Guard door monitoring safety switches, command devices with safety function, tactile safety devices, optoelectronic safety devices

Application:
The safety switches with separate actuators are suitable for sliding, hinged and especially for removable safety guards, which need to be closed to ensure the necessary operational security. They can also be fitted on profile sections and retrofitted on existing equipment.

Safety monitoring modules, safety controllers, safety bus systems

In the Safe signal processing section, you can find safety relay modules and safety controllers for various safety technology applications (e.g. for emergency stop and guard door monitoring) as well as centralised programmable safety controllers and decentralised field bus systems, e.g. a modular concept for safety function control on small machines.

Safety-monitoring modules

• Stop category 0 (multifunctional)
• Stop category 1 (multifunctional)
• Combination (double evaluation)
• Two-hand operator inputs
• Stop category 0
• Stop category 1
• ATEX applications

Position detection, command and signaling devices

In the Automation technology section, you will find switching appliances for mechanical position detection in various fields of application as well as (safety) sensors with different operating principles; this section also includes a comprehensive programme of command and signalling devices.

Automation technology (Non-safety products)

• Command and signalling devices
• Foot switch
• Inductive proximity switch
• Position switch
• Magnetic reed switch
• Pull-wire switches
• Rotating spindle limit switch
• Slack-wire switch
• Belt alignment switch
• Gear-switches
• Micro switches
• Photo-electric proximity switches
• Downstream Devices

Application:
The solenoid interlocks of the AZM series have been designed to prevent, in conjunction with the control part of a machine, e.g. fail-safe delay timers or fail-safe standstill monitors, sliding, hinged and removable safety guards such as fences, flaps or doors, from being opened before hazardous conditions (e.g. run-on movements) have been eliminated.
These solenoid interlocks are also used for cases in which the opening of a guarding device represents a non-permissible intrusion in a production process.

Application:
The position switches with safety function are suitable for sliding and hinged guards, which need to be closed in order to ensure the required operational safety.

In combination with safety control modules all safety switches with class 1 shown in this chapter achieve Control Category 3 or 4 to ISO 13849-1

Further applications for positions switches class 1 are most varied positioning duties. A comprehensive range of actuating elements is available to meet the requirements of many everyday tasks.

Application:
The magnetic safety sensors are used to monitor the position of sliding, hinged or removable safety guards. Sensors without integral evaluation can only be used for safety duties to IEC 60947-5-3 in combination with a safety guard monitor for protection up to Control Category 4 to ISO 13849-1.

The use of magnetic safety sensors is of particular advantage in cases where extremely dirty conditions can occur or high hygienic standards need to be maintained. This is provided by the simplicity of cleaning of the devices.

Application:
Pull-wire Emergency Stop switches are mounted on machines and sections of plants which cannot be protected by guards. The advantage of pull-wire switches over mushroom head Emergency-Stop push buttons is that the Emergency-Stop command can be triggered anywhere along the wire.

In combination with one of the AES and AZR range safety monitoring modules pull-wire Emergency Stop switches can be used for Control Category 3 or 4 to ISO 13849-1.

Application:
Optoelectronic safety devices are used to protect access to hazardous points or hazardous areas.

>SLG/SLC range safety light grids and light curtains can be integrated into the safety concept of the machine or plant even under tight space conditions by virtue of their very compact design.
These safety devices are also often used on presses to guard danger points or zones. Depending on the particular resolution of the safety light grids and curtains, protection of persons, hands or even fingers can be provided. SLG/SLC range safety light grids and light curtains achieve Control Category 4 to ISO 13849-1.

Application:
Tactile monitoring systems stop the hazardous movement in case of contact or when touched. The variety of application fields require different safety devices.
