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
• Variability: Cable and printed circuit terminations available
The Model 120E is a light-duty optical encoder that can be manually. This unique device outputs two square waves at a maximum
rate of 128 pulses in quadrature with other resolutions as low as 10 pulses available. Typical applications includes Motion sensing
and control, Motor control, Flow control, Low-to-high input for test and measurement, Medical instrumentation, Robotics and
Computer Peripherals.
