Safety Components

Wieland Electric makes sure your machines have complete access protection from the input sensors to the control panel. Logistics, material handling, presses, robotics, and packaging machinery can all benefit from our selection of compact and approved safety technology. We offer protective sensor technology, such as optoelectronic switches, emergency stop switches, safety relays, and fully-loaded safety logic controllers.

All of our functional safety components have global approvals and meet the latest in industry health and safety standards.

Programmable Safety Controller

The samos® PRO COMPACT controller is easy to integrate, user-friendly, and compliant with the most up-to-date safety standards. It is also easy to program with the license-free safety software samos® PLAN 6.

Features include:

  • Integrated Ethernet protocols: EtherNet/IP, PROFINET, Modbus TCP
  • Compact 45 mm size
  • The main module has 16 safety inputs and 4 safety outputs, which can be expanded to over 100 safety I/O
  • Tolerates temperatures from -25 °C to 65 °C
  • Programmable via Ethernet, mini-USB, or SD memory card
  • Connection via push-in or screw terminals
  • Enables on-site diagnostics through integrated LEDs and remote diagnostics through Ethernet
  • License-free software with certified function blocks and easy verification and validation


Safety Relays

Our compact safety relays can be adjusted to fit diverse applications and connections. Their excellent technical performance, safety, and economy ensure effective individual safety function monitoring. Features include individual connections with push-in or pluggable terminals, large LED displays, compatibility with various safe sensors, and power switching of DC/AC loads up to 8A.



Optoelectronic Protective Devices: Safety Light Curtains and Light Grids

The Wieland Electric safety light curtains and light grids enable the safe operation of hazardous machinery or work areas. They reliably detect the presence of fingers, hands, or other body parts and signal the machinery to pause and resume accordingly. Our light curtains and grids are effective and easy to use. Features include:

  • AOPD type 4
  • Safety Light Curtains: Protection field heights from 300 up to 2100 mm
  • Safety Light Grids: Protection field heights from 500 up to 1200 mm
  • Standardized connection technology (M12)
  • Safety Light Curtains: Range up to 30 m can be implemented
  • Safety Light Grids: range up to 70 m can be implemented
  • Configuration without the need for software
  • Safety Light Grids: 2-, 3- and 4-beam systems
  • Base and Standard-Muting variants available
  • Accessories for installation, mounting and muting optional available
  • Up to PL e / Category 4 (EN ISO 13849-1)
  • Up to SILCL 3 (EN 62061)


Safety Interlocking Devices: Safety Light Curtains and Light Grids

sensor PRO safety switches with guard locking are ideally suited to prevent uncontrolled opening of a safety guard before the machine comes to a safe standstill, thus enabling personal and process protection. The rotatable head of the safety switch and the different actuators guarantee a high degree of flexibility in use. Variants with M12 connection plugs also enable simple and quick installation on the machine.

  • Flexible mounting to suit the application and available space
  • Suitable for personal and process protection
  • Easy adaptation to guards, doors and covers
  • Simple and quick installation on the machine
  • Suitable solution for any electrical installation
  • 360° rotation of the head (stepwise in 90°) as well as horizontal and vertical actuation possible
  • Safety switch according to the open-circuit or closed-circuit principle
  • Different actuators available
  • Variants with M12 connector plug
  • Flexible contact assembly



sensor PRO emergency stops are available as ready-to-use or configurable devices which enable highest flexibility to meet any application request. Wieland’s emergency stop switches are optionally available with self-monitoring contact blocks to guarantee best functional safety. In addition, variants with M12 connection allow easy and quick installation on-site.

  • Ready-to-use or configurable emergency stops
  • Tamper-proof according to applicable guidelines/standards
  • Variants with self-monitoring contact blocks
  • Switching position indicator
  • Suitable for applications up to IP69K


Safety Software —samos® PLAN 6

Following hardware installation, the Wieland safety software—samos® PLAN 6—allows for simple programming of sophisticated safety features. Thanks to our vast library of predefined and TÜV-certified safety-related function blocks, you can program with confidence. Our software is able to simulate and record all program safety-related function blocks, saving precious time during documentation.

We design all functions for maximum user-friendliness:

  • Automatic module configuration enables easy hardware selection
  • TÜV-certified, application-specific libraries of more than 65 function blocks
  • Special libraries for presses and muting
  • Fast verification and validation through oscilloscope function in offline and online modes
  • Automatic, configurable documentation at the push of a button
