High Temperature 125°C Two Channel Optical Incremental Encoder Modules Technical Data HEDT-9000 HEDT-9100 Features • High Performance • High Resolution • Low Cost • Easy to Mount • No Signal Adjustment Required • Insensitive to Radial and Axial Play • Small Size • -40°C to 125°C Operating Temperature • Two Channel Quadrature Output • TTL Compatible • Single 5 V Supply Description The HEDT-9000 and the HEDT9100 series are high performance, low cost, optical incremental encoder modules that operate to 125°C. When used with a codewheel, these modules detect rotary position. The modules consist of a lensed (LED) source and a detector IC enclosed in a small C-shaped plastic package. Due to a highly collimated light source and unique photodetector array, these modules are extremely tolerant to mounting misalignment. The two channel digital outputs and the single 5 V supply input are accessed through five 0.025 inch square pins located on 0.1 inch centers. Package Dimensions CH. B VCC CH. A N.C.

For the HEDT-9100, standard resolutions between 96 CPR and 512 CPR are available for use with a HEDS-5120 codewheel or equivalent. Block Diagram Applications The HEDT-9000 and 9100 provide sophisticated motion detection at a low cost, at temperatures to 125°C, making them ideal for high volume automotive applications. Note: Agilent Technologies encoders are not recommended for use in safety critical applications. Eg. ABS braking systems, power steering, life support systems and critical care medical equipment. Please contact sales representative if more clarification is needed. Output Waveforms Theory of Operation The HEDT-9000 and 9100 are Cshaped emitter/detector modules. Coupled with a codewheel, they translate the rotary motion of a shaft into a two-channel digital output. As seen in the block diagram, each module contains a single Light Emitting Diode (LED) as its light source. The light is collimated into a parallel beam by means of a single polyetherimide lens located directly over the LED. Opposite the emitter is the integrated detector circuit. This IC consists of multiple sets of photodetectors and the signal processing circuitry necessary to product the digital waveforms. The codewheel rotates between the emitter and detector, causing the light beam to be interrupted by the pattern of spaces and bars on the codewheel. The photodiodes which detect these interruptions are arranged in a pattern that corresponds to the radius and design of the codewheel. These detectors are also spaced such that a light period on one pair of detectors corresponds to a dark period on the adjacent pair of detectors. The photodiode outputs are then fed through the signal processing circuitry resulting in A, A, B, and B. Two comparators receive these signals and produce the final outputs for channels A and B. Due to this integrated phasing technique, the digital output of channel A is in quadrature with that of channel B (90 degrees out of phase). Definitions Count (N): The number of bar and window pairs or counts per revolution (CPR) of the codewheel. 3 Pulse Width (P): The number of electrical degrees that an output is high during 1 cycle. This value is nominally 180°e or 1/2 cycle. Pulse Width Error (∆ P): The deviation, in electrical degrees of the pulse width from its ideal value of 180°e. State Width (S): The number of electrical degrees between a transition in the output of channel A and the neighboring transition in the output of channel B. There are 4 states per cycle, each nominally 90°e. State Width Error (∆ S): The deviation, in electrical degrees, of each state width from its ideal value of 90°e.

This value is nominally 90°e for quadrature output. Phase Error (∆φ): The deviation of the phase from its ideal value of 90°e. Direction of Rotation: When the codewheel rotates in the direction of the arrow on top of the module, channel A will lead channel B. If the codewheel rotates in the opposite direction, channel B will lead channel A. Optical Radius (Rop ): The distance from the codewheel’s center of rotation to the optical center (O.C.) of the encoder module.
