Ethernet connectivity for sensors in confined spaces
binder offers connectors with D-coding as part of its 818 product series
“Data rates of up to 100 Mbit/s and almost a third less space required than M12”: the D-coded M8 circular connectors of binder's 818 series ensure the space-saving and cost-efficient connection of miniaturised sensors in Ethernet networks, states the company.
binder offers connectors with D-coding in the M8 form factor as part of its 818 product series. The products are described as ideal for Industrial Ethernet applications with communication protocols such as EtherCAT, EtherNet/IP or PROFINET, according to IEEE 802.3 via twisted-pair cables of the Cat-5e category. Accordingly, the 4-pin connectors enable the network connection of actuators and sensors of particularly small size with data rates of up to 100 Mbit/s.
Optimised for space saving
Today, high-bandwidth Ethernet connectivity, beyond the field level and into the corporate data infrastructure, is a core component of automated processes in all branches of industry, says binder. “In the Ethernet communication of modern production facilities, for example in drives control, properties such as clock synchronism, real-time capability and determinism, but also reliability and robustness are in demand. Use cases in such environments place special demands on the connection technology, both from a technological and an economic point of view.
“Connectivity solutions should be designed to be variable and scalable, and above all support users in machine and plant engineering in saving space and time during installation. In addition, secure locking and protection categories appropriate to the field of application are required. M8 circular connectors with screw locking, in accordance with the DIN EN 61076-2-114 standard, are optimised for such application conditions. Here, the M8 form factor in particular has proven itself in installations where space is critical; the use with miniaturised sensors is exemplary for this area of application.”
Rugged hybrid connectors with PoE+
The binder series 818 products meet the requirements of data transmission in industrial Ethernet networks. Equipped with screw locking, the electromechanical connection meets the specifications of protection degree IP67 when mated and locked. “It thus offers adequate protection against the influences of harsh industrial environments.”
Beyond data communication, the hybrid D-coded M8 connectors take on the task of power supply in accordance with the IEEE 802.3at standard (Power-over-Ethernet-Plus, PoE+) to the connected devices.
Overmoulded and shielded or screw termination
The 4-pin D-coded M8 connectors are equipped with gold-plated and symmetrically arranged contacts, and are designed for more than 100 mating cycles. A rated voltage of 63 V(DC), a rated current of 4 A, and a rated surge voltage of 1500 V are specified for the products. The operating temperature range extends from -25 °C to +85 °C (idle state).
Shieldable products with screw termination and shielded, moulded cable connectors are available. While the former have a 4.0 to 5.5 mm cable outlet and are designed for 0.14 to 0.50 mm2 conductors, the wire gauge of the moulded variants is 0.34 mm2 (AWG 22).
In addition to straight male and female connectors, shieldable, angled flange versions are also available from binder.
