The core unit is at the heart of your controls. It contains

the central processing unit (CPU), where all information is

processed. The output parameters will be determined by

the input variables.

Secure plug-in connectors with integrated cross-connections

like the BLDZ 5.08DN and the BLDF 5.08 represent the

bus interfaces to the individual modules on the front plate.

Alter natively, continuous contact for the DIN-rail buses can be

established on the back, as in the CH20M electronics housing.

The Ethernet protocol has become the standard for commu-

nications with the outside world. Weidmüller provides various

interfaces based on RJ45 and FO which are either located

directly in the component assembly or connected through a

bus interface.

You require industrial-quality, data connections to ensure the

data connectivity for your industrial controls. In particular, the

subassemblies which can be connected to an superordinate

Fieldbus system, e.g. PROFIBUS, PROFINET, CAN, SERCOS or

EtherCAT, make enormous demands on the quality of communi-

cation. Today, Industrial Ethernet is used predominantly in this

area and is the general standard for networking and con guring

automation components.

Based on our Industrial Ethernet components, we offer connec-

tion solutions in IP67 and IP65 for network connectivity and

position feedback. These are not only for devices, but for compo-

nents in the  eld as well. Our industrial quality data connections

guarantee secure data transmission. The interfaces comply with

international standard IEC 61076-3-106 (114).

There are sensors throughout the industrial process chain to

monitor the conditions at each step. These sensors send

signals in both digital and analogue form.

To ensure plant operation as automation steadily increases,

you need extremely precise signal processing – in the

smallest space possible.

Weidmüller offers a product range tailored to the require-

ments of sensor signals for signal processing. For example,

the BL-I/O is the smallest 3.50 mm pluggable solution for

connecting a three-wire system. The integrated signal display

shows the correct cabling of sensors even when the con-

troller is switched off. The integrated electrical distribution

supplies the needed power to 8 sensors. Solid PUSH IN

wire connectors guarantee that the sensors run continuously

and securely.

Additional 3.50, 3.81 and 5.00/5.08 mm plug-in solutions

offer virtually limitless design options at the connectivity

level. Our product range of male connectors means the

assembly components can be produced cost effectively and

are equipped for the automated SMT process.

PCB terminals with PUSH IN connectors offer you a cost-

effective alternative to plug-in solutions. They can be

produced in either the wave solder process or uncom-

promisingly in the re ow process.

For a secure process, the actuators need more than the

supply of precise status information; they also need highly

secure connections to control relays, valves, and motors.

And these should take up as little space as possible unless

the need for larger connection cross-sections, cable lengths

or switching voltage requires larger types of constructions.

Our B2CF plug-in connectors are both extremely compact

and easy to use. Up to four levels in pitch 3.50 mm can

be stacked to create a connection cross-section of up to

1.5 mm². The actuator conductors can be connected quickly

and securely using the PUSH IN spring action.

The BLF 5.0x with PUSH IN connection is well suited for

connection cross-section with particularly stringent demands.

When connecting sensors and actuators, modules are increasingly

being used outside the protected electrical cabinet. This means

that the module components have to be even more robust.

Weidmüller offers both IP65 and IP69K round plug-in connec-

tors depending on the application. The M8 and M12 round

plug-in connectors are widely recognised as the best connec-

tivity technology for wiring sensor and actuator signals for your

industrial applications. For motors and multi-pole cables, the

M23 products have been considered best-in-class for many

years now.

The product range is extremely broad, spanning across from

various built-in plugs to moulded cables, through to distributor

modules. In addition to the standard components, we have

also developed tailored solutions. For example, we can deliver

customised cable lengths starting with a quantity of one.

We also supply an IP67 housing which can be adequately

sealed without any additional moulding beyond its own

electronics module.

Modern controls in block or sliced construction need a modular,

scalable, universal housing concept.

Electronics housings carry out a multitude of functions: They

integrate, protect, isolate and connect the individual electronics

components and their operating and display elements. They

thereby become the interface in the electronics cabinet between

the various sensors, cable levels and actuators of the control

system.

The CH20M (Component Housing IP20 Modular) system offers

you an innovative platform for your applications and are primed

for the future. We feel sure that you will be extremely pleased

with the enormous degree of  exibility and customisation, whilst

delivering simpli ed planning due to standardisation. For exam-

ple, like a ”tailored suit off the rack“, CH20M uni es modularity in

a consistent design with extensive freedom to mix and match

along with vast scaleability.

Other bene ts include greater cost effectiveness and production

process security thanks to the automated assembly and re ow

processing (SMT) across all module widths as well as the greater

net layout space.

In terms of utilisation, the system features highly secure operation

and ease of use. Reliable operation and simplicity of service are

ensured by numerous innovative details such as integrated self-

coding, ergonomic release clips, being  nger-safe on both sides,

leading contact, as well as sealable and self-stopping hinged

covers.
