Product Description:

The 2212701230 incremental rotary encoder is built by Danaher within the Dynapar Encoders series. It monitors angular movement and relays position data to drive controllers, servo loops, or PLC high-speed counters used in industrial automation. Electrical and mechanical connections are provided through a circular military-style 7-pin MS3106A-16S-1S connector, which carries the supply and differential signal pairs in a compact shell that resists vibration.

A native resolution of 1270 PPR divides one revolution into finely spaced quadrature pulses, supporting precise linear or rotary indexing. Logic transitions are delivered at an output level of 5 V, allowing direct connection to TTL-compatible inputs without external signal conditioning. The code disk may spin at up to 6,000 rpm before pulse integrity is compromised. The emitter-detector electronics sustain a minimum data rate of 120 kHz, keeping the pulse frequency within the response range of most high-speed counters. This combination supports accurate motion tracking during rapid shaft rotation and repeated positioning cycles in automated machinery.

The LED and line driver draw a maximum current of 110 mA, while each differential pair can sink or source up to 40 mA per channel, enabling long cable runs without significant signal loss. The encoder uses differential output circuitry to improve resistance to electrical noise in industrial environments. Its quadrature pattern supports bidirectional motion detection, giving controllers real-time direction information without additional sensors. Mechanical starting torque is limited to 2.5 oz-in, and the rotor has a moment of inertia of 1.3 × 10⁻⁴ oz-in-s², so acceleration loads on the driving shaft remain low. The 3/8-inch solid shaft connects through a standard collet or flexible coupling. Because the encoder has no index output, systems that require a once-per-revolution reference must generate that signal externally.
