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.
- Available with cable or M8 integrated connector.
- Actuators with operating distance of 5mm or 8 mm.
The new sensor series complete the wide range of products that Pizzato Elettrica can offer in the machine safety field. For further information visit the web-site www.pizzato.com

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.

Door interlock switches are attached to the door of equipment where it is necessary to turn power on or off when the door is closed or opened. This type of control is used in applications where maintenance and testing must be performed inside a cabinet.
Interlock switches are supplied with one 1PDT snap action switch or two 1PDT miniature snap action switches.
The snap action switches are mounted in a frame and a single actuator, which is spring loaded, operates the switch.
When mounted in a door, the closing of the door forces the actuator against the spring thereby closing the switch.
When the door is open, the actuator springs out thereby opening the power circuit. The interlock switch has a service position, which allows service personnel to turn power on even when the cabinet door is open. When the door is closed, the switch automatically resets to the normal closed position.

Safety switches FR series
Pizzato Elettrica switches of the FR series with separate actuator reach the 4th generation. These switches are ideal for gates, protections, carter and all different guards which protect dangerous parts of a machine. The stainless steel actuator is fixed to the mobile section of the protection in order that every time the protection is opened the actuator is pulled out of the switch. A particular mechanism assures the positive opening of the electrical contacts by the pulling out of the actuator. These switches are easy to install and can be applied to any type of protection (hinged, sliding or removable). Furthermore the possibility of operating the switch only with the specific actuator assures that the machine can start again only when the guard is closed.
Pizzato Elettrica switches of the FR series distinguish themselves for the following characteristics:
- Rotating heads: by unscrewing the fixing screw the head can be rotated in 90° steps.
- Not detachable heads: the head “93” is perfectly interchangeable and compatible with the previous head “92” but it has the advantage that it is not detachable from the body, nonetheless it can rotate in 90° steps (Pizzato Elettrica patent). Practically speaking the new head is safer because it’s not possible to damage it during the installation.
The FR series complements the range of products that Pizzato Elettrica can offer to its customers. For further information, please visit the website www.pizzato.com or ask for the relative documentation.

Hinged machinery guards and covers as well as safety fence doors may be found in every type of industry. The Bernstein safety hinge switch SHS represents the integration of a safety switch in a load-bearing hinge for industrial applications.
The slim profile of the SHS allows the hinge to be readily mounted where space is constrained.
The operating angle is a full 180°, the switching point can be set between 0° and 180°.
The SHS hinge switch opens new doors with the safety contact mounted internally, inaccessible to the user and therefore providing excellent tamper protection.
2 SHS each with a forced disconnect safety contact allow safety category 4 systems to be configured subject to the required risk analysis and safety contact monitoring.
One or more SHS may be used dependent on the category of safety protection required.
Matching hinges without safety contacts are also available, allowing the style to be standardised for general use.
Connectors as well as fixed cable versions with axial and radial (rear) mounting are available.
An IP67 protection rating is sufficient for nearly all machine environments.

The XA and XW series of Emergency Stop switches include a revolutionary new technology called "safe break action" that will change the way E-Stop switches are designed. This innovative concept provides greater levels of human safety and is the first of its kind in the world.
Conventional E-Stop switches are designed with spring pressure on the Normally Closed (NC) contacts, keeping them in the closed position and allowing the machine to operate. Improper installation or excessive force to the stop button in an emergency may break or dislodge a vital part, causing the spring loaded contact to stay closed. This situation renders the E-Stop incapable of stopping the machine and can lead to catastrophic events, personal injury and possible loss of life.

SAFETY SWITCH WITH SEPARATE ACTUATOR FW SERIES
These safety switches are ideal to control gates, sliding doors and other guards protecting dangerous parts of machine. The stainless steel actuator is fastened to the moving part of the guard, so it is removed from the switch on every opening of the guard. The switch mechanism guarantees that removing the actuator forces the positive opening of the electrical contacts. Easy to install, these switches can be applied to any kind of protection (with hinge, sliding and removable ones). Besides, the possibility to actuate the switch only with its actuator guarantees that the machine can be restarted only when the guard has been closed.
