2212700240 by Danaher

The Danaher 2212700240 encoder from the Dynapar Encoders series delivers precise incremental optical feedback for demanding industrial automation applications. This robust device operates across a resolution range of 1 to 2500 PPR, offering flexible pulse-per-revolution selections for a wide variety of motion control tasks. Housed in a rugged aluminum housing and weighing 10 lbs, it provides mechanical resilience and stable performance even under high vibration or shock. Its two-channel phased quadrature output (AB) with optional index ensures accurate bi-directional detection and speed measurement. Integrated within is a TC1428 Differential Line Driver capable of sourcing and sinking 40 mA for reliable signal transmission over long cable runs or in high-noise environments.

Electrical requirements are modest, accepting 5 to 15 VDC input at a maximum of 115 mA, plus any additional load current. The encoder supports a frequency response of 50 kHz, enabling fast response to rapid shaft rotations. Mechanical design accommodates a 5/8 inch nominal shaft and safely handles radial loads up to 45 lbs and axial loads up to 15 lbs. A starting torque of 15 oz-in ensures smooth initial movement, while the rotor inertia of 285 gm-cm² maintains stable acceleration profiles. Maximum shaft speed is rated at 3600 RPM, making the unit suitable for high-speed shaft monitoring. Connections are achieved via a 10-pin MS3106A-18-1S mating connector, ensuring robust and secure electrical engagement.

Under operational conditions, the 2212700240 provides consistent quadrature signaling with A leads B for CW rotation, guaranteeing correct phase sense for motion controllers. The durable optical incrementing element maintains output integrity over extended service life, with no requirement for routine recalibration or maintenance. Signal format includes two channels plus index for exact homing operations, supporting both open-loop and closed-loop control systems. The encoder’s aluminum construction and sealed internal components deliver enhanced environmental tolerance, resisting dust ingress and mild moisture exposure common in factory settings. Its combination of low starting torque, high load capacity, and fast frequency response optimizes dynamic performance for varying load conditions.

System integration is simplified through direct compatibility with standard industrial controllers, PLCs, and motion drives that accept differential line inputs. The encoder’s part_number and form factor match industry-standard mounting footprints, minimizing mechanical redesign efforts. It is ideally suited for conveyor systems, rotary indexing tables, robotic axis feedback, and packaging machinery requiring high-resolution positional feedback. Backed by the reputable manufacturer in the series, this Dynapar encoder delivers reliable, high-precision performance in diverse automated industrial applications.
