COMPENDIUM
In General
Airgap
The switching distance of a sensor to a magnet or any other target to be
detected depends on several factors, including:
? Sensing characteristics of the sensor
? Magnet material
? Magnet dimensions
? Relative motion of the magnet with respect to the sensor
? Presence of nearby magnetic or ferrous materials
ESD Sensitivity
? Cherry Reed sensors are not solid-state devices and thus immune to ESD
? Several of our solid-state series sensors, among them GS1001-1004,
GS1012 and SD1012, are equipped with additional circuitry to enhance
ESD immunity. They have been tested for ESD immunity in accordance
with IEC publication 1000-4-2 using testing standard EN50082-2.
Other sensors, including MP1013, MP1021, GS1005-1009 and VN1015,
should be treated as ESD sensitive and handled like other ESD-sensitive
devices.
Connection
Depending on the type and version, Cherry sensors are equipped either
with a de?ned standard connector or with wires for individual connection.
Housing
Cherry sensors are delivered in ready-for-assembly housings for the indicated
protection class.
Vane Sensors
These sensors are actuated by vanes passing by the airgap. The ferromag-
netic vane thereby changes the magnetic ?eld between the sensor and the
magnet in the two arms of the fork.
Vane Material
In general, all ferrous materials should have suitable vanes.
We recommend iron or steel.
Vane Dimensions
We recommend a minimum vane material thickness of at least 1 millimeter
and minimum width of at least 6.35 millimeters. The vane should pene-
trate a depth of less than 3 millimeters from the bottom of the sensor slot.
