Time inductive sensors KSO, KSL, KSR, KSF and KSFL represent an integrated series of inductive sensors with various options of time component processing.
The output periphery of all types are supplied with protection against confusion of input wires, against inductive supply surges and against overload and short circuit.
Each type is supplied with connector or a cable, while the time constant (T1) can be fixed or variable in a certain range. In this case, an adjustable trimmer with 20 revolutions is hidden under the removable connector K, or is placed in the label (for versions with cable or with E connector).
The producer recommends the following basic values for adjustment (T1):
a) 0,01-0,2s (5-100 Hz, 300-6000 RPM)
b) 0,1-2s (0,5-10 Hz, 30-600 RPM)
c) 0,5-10s (0,1-2 Hz, 6-120 RPM)
d) 5-100s (0,01-0,2 Hz, 0,6-12 RPM)
Of course it is possible to order other ranges after consultation with the producer.
The variable constants (T1) requested by the customer can range in the bandwidth 1ms to 60s, however, the specific time range should basically not exceed one decade.
If requested by the customer, every time sensor may be equipped with the so-called DELAY function, which defines sensor connection of supply voltage, when the sensor is asynchronously connected for time T1 (in order “character H“), or disconnected for time T1 (“character L“), regardless of any movement of a detected part of the machine. This function is used to disable sensor output, e.g. when waiting for engine startup, etc.
Length of this function must always exceed maximum possible adjustable time constant (T1). Therefore, if we want time sensor with variable constant (T1) 0.5-10 s, we have to consider the DELAY function in the range >10 s.
All the mentioned types of sensors are produced with a PNP as well as NPN output for direct-current (DC) supply, and in a two-wire version for 230 V AC.
