Model 120E
Vishay Spectrol
Incremental Optical Encoder Contactless Technology
(128 Pulses per Turn)
FEATURES
• Long life: 10 million revolutions minimum
(contactless)
• Cost effective: Elimination of A/D converters
RoHS
COMPLIANT
• Stainless steel shafts and nickel-plated bushing
in various lengths
• Stability: - 40 °C to + 65 °C operating temperature
