of the connectors that are necessary for data communication are bus-specific and should be carefully selected. Circular versions are available for Profibus DP, industrial Ethernet and DeviceNet protocols in several specifications. Conec M12x1 X-coded connectors have been developed for such applications. These components are designed for transmission technology according to CAT6A and 500 MHz/10 Gigabit, and are standardised to IEC 61076-2-109. These X-code connectors have 4 shielded pairs, for reliable high speed data transfer in such applications as vision systems and other high-speed data transfer: plus industrial grade materials for harsh environments, all in the small M12 connector.
The current product range includes patch cables in the standard lengths of 1, 2, 5 and 10 m as well as a female socket with pc tails for panel mounting. Manufactured using industrial-grade materials and machined contacts, the M12x1 X-code connectors combine reliable high-speed data transmission with rugged connector construction.

For the Food and Beverage Industries 4 and 8 way splitter boxes which have a stainless steel housing with a single incoming M23 connector or a factory fitted home run cable leading to either 4 way/4+ground or 8 way/4+ground M12 I/O ports are available.
