Does Turck Have A Glossary Of Sensor Terms I Can Reference?Yes, TURCK does provide a glossary of sensor terms, you can read it here.

Axial Approach
The approach of the target with its center maintained on the sensor reference axis.
Axially Polarized Ring Magnet
A ring magnet whose poles are the two flat sides of the disk. Mounted on pistons for permaprox cylinder position sensing through nonmagnetic cylinder walls.
Capacitive Proximity Sensor
A proximity sensor producing an electrostatic field that senses conductive targets and nonconductive materials having a dielectric constant  of  >1 within its sensing zone.
Complementary Output
Two outputs, one normally open and one normally closed, that can be used simultaneously.
Continuous Load Current
The maximum current allowed to continuously flow through the sensor output in the ON state.
Correction Factors
Percentage of the rated operating distance (Sn) that represents the operating distance for targets constructed from materials other than mild steel (mild steel’s correction factor is 1.0).
Differential Travel (Hysteresis)
The difference between the operating point as the target approaches the sensor face, and the release point as the target moves away. Given as a percentage of the operating distance (Sn).
Dynamic Output
A sensor output that stays energized for a set duration of time, independent of the time the target is present (one-shot).
Embeddable (Shielded) Proximity Sensor
A sensor that can be flush-mounted in any material without that material influencing the sensing characteristics.
Free Zone
The space around a proximity sensor that must be kept free of any material capable of affecting the sensing characteristics.
Inductive Proximity Sensor
A proximity sensor producing an electromagnetic field that senses only metal targets within its sensing zone.
Inductive Magnet Operated Sensor (Permaprox)
A solid-state proximity sensor using inductive technology to detect magnetic fields, giving a switch point output similar to that of an inductive proximity sensor.
Inrush Current
The maximum instantaneous load current that a sensor can tolerate when switching the output. Commonly seen with capacitive loads.
IP Rating
Ingress Protection rating per IEC 529.
Lateral Approach
The approach of a target perpendicular to the sensor reference axis.
A device or circuit that is operated by the energy output of another device such as a proximity sensor.
M Threading
ISO 68 Metric straight threading, designated as “Nominal Size” X “Pitch”, in mm. (Ex. M5X0.5)
Minimum Load Current
For 2-Wire sensors, the minimum load current defines the smallest specified current that a sensor requires for reliable operation.
The acronym for a European standards organization.
NAMUR Sensor
A 2-wire variable-resistance DC sensor whose operating characteristics conform to DIN 19 234. Requires a remote amplifier for operation. Typically used for intrinsically safe applications.
NEMA Rating
An enclosure rating per NEMA Standard 250.
No-Load Current
The current drawn by a DC proximity sensor from the power supply when the outputs are not connected to a load.
Nonembeddable (Nonshielded) Proximity Sensor
A sensor is nonembeddable when a specified free zone must be maintained around its sensing face in order not to influence the sensing characteristics.
Normally Closed (N.C.)
The output is OFF when the target is detected by the sensor.
Normally Open (N.O.)
The output is ON when the target is detected by the sensor.
NPN Output (Current Sinking)
A transistor output that switches the common or negative voltage to the load. Load is between sensor and positive supply voltage.
NPSM Threading
American National Standard Straight Pipe Thread for Free-Fitting Mechanical Parts.
NPT Threading
American National Standard Taper Pipe Thread.
Off-State (Leakage) Current
The current that flows through the load circuit when the sensor is in the OFF-state. Also known as leakage or residual current.
Operating Distance
A distance at which the target approaching the sensing face along the reference axis causes the output signal to change.
PG Threading
Steel conduit threading per German standard DIN 40 430.
PNP Output (Current Sourcing)
Transistor output that switches the positive voltage to the load. Load is between sensor and common.
Programmable Output
Sensor output whose N.O. or N.C. function can be selected by means of a jumper or specific terminal connection.
Radially Polarized Ring Magnet
A ring magnet whose poles are the inner and outer diameter rings.
Rated Operating Distance (Sn)
A conventional quantity used to designate the operating distance. It does not take into account either manufacturing tolerances or variations due to external conditions such as operating voltage and temperature.
Reference Axis
An axis perpendicular to the sensing face and passing through its center.
The deviation in the actual operating distance measured at a constant temperature and voltage over an 8-hour period. It is expressed as a percentage (%) of the rated operating distance (Sn).
Response Frequency
The maximum rate that the output can change in response to the input and still maintain linearity.
Response Time
The time required for the device switching element to respond after the target enters or exits the sensing zone.
Reverse Polarity Protection
Internal components that prevent damage to the sensor due to the incorrect connection of the power supply.
The alternating component remaining on a DC signal after rectifying, expressed in percentage of rated voltage.
Sensing Face
The surface of the proximity sensor through which the electromagnetic (or electrostatic) field emerges.
Short-Circuit Protection
The ability of a sensor to withstand a shorted condition (no current-limiting load connected) without damage.
Slew Rate
The rate of change of the output voltage with respect to a step change in input. A change in output of 0 to 10 volts at a slew rate of 1.25 V/ms would take 8 ms to slew to the new value.
Solid State
Pertains to devices using semiconductors instead of mechanical parts.
Static Output
A sensor output that stays energized as long as the target is present.
Switching Frequency
The maximum number of times per second that the sensor can change state (ON and OFF) under ideal conditions, usually expressed in Hertz (Hz).
Time-Delay Before Availability
The length of time after power is applied to the sensor before it is ready to operate correctly, expressed in milliseconds (ms).
Uprox Sensor
An inductive proximity sensor that detects all metals at the same range. Uprox sensors are inherently weld-field immune, operate over a wider temperature range and have a higher switching frequency than standard inductive sensors.
Uprox+ Sensor
Same basic characteristics as the Uprox Sensor, but with a redesigned multi coil system which provides increased sensing capabilities. Uprox+ also carries an IP68 environmental rating.
Weld-Field Immunity (WFI)
The ability of a sensor not to false-trigger in the presence of strong magnetic fields typically produced by resistance welders.
Wire-Break Protection
Results in the output being OFF on a DC sensor if either supply wire is broken.
