Not for New Design
Incremental Resistive Encoder
(32 to 128 Pulses per Turn)
This Model DE2 is only for maintenance purposes. It is not
recommended for new designs and will be obsolete in a near
future.
FEATURES
• Patented Silver-in-Glass^TM switching element technology
• Two channel quadrature output
• Optional index pulse
• 32 pulses per revolution (can be resolved to 128
increments per revolution)
• Additional pulses per revolution available (consult factory)
• Internal active debounce circuitry provides clean, high
level outputs with CMOS or TTL logic
