CH20M – the new housing standard – is the perfect platform for customised electronic applications
Modern electronics housings have to meet many requirements
with regard to form, function and appearance. Safety relays and
controllers also need to have a modular, scalable and integrated
DIN rail housing concept.
Large front panels should enable the users of your equipment to
congure and monitor operations easily.
The modular OMNIMATE electronics housing system CH20M
offers a reliable, innovative and future-proof platform for your
applications – cost-effectively and with high process reliability in
manufacturing:
• Customised design for high recognition value
• A variety of housing widths from 6.1 to 67.5 mm
• Wide range of housing colours, e.g. signal yellow
Glass bre reinforced material (V0) for optimal mechanical and
thermal stability
• High reliability and interference resistance through ESD-proof
design
• Larger net PCB layout surfaces up to 9,000 mm² (single sided)
Reliable operation and high serviceability are ensured through
numerous innovative details. This includes, for example, nger
safety on both sides and a leading pin contact.
In addition, a lead-sealable hinged cover prevents unauthorized
access
To ensure that your customers do not require additional docu-
mentation at the installation site, we can laser-print your circuit
diagrams onto the housing. Our international approvals open the
doors to global use of your safety equipment.

Housings
For the current and voltage supply you need reliable and
durable device connections. Plug-in connectors enable
particularly fast and reliable commissioning, while classic
PCB terminals are especially suited to price-sensitive
markets.
An important part of the OMNIMATE CH20M system is the
pluggable BHZ family with 5.00 mm pitch. This screw type
connector is maintenance-free, vibration-resistant and unique
on the market on account of its folded clamping yoke. The
Wire-Ready technology also makes connections easier:
prepare the conductor, connect, done. Locked-up terminal
points following long-distance transport are a thing of the
past.
To go with the BHZ connecter, we offer the SHL-SMT pin
header. It can be automatically assembled and is suitable
for reow soldering, which means it reduces your processing
costs during PCB assembly. The CH20M system also
provides the option of using a 5-pole DIN rail bus for the
power supply.
Our OMNIMATE Signal plug-in connectors BLZP and BLF
with 5.08 mm pitch are suitable for use in other housings.
They are equipped with specic solutions and increased
safety features such as our protection against mismating.
Depending on the application, you can choose between
spring (“PUSH IN”) or screw connections.
The OMNIMATE Signal PCB terminals LSF with 3.50 to
7.62 mm pitches serve as a non-pluggable “PUSH IN”
solution and are also compatible with both the wave and
reow soldering processes.

Power supply
PCB terminals and plug-in connectors create reliable connections
Devices must be able to communicate with each other, to
report errors, for example. Interfaces are also needed for
programming and conguration purposes. You may even
want to integrate decentralised units from the eld or install
a system for remote maintenance.
The CH20M system provides many options for rapid, secure
data transfer. The 5-pole bus systems for the TS35 DIN rail
offer practical advantages, for example:
• Two connections for the power supply
• Three connections for alarm, control or bus signals
• Gold contacts for maximum accuracy
• High serviceability
The housings can be snapped onto the terminal rails for
direct assembly and are made for easy maintenance. To snap
them in and out, there is no longer the need for any lateral
displacement towards neighbouring housings.
The CH20M also comes in a standard RJ45 version.
Customised cutouts for individual interfaces are possible
even for small quantities – for example, for the integration of
DIP switches and SUB-D connectors.
Plug-in connectors in the BLDZ 5.08DN and BLDF 5.08
series have an integrated cross-connection and establish the
bus connections to the individual modules on the front
panel.

Communications interface
Communication via industry-standard bus connectors for single-wire connections, RJ45 or bre-optic
Sensors in your process chains detect the respective
environmental conditions. Sensor signals can be in both digital
and analogue form. To operate your system safely over the
long-term you require increasingly precise signal processing –
which takes up as little space as possible.
Weidmüller has addressed this trend and offers a range of
products for signal processing that is tailored to the
requirements of sensor signals. The BL-I/O, for example.
This is the smallest pluggable solution in the 3.50 mm pitch for
3-wire connections.
• The integrated signal display indicates the correct wiring of the
sensors without the need for a control unit to be switched on
• The built-in potential distribution provides eight sensors with
the necessary power
• Robust “PUSH IN” conductor connectors ensure the stable and
secure functioning of sensors
Additional pluggable solutions in the 3.50, 3.81 and 5.00/5.08
mm pitches provide almost limitless possibilities for design at the
connection level. The modules can be produced economically
from a wide range of pin headers and are ready for the
automated SMT process.
Our PCB terminals with “PUSH IN” connections provide you with
a cost-effective alternative to our pluggable solutions.

Signal input
BL-I/O PCB plug-in connectors with “PUSH IN” connections for the highest packing density PCB Connectors B2CF with 3.5 mm pitch with double-row “PUSH-IN” connection
In a safety-related process, the actuators of your system not
only require precise status information, they also need, above
all, secure connections in order to drive relays, valves or motors.
These should have a design as compact as possible, except in
cases where the cross-section, conductor length or switching
voltage necessitate a larger construction.
Our compact B2CF plug-in connectors are noted for their high
connection density and good usability:
• With a 3.50 mm pitch, up to four levels can be installed on
top of each other with a maximum connector cross-section
up to 1.5 mm²
• Connecting the wires of the actuators is extremely time
saving and safe thanks to the “PUSH IN” spring design
• For higher gauge cross-sections, the BLF 5.0x with “PUSH IN”
connection is particularly well-suited
Because installation errors with such sensitive applications
can have serious consequences for both man and machine,
our BHZ connectors in the CH20M housing solution are
protected against mismating with captive coding and clearly
identiable markings.
And for error-free wiring on site you can also have your own
connection designations printed on all OMNIMATE Signal
products.
