I/O connectors for different purposes

1.For simply connection

Regardless of the presence or absence of the programming interface, the switch type Profibus has been redesigned to meet the mechanical installation requirements of the new Siemens S7 controller. The outer contours of these newly designed Profibus cables ranging in diameter from 6 to 9 mm have been adjusted, all components are permanently preset and integrated with cage clamps. In addition, Profibus also uses ERNI's latest generation of D-sub connectors.


The termination area is hinged to its lid and is capable of consolidating its lid by using the center. This type of locking will simultaneously activate the stress relief of the cable as well as the shielded connection. In order to meet specific needs, the cable terminations are proven technology: insulation replacement (a fast termination option, ie no need to strip the wire insulation), cage spring clips and screw terminal terminations. Different termination and stress relief options provide maximum freedom for the user in connector termination. The standard Profibus type termination is a cage spring clip with a cable diameter of 8 mm. The Profibus type is also set to handle data signals with transmission rates up to 12MB/s.


2. For network connection

The most widely used connector system in the network is the 8-pin "RJ45" connector (8P8C). For this type of connection, the modular jack connector system delivers superior and economical transmission quality with termination or solder termination or surface termination. In addition to single-port, combined, and stacked ports, many product portfolios include filter module sockets. Typical modular jacks are available in 4, 6 or 8 pin versions and are available in unshielded or shielded options. The size pattern and printed circuit board layout of the filter module socket are similar to the standard type. The signal can be transmitted to the front panel via a panel socket or panel coupler.


The broad portfolio of filter module sockets also includes the Power over Ethernet (PoE) type. For applications that require IEEE802.3af compliance, the filter module socket provides the appropriate power through the data dual or idle dual line. In this way, standard CAT-5 cables can be used for data transmission up to 100m and power. As for the receiver, the 48V power supply can be converted to 5V or 3.3V. The filter module socket for PoE-capable 10/100 Ethernet provides angled single port and combined port configurations (1 x 2, 1 x 4), and the complete shield combines an effective ground connection. In addition, ERNI offers newer Gigabit and low-profile versions, as well as integrated LEDs in different colors.

3. For field sensor and brake connection

The M8/M12 connector is now recommended for almost all fieldbus specifications and is compliant with the IP67 protection level according to the IEC61076-2-101/104 standard. It is traditionally used to connect sensors and brakes in automation technology: corrections in this standard The 4-pin connector that describes D-code for industrial Ethernet applications has a high level of protection. According to the EIA/TIA standard, the M8/M12 connector corresponds to the transmission technical conditions of the Category 5 modular socket (RJ45). The use of D-code prevents it from mis-engaging with A-code (for sensor and brake wiring) and B-code (for some fieldbus).

The M8/M12 connector did not have a type of printed circuit board before this until 2005 when the surface-terminated terminal M8/M12 connector was born. Surface-mount terminations help miniaturize field devices. The sturdy pins enable it to pass through the batch packaging and the corresponding feeding process of the vibrating bowl. Another packaging method is tape and reel packaging. The basic modular design concept creates connectors of various mounting heights and different pin types. Based on the user's needs, the termination methods provided include surface mount, crimp or via reflow technology, which is based on surface mount technology. The black insulator of the connector is made of high temperature plastic, so there is no problem in all conventional surface mount soldering procedures.

In the past, controllers in switchgear cabinets used field devices through I/O cards. Today, industrial automation tends to be decentralized systems, and field brakes and sensors are often connected to a passive or fieldbus-enabled I/O box. In order to provide solutions for multiple applications at the lowest cost, specific field devices require a high level of modular flexible connector solution. To this end, the various printed circuit board types of the circular M8/M12 connectors are supplemented by cable systems. Different model shapes, pin counts, cable quality and length help achieve cost-effective and custom automation solutions.
