Safety Switch STA
The robust metal safety switch STA is dimension-compatible with the proven EUCHNER safety switches TP and STP in plastic housings. Due to its die-cast aluminum housing and its high degree of protection IP 67, the switch can withstand even extreme ambient conditions. Like the switches TP and STP, the safety switch STA also offers a guard locking and a guard locking monitoring. A great variety of switching elements is available. The contacts can switch a minimum current of 1 mA. Therefore the safety switch STA is suitable for use in safe control systems.

Application:
Safety switches with separate actuator are suitable for sliding, hinged and particularly removable safety guards, which need to be closed to ensure the necessary operational security. They are also suitable for fitting on profile sections and existing equipment.
In combination with safety control modules all safety switches with class 2 shown in this chapter achieve Control Category 3 or 4 to EN 954-1.
Design and mode of operation:
On the safety switches with class 2, the switching element is not physically connected to the actuator but functionally brought together or separated for switching. When the guarding device is opened, the actuator is separated from the base unit. In the process, NC contacts are positively opened and NO contacts closed.
Enclosure rating of all the safety switches is IP 67. The safety switches can be fitted in any desired mounting position.
Schmersal make both standard and AS-i Safety at Work safety switches with separate actuator.

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.
- Polymer housing, three M20 or M16 knock out conduit entries
- Protection degree IP67
- 6 contact blocks available
- 8 stainless steel actuators available
- 30 N actuator extraction force versions
- Silver contacts gold plated versions
- Cylindrical or slotted fixing holes
- Cover with hinged opening and with only one fixing screw

Bernstein presents the innovative safety switch SLK as a solution to safety applications in industrial automation. The SLK performs a slim and compact enclosure as well as a mounting acc. per EN 50041 standard. The outstanding feature is the availability of a multi-supply voltage version covering a range from 24 V DC up to 230 V AC. The new actuator head allows both, horizontal and vertical, actuation. Turning the actuator head by 4 x 90° makes it easy to fit the SLK safety switch to various movable guards. The SLK features two independent safety circuits which monitor the position of the movable guard and the condition of the interlocking. Both circuits carry combinations of up to two forced disconnected contacts each and thus achieve compatibility with different safety systems.

Our huge standard programme with its diversity of housings has the optimal solution for almost any application. The various types of clamp or the dovetail connections directly integrated into the switch mean that the switches can be fitted on almost any type of cylinder. Our range also includes pneumatic cylinder switches for T-section cylinders. All the models can be supplied with dry reed contact with variable power capacities or in the electronic version. If you wish, we can develop completely new customer-specific sensors to meet your requirements.

Position Sensing Solutions
Bimba offers pre-tested Position Sensing Solutions for Bimba actuators. Our solutions provide a cost effective interface between the pneumatic actuators and electrical control systems. Our pre-tested solutions also eliminate costly, time-consuming design and fabrication required if switches are purchased separately and provide an aesthetically pleasing installation.
Both traditional Bimba switches as well as newer generations of Bimba switches are offered to allow for maximum flexibility to fit your application.
The switches perform the same functions as conventional limit switches. They can be used as position indicators, cycle counters, or to confirm operation.
All Bimba switches are designed to sense a magnet that is incorporated into the piston of the cylinder. Magnets are standard in Bimba MRS cylinders, but must be purchased as an option on other Bimba actuators.
A variety of outputs are offered for each switch family including PNP (transistor sourcing), NPN (transistor sinking), normally open contacts, and higher power triac.

The SIM08 connection box provides an optimal solution for connecting all type of cylinder end-stroke switches, with the following advantages:
Security. Front and rear signals are usually joined in two series. Yet, this solution doesn’t provide any protection to an eventual double signal or connection error and make it difficult the identification of a broken switch. The SIM08 box is equipped with an alarm to any double signal and a led light for each switch permits a fast detection of a non-working switch even if the signal is in series.
Versatility. The box can be fixed directly on the mold. From the box to the press machine there’s a unique connector (IP67 water resistance) with a 5 mt. cable. On the other side of the cable the end user can connect any type of connector - as per his Company standards - with min. 6 pins.
