Keyed safety switches are used on sliding, hinged and removable guard doors that must be closed for operator safety. It is a two part system consisting of a switch body, mounted to the guard frame, and a separate actuator key, mounted to the door. Models are available in a several mounting profiles and housing materials. Each model has a variety of actuator key options: straight, right angle mounting, floating head, and keys integrated into door handle assemblies.
Solenoid locking switches are used on sliding, hinged and removable guard doors that must be closed and locked for operator safety. It is a two part system consisting of a switch body, mounted to the guard frame, and a separate actuator key, mounted to the door. Models are available in a several mounting profiles and housing materials. Each model has a variety of actuator key options: straight, right angle mounting, floating head, and keys integrated into door handle assemblies.
Position or limit switches are used with movable machine guards or detect the presence of materials. These switches feature positive break contacts which make them suitable for safety applications.
A variety of actuator options include plungers, roller plunger, roller lever, offset roller lever and angle roller levers. Actuation heads can be rotated to one of 8 positions to adapt to application requirements.
Hinged switches are used to monitor the position of hinged safety guards. They prevent machine operation while the door is ajar. Mountable on the inside or the outside of the safety guard these hinges offer adjustable switch angle and are available for left or right hinges doors.
Tactile safety devices offer a simple and easy to fit solution wherever crushing or shearing points are to be safeguarded, such as on elevating platforms, rising stages, sliding doors or industrial gates. Cascading mats are possible to increase protected area, special sizes and shapes are also available upon request.
The Schmersal foot-operated safety switch is used when the operator needs to start and stop a machine in a safe way while both his hands are busy, holding a work piece for example. Featuring a protective shield with wide opening these switches is available in single or double pedal versions.
Schmersal emergency stop button is a manual device allowing an operator to safely stop a machine in an emergency situation. Users can choose between a vast range of different variants. The product portfolio includes amongst other things, push buttons, mushroom head impact buttons, illuminated control push buttons and indicator lights, selector switches and selection buttons as well as key selector switches and key selection buttons.
The job of Schmersal’s two-hand controls or two-hand control panels is to ensure that the machine operators hands are located on the control panel when they issue the control signal for a hazardous movement. This prevents operators from reaching into the danger area after starting the machine or process. All Schmersal Group two-hand control panels are fitted with an Emergency Stop button that complies with EN ISO 13850.
Each Schmersal safety relay module can be adjusted to one of up to 11 present configurations which include selecting the type of reset, activating or deactivating cross-wire monitoring, and selecting the monitored contact configuration via a rotary dial on the front.
All versions of the family of safety relay modules PROTECT SRB-E can be used in applications up to Cat. 4 / PL e in accordance with ISO 13849-1 and up to SIL 3 in accordance with IEC 62061 / IEC 61508.
Schmersal PROTECT PSC1 modular safety controller is freely programmable using programmable software, SafePLC2. The compact controller PROTECT PSC1-C-100 can be expanded with up to 8 I/O expansion modules with up to 272 I/O. A mixture of centralized and decentralized structures can be used.
Safe standstill controller monitors the impulses of the connected sensors detecting standstill event using 1 or 2 impulse sensors. Permanent comparison of the input frequencies (actual value) with the preset standstill frequency (target value) makes it possible for the device to detect threshold violations and activate the safety outputs.
