                         Bimba Position Sensing Switches

                                                Switches
                                                        Bimba offers Hall Effect, Magnetic Reed and Magnetic
                                                        Reed/Triac-type switches to meet a wide variety of
                                                        customer needs. Bimba actuators and switches provide a
                                                        reliable, cost-effective interface between the pneumatically-
                                                        powered functions of applications and the electrical
                                                        controls. They eliminate costly, time-consuming design and
                                                        fabrication of independent electrical limit switch
                                                        arrangements, and provide an aesthetically pleasing
                                                        installation.
                                                        The switches perform the same function as conventional
                                                        limit switches. They can be used as position indicators,
                                                        cycle counters, or to confirm operation. They may also be
                                                        used as safety devices by allowing for operation of second-
                                                        ary devices only when the actuator is properly positioned.
                                                        The Switch Application Selection Guide provides
                                                        information on which type of switch is suitable for a
                                                        particular application.
                                                        All Bimba switches are designed to sense the magnet that is
                                                        used in the MRS cylinder and in other Bimba actuators that
                                                        are ordered with the -M option. All are normally open
                                                        switches that close when sensing the magnet. Switch mod-

                                   Bimba Hall Effect Switch
This is a three-wire, solid state device recommended for low current DC loads such as interfacing with a
programmable controller. It provides compact, reliable sensing for virtually infinite life. An LED indicator light
illuminates when switching occurs. Models are available in current sinking (NPN) and current sourcing (PNP)

models depends on the requirements of the programmable controller.

                                                     How it works:




                                                                                                                                           Square Flat-1
In operation, a constant current is passed through the Hall sensor. When the magnet is not directly below the




                                                                                                                                             Flat-1 /
sensor, the current (flow of electrons) is evenly distributed across the chip. With an equal number of electrons at the
chip edges, no potential difference exists at the output. (V= 0, Fig. 1) When the magnet is directly below the sensor,
the electron flow is distributed by the magnetic field to one side of the chip causing an imbalance in the electron
concentration at the edges. This creates a potential difference, the Hall voltage, at the output.




                                                                                                                                           Square Flat-II
(V=VHALL, Fig. 2) This Hall voltage is detected and amplified to control a switching output transistor.

                                Hysteresis and Operating Windows
Hysteresis
Bimba Hall Effect switches are subject to hysteresis. Hysteresis is the difference in magnetic field strength needed
to initiate switch operation versus the field strength needed to sustain switch operation. The effect is that the switch
break point will be different from the switch make point in the piston travel.

Operating Window
The operating window is the distance the piston travels while the switch is in the “ON” state, and includes the
hysteresis action. For the Hall Effect Switch, hysteresis is greater on one side of the operating window because this
switch is sensitive to only one side of the magnet.
For high speed equipment, the time duration of the switch signal may be critical. The time duration is a function of
the operating window length and the speed of operation of the actuator. It is calculated by dividing the minimum
travel in the operating window by the piston speed, taking into account the hysteresis effect. The illustrations and
chart below show the operating windows for the Hall Effect Switch.
