Explanations of abbreviations in the type designation:
XXX YYZZZZ-WWW
XXX indicates the type of vibrator (three-phase or single-phase):
 NEA = single-phase alternating current
 NEG = 3-phase alternating current
 NES = 3-phase alternating current (stainless steel housing)
YY indicates the polarity:
 50 = 2 poles
 25 = 4 poles
 16 = 6 poles
 12 = 8 poles
ZZZZ indicates the centrifugal force in daN (Decanewton).
WWW indicates special features:
 K = 130°C PTC thermistor installed (standard from housing size 170
upwards)
 K2 = 120°C PTC thermistor installed
 TS = 130°C thermal protector with a normally closed (NC) switching
contact
 TS2 = 120°C thermal protector with a normally closed (NC) switching
contact
 H = 200-240V anti-condensation heater 0-50W
 H110 = 100-120V anti-condensation heater 0-50W
 HD = Fully encapsulated stator (heavy duty)
Suffix S behind the type designation = stainless steel housing
