The Schmersal Group develops and manufactures safety switches, position monitoring, and non-contact protection of hazardous zones for a variety of machine level and plant wide applications.
AZM range solenoid interlocks, operating in combination with control elements of a machine, e.g. fail-safe standstill monitors or fail-safe delay timers, ensure that sliding, hinged and removable guarding devices, such as grids, hoods or doors, cannot be opened until hazardous conditions (e.g. running-down movements) have come to an end.
Everything on one handle. Less is more – that is the principle according to which Schmersal has designed the safety door handle series TG. The operator does not have to press a button on an external switching plate when the solenoid interlock at a safety guard needs to be unlocked. The switching function is now exactly where it is needed: On the safety door handle which is used to open the safety guard.
The magnetic safety sensors serve to monitor the position of sliding, hinged and removable safety guards. Sensors without integral evaluation can only be used for safety duties to DIN VDE 0660-209 in combination with a safety guard monitor for protection up to Control Category 4 to EN ISO 13849-1.
Pull-wire Emergency Stop switches are mounted on machines and sections of plants which cannot be protected by guards. In contrast to mushroom head Emergency Stop push buttons, on pull-wire switches the Emergency Stop command can be initiated from any point on the wire.
Safety light barriers
Optoelectronic safety device are used as entry, danger point or danger zone guards. SLB range safety light barriers are utilized as entry guards to dangerous areas. These protection devices operating without physical contact achieve Control Category 2 or 4 to EN 954-1 in combination with SLB 200-C or SLB 400-C safety monitoring modules.
Safety light curtains, Safety light grids
Optoelectronic safety device are used as entry, danger point or danger zone guards. 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 EN ISO 13849-1.
With this system, for example, safety-oriented and operational signals of control devices, as are typically to be found in mobile control housings can be transmitted without the need of wires. The system is especially qualified under factory environment conditions, as it is precisely here that all HF-critical disturbing influences, such as attenuation, reflections, absorption, diffusion, deflections, refraction and interference have such a particularly strong impact on a system of this nature.
