Command devices are of great importance for the man-machine interface in the area of industrial applications. For example, they are mounted in switch-boards, control panels, two-hand control panels, in lift manufacture and on materials-handling plants, including conveyors. Manual actuation of the devices starts operating sequences and functional processes or serves to bring these to an end.
Emergency Stop command devices are generally connected in the safety circuit of a machine or plant and are of particular importance in terms of the control system for these. In case of a fault or accident, the secure function and quick accessibllity of Emergency Stop command devices can be crucial for saving life, limiting the degree of injury to personnel or the extent of damage to a machine.
New requirements are placed on the mode of operation of these command devices by the new harmonised European Standard EN 418 regarding functional aspects and recommendations for the arrangement of Emergency Stop equipment.

Explosion proof switches are used wherever the ambient conditions are such that the presence of inflammable substances, oxygen and a source of ignition are to be anticipated simultaneously. The primary applications are to be found in the chemical and petro-chemical industries as well as paint lines. Protection against explosions is often also necessary where a large collection of line powder can develop such that a movement of air can lead to a spontaneous detonation. Examples include mills, wood processing and food processing industry.

SAFETY CODED MAGNETIC SENSOR, SR series
Pizzato Elettrica extends its range of safety magnetic sensors by introducing the SR A series which distinguishes itself from the SR B series in the reduced dimensions.
Both series are devices studied to monitor protections and guards that, when linked to a safety module, can create a system up to safety category 4, according to EN 954-1. These products are composed by a magnetic field monitoring sensor, which is connected to the machine structure; and by a coded magnetic actuator, which has to be connected to the mobile guards. The sensor is manufactured to be activated only by the correct coded actuator and not through a common magnet.
Pizzato Elettrica safety sensors distinguish themselves by following main features:
- Insensitivity to dirt as totally sealed, making them especially proper to be used in the food-industry sector.
- Wide actuation zone, characteristic appreciated in the use of inaccurate protections or for protections that can change their mechanical characteristics through the time.
- Centering mark on the housing as a reference for the operating distances
- Possibility of connection in series more sensors also with mechanical switches.
- Actuation from two different directions.

Non-contact safety switches provide considerable advantages where tough ambient conditions apply. They are also especially suitable for use on imprecisely controlled safety equipment. Non-contact EUCHNER safety switches operate on the basis of clearly coded actuators. Manipulation of an actuator is thus impossible. Supply voltage and data transfer to the coded actuator are realized by means of a non-contact inductive read head. A monitoring output is additionally available for the safety outputs. Through the redundant design of the evaluating device, the safety switch can be used for the highest safety requirements up to control category 4 according to EN 954-1.

The FailSafe GuardSwitch is designed as a safety interlock to be attached to a machine's guard or door. Unlike a standard reed switch 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 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.

Safety-/ position switches
Monitoring safe positions with LS-Titan
safety position switches From material handling systems to plastic injection moulding; from car washes to doors on trams: the position switches LS-Titan are used wherever there is exact positioning requirement.
The analog position switch with a voltage or current output also enables a range of new applications for the LS-Titan, where mechanical position detection could only provide insufficient information up to now – for example, detecting the position with opened flaps for flue gasses.
World innovation – the electronic position switch LSE-Titan®
electronic position switch The electronic position switch LSE has an operating point that can be set variably. Two fast and bounce-free PNP switch outputs enable high switching frequencies. They are protected against short-circuit and overload and are equipped with an abrupt switching behaviour. This guarantees a defined and reproducible operating point.
The actual operation point is in a range between 0.5 mm to 5.5 mm (supplied ex-works = 3 mm). The setting to the “new” operating point is performed as follows: The plunger must be moved from the “old” to the “new” operating position. Now the set button should be pressed for a duration of 1 sec. The LED now flashes with a higher pulse frequency and the new operation point is set retentively.
