M12 X circular connectors of the Sensor Actor Line from CONEC are used to connect a distributor box and a sensor.

The M12 style connector comes with a screw lock, used for low voltage and has between 2 and 8 contacts. Conec M12 connectors are IP67 rated and well suited for wet, moisture-laden environments.

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

A-Coded; used with Sensor Actuators

B-Coded; used with field buses

D-Coded; used with Industrial Ethernet X-Coded; used with10 Gbps Ethernet

These connectors can be used to implement a flexible input-output (I/O) or field-bus connection on the circuit board. M12 connectors with D-coding comply with Industrial Ethernet standards (IEC 61067-2-101, Amendment 1). M12 connectors are now recommended for nearly all field-bus specifications, and meet the IP67 protection standards rating (IEC 61076-2-101). They are not intended for use under continuous pressure. In consideration of the broad range of ‘rained on’ definitions, the industry appears to have agreed to a ‘test of immersion for 30 minutes, at a depth of 1 metre, or the equivalent air test at 1.45 psi. That is the Qualification Test. (Protected against the effects of temporary immersion between 15cm and 1metre. Duration of test 30minutes). They are also traditionally used to connect sensors and actuators in automation systems. An expansion (Amendment 1) of the IEC 61076-2-101 standard describes a 4-pole, D-coded variant specified for a higher protective class of Industrial Ethernet applications ~ these requirements correspond to those of a Category-5 modular jack (RJ45) connector, according to the EIA/TIA standard. The D-coding prevents the connector from being confused with the A-coding used for sensor-actuator wiring, or the B-coding used with some field buses.

 

 

Moulded to cable

 

Over-moulded metric type connectors improve durability and streamline the size, as well as the appearance, of a cable connection. Over-moulding can also reduce the cost of lifetime ownership of cable assemblies, making it an important consideration for harsh environment applications. The extra strain relief around the wire terminations offers increased durability because the strain relief bonds to the cable jacket. These connectors, available with 3, 4, 5, 6, 8 and 12 contacts provide innovative connection technology fulfilling the requirements of protection class IP 67. The standard programme has moulded versions with anti-vibration locking and they come in various cable lengths and quality. Components with 2 or 3 LEDs are available to indicate operating voltage and/or the switching status.

 

When it gets really tough: Shielded connectors from CONEC protect and bypass weak signals. A uniform cable shielding ensures seamless signal transmission. Connection cables with a combination of connectors and/or adapters can be used for nearly any cabling application, plus they can be used on many types of machinery using capacitive, inductive or optical sensors.
