| To protect persons against risks of this kind, pressure sensitive safety professional mats are employed. At devices such as machines, machining centres, professional presses, industrial robot cells, high-shelf warehouses and many others, safety mats immediately switch off the power source, when the mat is stepped on. As long as the person stays on the mat, the machine cannot be set back into operation. |

Pull-wire emergency stop pushbuttons 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.
In combination with one of the AES and AZR range safety monitoring modules, see chapter 10.3, ZS range pull-wire emergency stop switches can be used for Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
All of the pull-wire emergency stop switches conform to European Standard EN 418. They have a positive linkage between the NC contacts and the wire rope. The pull-wire emergency stop switches are brought into the operational condition by pre-tensioning the wire, i.e. the NC contacts are then closed and the NO contacts open.
Schmersal make both standard and AS-i Safety at Work pull-wire emergency stop switches.

Pizzato Elettrica has designed and patented new accessories to install the rope of protective switches faster and to obtain an aesthetically more pleasant system.
The new accessories, in comparison with the traditional fixing system through carpentry material, have the following advantages:
%u2022 The installation is faster because only one screw is used for the fastening of every rope extremity, and the parts are prepared to ease the installation. Some practical tests have pointed out that the installation time is halved, reason for which it is named FAST.
%u2022 The system is aesthetically pleasant, because thread parts (which sometimes tear operators%u2019 dresses) and the rope extremities, usually fixed by heat-shrinkable sheath or supplier of adhesive tape, have been hidden.
%u2022 The red plastic covers of the fixing parts have been developed also for the function of controlling the rope clamping. If the rope fastening screw is not fixed tightly enough, the cover cannot pass.
%u2022 The rope is fixed without folds, thus reducing the rope stabilisation time and the possible re-calibrations of the rope tightening.
Furthermore two sturdy pulleys has been introduced in applications where the rope is very long in order to support the rope length or to bend its route. They are designed to avoid any deformation and to allow the rope to remain in its industrial seat also when it is energetically activated. |

Advantages
Pneumatic clamping with high forces
Optimum safety clamping - if the pneumatic fail the system is locked
The values of hydraulic manufacturer of clamps are reached and exceeded
Low system costs in comparison to hydraulics
Simple installation

The SITEMA Safety Brake type KSP is designed to hold a vertical moved mass in one direction (against gravity). The holding is done on a round shaft. This could be an already existing cylinder rod or a separate rod. The Safety Catcher can also be used to catch the falling load in case of an emergency-stop. The holding force is relatively big in one direction (downwards) and in the other direction (upwards) relatively small.
Safety brakes are already used in the following applications
- vertical or diagonal station tool axes
- vertical axes of loaders
|
|
The devices are approved by the authorities as a mechanical restraint device according to the European standard EN693.
SITEMA Safety Catchers are available for rod diameters from 25 to 360 mm. They are used for securing elevated masses (tools, lifting equipment) from sinking or even catching them in mid-fall. In already existing applications the weight of the masses being secured can exceed 100 tons. This function is of essential importance for protecting personnel and machinery, especially in manufacturers of hydraulic presses or tool machines.

| Omron STI safety interlock switches are available in a wide variety of models to satisfy most machine guarding applications. Models range from rope-operated emergency stop buttons, non-contact magnetic and hinge-pin-operated interlocks, to solenoid-actuated guard-door locking switches that restrict access until industrial safe conditions exist. All models conform to applicable U.S. safety standards and all carry the CE mark. |
|
| The FailSafe GuardSwitch is designed as a safety interlock to be attached to a machine's guard or door. Unlike a standard reed switching interlock, the circuit has been designed to have an "open" failure mode. If the main reed sticks closed when the guard opens, the in-line industrial fuse will blow, opening the circuit. If the watchdog reed sticks closed when the guard closes, the in-line fuse will blow, opening the circuit. The circuit will draw up to 4.5A to blow the fuse in less than 200ms. Along with being FailSafe, all the 200 series switches have non-coded actuators suppliers. |
|
| The 100 Series are non-contact interlock position switches with switching voltage models available up to 250 Volts. There are many models to fit a wide variety of applications. |

Optoelectronic protector device are used as entry, danger point or danger zone guards.
LS 30 range safety manufacturer of laser scanners detect invisibly and without physical contact over an angle of 190° and are mainly utilised as hazardous zone guards. The zone to be guarded can be individually definded, i.e. to suit the particular case, by means of user-oriented professional software. Up to two pairs of protection and warning zones can be monitored without the need for an additional safety monitoring module. By virtue of conventional means to guard the dangerous zone is either only realisable at the cost of high outlay or even completely impracticable, such as on pipe-bending machines, industrial industrial robots and automated guided vehicles (AGV). LS 30 safety professional laser industrial scanners achieve Control Categroy 3 to EN 954-1.

The PXS or PSS type products are sensors designed to control the opening of protective devices, machine casings and access professional doors.
Associated with their respective coded magnet and a controller module, they are capable of monitoring 1 or more "O" contacts
(break, closed with a magnet) and/or 1 or more "C" contacts (make, closed with a magnet). They meet the "CE" directives and
European regulations relating to machine conformity as per the standards EN60204 - EN1088 - En 954 and be covered by the
categories 1 to 4 of these standards according to the associated module (CETIM certificate).
Safety functions performed thanks to :
- Tamper-proof: the sensor, associated with its coded magnet, reduces the possibility of tampering ; a standard magnet cannot
actuate the sensor .
- Redundancy: the components are redundant. If part of the sensor fails, the redundant circuit continues to operate.
- Unbalance: associated with a controller module which checks the unbalance of the signals from the sensor, the first fault is
signaled if the switches are not actuated in the right order
Magnetic protection sensors represent an alternative to mechanical position switches in the following cases :
- Mechanical clearance required to overcome alignment or vibration problems,
- Compulsory complete sealing: industrial, food and mechanical environments,
- Longer lifetime and reliability. |
