Limit Switch (Mechanical)

  • This device is used to monitor mechanical movements and end positions.
  • It is a controlling sensor for electronic and mechanical sequences.
  • It also registers axial disengaging movements, e.g. on EAS-clutches.

Limit Switch (Contactless)

 

  • This device is used for measuring and monitoring axial and radial disengaging movements, e.g. on EAS-clutches.
  • It acts as a control sensor for electronic and mechanical sequences.

Limit Switch (Contactless, Magnetic Field-resistant)

  • The magnetic field-resistant limit switch is used for monitoring and measuring axial or radial mechanical movements and adjustments e.g. on EAS-clutches. 
  • Magnetic field-resistant or welding-resistant proximity switches are used where strong magnetic fields can influence the function of the proximity switch.
  • For example, they can be used in the field of strong magnetic coils as well as welding guns or welding electrodes with high welding currents.

Limit Switch (Contactless, with Mounting Flange)

  • The inductive proximity switch monitors and detects operating conditions on EAS overload clutches.
  • Axial movements caused by overload or switching procedures are registered by the proximity switch.
  • The signal can be used for further process controlling e.g. for drive switch-off.

Limit Switch (Mechanical, Multi-directional)

 

  • The limit switch is used to monitor and measure axial or radial mechanical movements and adjustments e.g. on EAS-clutches.
  • The device is suitable for clutches with a minimum stroke of 1.1 mm with radial actuation and 0.9 mm with axial actuation.

EAS-Sm/Zr Control Unit

 

  • This unit is used to switch, control, monitor and to indicate overload for adjustable EAS-Sm synchronous clutches and EAS-Zr overload clutches.

ROBA®-brake-checker

A permanent overview of the brake operating conditions

  • sensorless condition monitoring
  • maximum operational safety by revealing safety-critical conditions and errors prior to their occurrence
  • not only able to energise safety brakes, but also to monitor them
  • reliable and wear-free, independent of the cycle frequency and count
  • can be used for a wide range of ROBA-stop® brakes
  • can be easily, quickly and inexpensively integrated, also into existing system


Safety becomes visible

  • In addition to the signal itself, the module also supplies for example through an optical interface, data on the switching time, the current, the voltage, the resistance, the power and the relative attraction current.
  • Using an evaluation programme, the customer can see whether everything is running smoothly or whether there is work that needs to be done.
  • Maintenance becomes plannable and also remote maintenance is possible.

  • decelerate devices and machines evenly and gently
  • sensorless condition monitoring
  • maximum operational safety by revealing safety-critical conditions and errors prior to their occurrence
  • can be easily, quickly and inexpensively integrated, also into existing systems
  • designed for an input voltage of 24V or 48V DC voltage

Half-wave Rectifiers and Bridge Rectifiers

 

  • Rectifiers are used to connect DC units to alternating voltage supplies, for example electromagnetic brakes and clutches (ROBA-stop, ROBA-quick, ROBATIC), electromagnets, electrovalves, contactors, switch-on safe DC motors, etc.

Phase Demodulator

 

  • Phase demodulators are used to connect DC units to alternating voltage supplies.
  • Due to automatic switching from the applied overexcitation voltage to the holding voltage, it is possible to energise brakes for shorter switching times with overexcitation and to reduce power dissipation after the armature disk has attracted.

ROBA®-switch 24V

Fast switching module ROBA-switch 018.100.2

  • load operation with overexcitation or power reduction
  • integrated DC-side switch-off (shorter connection time)
  • input voltage: 24 VDC
  • max. output current: 5A

Spark Quenching Unit

Reduces spark production on the switching contacts occurring during VDC inductive load switching

  • Voltage limitation according to VDE0580 2000-07, Item 4.6
  • Reduction of EMC-disturbance by voltage rise limitation, suppression of switching sparks
  • Reduction of brake engagement times by a factor of 2-4 compared to freewheel diodes

ROBA-takt switch gear

 

  • This unit is used to start, stop and to position by switching and controlling the mayr-clutch-brake units

ROBA-takt Circuit Module

 

  • This device is used to start and stop mayr ROBA-takt circuit modules and mayr-clutch brake combinations.
  • It can be used for alternating 24 VDC coil switching, if a 24 VDC power supply is available.

ROBA®-SBCplus

Safe brake control – applicable up to PLe and SIL CL3

In order for safety brakes to contribute towards risk reduction in machines and systems, they require a reliable control system. The safe brake control ROBA®-SBC is technically superior in every respect with regard to safety contactor circuits. The module, which has been type examination tested by the TÜV (Technical Inspectorate), can be deployed up to the highest Performance Level PLe and Safety Integrity Level (SIL) 3.
