Product Description:
The 2110001000 encoder is manufactured by Danaher as part of the Dynapar Encoders series. This rotary feedback device translates shaft rotation into standardized electrical pulses, enabling motion controllers to monitor position and velocity in automated machinery. Its single-ended shaft fits common motor and lead-screw couplings used in motion systems. The keyed interface supports consistent coupling alignment when the encoder is connected to a rotating machine element. The unit is intended for industrial applications that require reliable incremental feedback for closed-loop monitoring.
The sensing electronics provide a resolution of 1000 PPR, producing square-wave signals that allow a connected controller to track incremental movement. The encoder has a minimum frequency response of 120 kHz and supports a maximum shaft speed of 6000 rpm. Its rugged open-collector output stage can sink up to 40 mA, while a maximum voltage rating of 30 VDC protects compatible downstream logic. The source circuit has a maximum supply current of 110 mA, limiting the electrical load placed on the connected power source. A 2.2 kΩ pull-up resistor establishes the idle output state for TTL or CMOS reception. The stainless steel shaft has a diameter of 3/8 inch, providing a durable interface for compatible couplings. Its momentary starting torque of 2.5 oz-in limits rotational drag as the shaft begins moving.
The encoder supports a radial load of 40 lb, while the housing can withstand an axial thrust of 30 lb without degrading pulse fidelity. The balanced rotor has a moment of inertia of 1.3 × 10-4 oz-in-s², supporting rapid acceleration and deceleration in servo systems. Its low rotor inertia helps the encoder follow speed changes without placing excessive resistance on the connected shaft. The single-ended keyed shaft provides positive engagement with a suitable coupling and reduces the possibility of rotational slippage. Electrical connection to a drive, counter, or motion controller is made through a six-pin MS connector. The connector consolidates the supply and output wiring in a defined interface, helping maintain secure signal connections in industrial equipment.
