DIN 41612 (EN 60603-2) / DIN 41617

DIN 41612DIN 41612 Two Part PCB Edge Connector

DIN 41612 (EN 60603-2) is a 2 piece backplane/daughter board connector in solder or Press-Fit technology that provides a versatile, high reliability, high density keyed interface between PCBs as used in telecommunications PC mainframes, test equipment, etc. DIN 41612 connectors are used in STEbus, Futurebus, VMEbus, Multibus II, NuBus, VXI Bus, eurocard TRAM motherboards, and Europe Card Bus, all of which normally use male DIN 41612 connectors on Eurocards mated with female DIN 41612 on the backplane.

Overview

The DIN 41612 standard describes a series of two-piece backplane connectors widely used in rack-based DIN 41612- 2telecommunication, computing, process control, medical, industrial automation, test and measurement and military/aerospace systems where long-term reliability is required. They typically consist of one to three rows of contacts in combinations of 16, 32, 48, 64, or 96 contacts on 0.1-inch (2.54 mm) grid pitch. These connectors are rated to 2 amps per signal pin, at 500 volts, although these figures may be de-rated according to safety requirements or environmental conditions. Several hybrid power and co-axial configurations are available. For over 30 years these DIN 41612 'Euro Card' connectors to IEC 60603-2 have offered a highly reliable system for board interconnects. Precision contact density, low mating forces, a two piece protective design and many contact termination styles offer unlimited design opportunities. Standardisation of the connectors is a pre-requisite for open systems, where users expect components from different suppliers to operate together; ept DIN 41612 are therefore fully intermateable with all other similarly compliant products from other manufacturers like Harting, Erni, Hirose and Tyco, etc.

The DIN 41612 standard describes connectors which may have one, two or three rows of contacts ~ rows a, b and c. Two row connectors can use rows a+b or rows a+c. The connectors will have 16 or 32 columns, which means that the possible permutations allow 16, 32, 48, 64 or 96 contacts to be loaded. The rows and columns are on a 2.54 mm grid pitch.

The most common connector in the DIN product line is type C, which is widely used in VMEbus systems, the DIN 41612 standard has been upgraded to meet international standards IEC 60603-2 and EN 60603-2. In the past, ept used a comb supported press-fit tool for their type C and B press-fit female connectors. To be more competitive, ept has changed to flat-rock technology (just a flat piece of steel pushed on the top of the connector) as used by many other manufacturers, for example Harting.

Termination methods include - straight PC, solder eyelet, wire wrap, crimp and "press fit" terminals. 

Insertion and removal force are controlled, and three durability grades are available. The headline performance of the connectors is a 1 amp per pin current carrying capacity, and 350 volt working voltage. Both these figures may need to be de-rated according to safety requirements or environmental conditions.

Applications

The DIN 41612 and sister DIN 41617 remain well proven, robust, reliable and low-cost products, particularly suited to rough, industrial environments. A typical application will have multiple daughter boards mated at right angles to a motherboard (backplane). The DIN 41612/IEC 60603-2 connector line from ept includes standard connectors and customer-specific connector technology solutions.

DIN 41612 (IEC 60603-2) Switching Connectors from ept

One ept refinement of the DIN 41612 is the "switching" connector. A principle often used for different bus systems is 'looping-through' of signal lines via module boards i.e. "daisy chaining". This daisy chaining, however, leads to a new problem, which becomes obvious when one of the modules is pulled from the system. The daisy chain signal connection is broken and must be re-established using jumpers. The integration of switches into a standard connector according to IEC 60603-2, e. g. into a female connector type C, is a simple and elegant solution for the problem described. The contact springs of the C female connector are extended by wing-like contact tabs. A gold-plated metal disk is located between the contact springs. In the rest position, with the male connector not plugged-in, the adjacent contact springs are short-circuited through placing of the contact tabs on the metal disk. With the male connector plugged-in, the contact springs are separated from each other through the contact pins of the male connector. The contact tabs of the spring are lifted off the metal disk. This interrupts the connection between the two springs. Due to the switching behaviour of the female connector, the daisy chain connection is automatically closed when the module board is pulled out. Function-wise the closed switching contact between two contact springs corresponds to a jumper automatically being plugged in when the male connector is pulled out. A switch can be integrated between any positions in the a, b and c rows of a C female connector IEC 60603-2 and/or between the a and c rows of a C female connector IEC 60603-2.

DIN 41612 Connectors for Railway Technology from ept

Highly rated classification I2 F1

The standards NFF 16-101 and NFF 16-102 serve to classify the non-metallic materials which are used in rolling stock applications with regard to flammability, smoke development and toxicity in case of a fire. The requirements for these connectors are derived from several factors such as the type of train, the frequency of tunnels it passes through and the mounting location of the connectors. From its broad range of DIN 41612 / IEC 60603-2 connectors ept
can offer C and F types with an insulator material that meets the high requirements of NFF 16-101 / NFF 16-102.
Other types are available on request. Read more..
