S

Sampling frequency
Number of signal periods per second. The maximum sampling frequency limits the speed of incremental measuring systems.

Scaling
For programmable absolute shaft encoders the encoder actual value is multiplied by a scaling factor. Thus the resolution (increments per measuring distance or increments per revolution) is adaptable to the respective application.

SDO
Service data object (in CAN networks)

Sense
The Sense lines (Sense VCC and Sense GND) enable measurement of the factual encoder voltage without adulteration by voltage drop due to supply current and cable resistivity. With that e.g. supply voltage can automatically be adjusted.

Sensor supply
Voltage supplied to feed a pulse generator by the counter.

Set mode
See operating mode

Set value
See preset value

Setting value
The value to which a counter will be set. Two types of setting values exist: one-time and repeatable setting values.
One-time: The count is set to a specific value. This value is not stored and cannot be recalled.
Repeatable: The counter is set to a specific value (e.g. preset value). This value can be recalled at all times.

Shock stability
Hengstler counters are shock-tested according to IEC 68 Section 2-27
Test example:
impulsive shocks to test object from 6 directions with an acceleration of 500 m/s2 and a duration of 6 ms per direction each.

Spark quenching
For electromechanical counters
with diodes For DC counters and counting rates of up to 10 Hz on counter coils and resetting solenoids. The diode used should withstand a peak inverse voltage of approx. 5x rated voltage.
with RC combinations For DC counters and counting rates of > 10 Hz; for AC counters if the counter is triggered with sensitive contacts.

SSI
Synchronous-serial Interface; standardized interface for serial data transfer

Static behavior
The counter functions are carried out as long as the signal is present.
