Product description
Compact Modules with Ball Rail Systems and belt drive are characterized by their high power density due to their compact dimensions. Externally, the Compact Modules can be recognized by their relatively flat construction. The width to height ratio of all types is around 2:1.
Structure and attachments
Motor attachment – direct attachment with i = 1
The motor is attached directly to the compact module’s drive end enclosure via a motor mount.
Motor attachment – with gear
The planetary gearbox is attached by a mount. The mount serves to fasten the gearbox to the CRK and as a closed housing. Due to the connection without coupling, the drive torque is transferred to the drive shaft of the Compact Module with minimal torsional deflection. Available gear ratios: i = 3 (for CKR-145 and CKR-200), i = 5, i = 10

Mounting
Magnetic sensor with free cable end
1 Socket and plug
2 Sensor
3 Mounting duct
Alternatively, the sensor can also be attached by switch mounting plate and cable holder.
See the magnetic sensor with plug.
| 1) | Set screw for retention |
| 2) | Active surface |
Additional component/actuation
A mounting duct is needed to fasten the sensors and cable guides. This is suspended at the side in a slot at the Compact Module and secured with set screws (4).
The set screws are included.
The sensors are pushed into the upper T-slot (CKK/CKR-090,-110 and CKK-145) or into the lower T-slot (CKR-145, CKK/CKR-200) of the mounting duct and secured with set screws.
Switch activation is done by magnets in the carriage.
Socket - plug
Notes:
Socket and plug are not wired.
This allows optimal assignment of switching positions during start-up.
One plug is included.
The plug can be installed in three directions.
For further information, see the "Socket - plug” view.
CKK/CKR-200
Magnetic sensor with plug
1 Sensor
2 Switch mounting plate including set screws (loose) and square nut 2a
3 Cable holder including set screw (loose)
Attachment/Actuation
A switch mounting plate (2) is required to attach the sensors. This is suspended in the upper slot on the Compact Module and secured with set screws (4).
The sensors are pushed into the respective slot on the switch mounting plate and secured with one set screw.
The square nut with set screw (2a) serves as a fixed stop for the sensor (switching position when changing sensors). Parts are included in the scope of delivery of the sensor mounting kit.
Switch activation is done by magnets in the carriage.
Overview
Inductive sensors and mechanical switches for CKK/CKR-200
1 Socket and plug
2 Mechanical switch (with attachments)
3 Inductive sensor (with attachments)
4 Switching cam (attachment only at the connection plate)
5 Cable duct
Alternatively, the connection line of the switches can also be attached by cable holder.
Attachment/actuation
The switches are suspended in the upper slot on the Compact Module and secured with set screws (6).
The actuation is done using switching cams (4). This is attached with the screws to the connection plate. Fastening screws are included.
Cable duct
- The additional component is done in the lateral slots of the frame. Fastening screws widen the profile and give the cable duct a secure hold.
The cable duct will accommodate up to two cables for mechanical switches and three cables for proximity switches.
Fastening screws are included.
