AC
Micro Connector |
A keyed 3
connector style for AC sensors with 1/2 20-UNF thread |
|
Accessories |
Items helpful in
efficiently applying sensor technology such as mounting
brackets, etc |
|
Analog Output |
A sensor which
yields an output strength proportional to the distance to or
from the target. Such outputs are generally presented in
two forms: 0-10 volts or 4-20mA |
|
Cable Version |
Sensors with a
permanently attached cable, generally two meters in length.
The wires are generally stripped and tinned |
|
Capacitive Sensor |
A sensor which
emits an electric field and monitors the field for a change in
capacitance caused by entrance of an object into the field |
|
Connector Version |
Sensors
terminated with a connector (various types are available). Such
sensors require a separate cordset in order to connect the sensor.
This is a popular solution for OEMs where minimum installation and
replacement effort is required. |

Cordset |
Sensors
terminated with a connector (various types are available) require a separate
cordset in order to connect the sensor. This is a popular solution for
OEMs where minimum installation and replacement effort is required. |
|
Correction Factor |
A percentage of
the nominal sensing distance (sn)
which represents the sensing
distance for objects made of materials other than mild steel which has a
correction factor of 1. |

|
D-Type |
A capacitive
sensor capable of detecting nearly all objects. These sensors are also
shielded, allowing them to be flush
mounted. |
|
Hysteresis |
The distance
between the sensor operate point when the target approaches the sensor and
the turn-off point when the target moves away from the sensor, expressed as
a percentage of the sensor operate point. |
|
Inductive Sensor |
A
sensor which produces an electromagnetic field that senses
only metal targets. |
|
Load |
The required
device (LED, relay, PLC, etc) which is powered by the sensor output. |
|
L-Type |
A capacitive
sensor best for detecting conductive objects. They are capable of
sensing through fairly thick layers of non-conductive materials, and are
very well suited for liquid level applications. These sensors
are
unshielded. |
|
Micro Connector |
A keyed 3 or 4
pin connector style with M12 thread. |
|
N.C. |
N.C. refers to
the Normally Closed output type. Upon change in sensing state the
circuit opens. |
|
N.O. |
N.O. refers to
the Normally Open output type. Upon change in sensing state the
circuit closes. |
|
Nominal Sensing Distance |
The rated
operating distance for a sensor (Sn). At this distance the specified
performance criteria are guaranteed.
|
|
NPN
(Sinking) |
NPN refers to a
DC output type, also known as a "sinking" output. It is a transistor
output that switches the DC ground. The load must be connected
between the sensor output and the positive supply. |
|
Pico Connector |
A miniature 3 or
4 pin connector style with M8 thread. |
|
PNP
(Sourcing) |
PNP refers to a
DC output type, also known as a "sourcing" output. It is a transistor
output that switches the DC positive voltage. The load must be
connected between the sensor output and the DC ground. |
|
Shielded |
Shielded sensors
(also called embeddable) can be flush mounted in metal up to the plane of
their sensing face without significantly affecting the sensing
characteristics. |
|
Sinking (NPN) |
NPN refers to a
DC output type, also known as a "sinking" output. It is a transistor
output that switches the DC ground. The load must be connected
between the sensor output and the positive supply. |
|
Sourcing (PNP) |
PNP refers to a
DC output type, also known as a "sourcing" output. It is a transistor
output that switches the DC positive voltage. The load must be
connected between the sensor output and the DC ground. |
|
Standard Target |
Generally, a
square piece of mild steel having a thickness of 1mm, with the sides
equivalent to the diameter of the sensing face or the same size and shape of
the sensing face. |
|
Unshielded |
Unshielded
sensors (also called non-embeddable) cannot be flush mounted in metal up to
the plane of their sensing face without significantly affecting the sensing
characteristics. |
|
Ultrasonic Sensor |
A sensor which
detects objects by emitting an ultrasonic pulse and measuring
the time for its echo to return |
