DATA SHEET RE16D01_02 Issue 02, 4th April 2023 RE16 / RM16 Super Small Incremental and Absolute Encoders SUPER SMALL SIZE The RE16 and RM16 are compact, sealed, miniature, high speed rotary magnetic encoders designed for use in space-constrained applications. The encoder body is only 16 mm in diameter in an aluminium housing. HIGH OPERATING SPEED HIGH ACCURACY Features and benefits ⯈ Super small size – 16 mm diameter body ⯈ Industry standard incremental, SSI and linear voltage output formats ⯈ 5 V power supply versions ⯈ High speed operation up to 30,000 rpm INDUSTRIAL AUTOMATION

General information The rotation of the magnetic actuator is read and processed by a custom encoder chip within the body to provide incremental, SSI or linear voltage outputs. The encoder chips process the received signals with up to 12 bit resolution (4,096 counts per revolution) at high operating speeds. Designed for direct integration into high-volume OEM applications, the RE16/RM16 encoders can be used in a wide range of applications, including motor control and industrial automation. Encoder body Encoder system Product range RE16/RM16 I Incremental with 8 to 1,024 pulses per revolution (32...

Output types Incremental, single ended RE16/RM16 ID Specifications Power supply Current consumption Output signals There are three signals for the incremental output: A, B and Z. Signals A and B are quadrature signals, shifted by 90°, and signal Z is a reference mark. The reference mark signal is produced once per revolution. The width of the Z pulse is 1/4 of the quadrature signal period and it is synchronised with the A and B signals. The position of the reference mark is at zero. The graph on the right shows the timing diagram of A, B and Z signals with clockwise rotation of the magnet. B...

Synchro serial interface (SSI) RE16/RM16 SC Specifications Power supply Current consumption Clock frequency Serial output data is available in up to 12 bit natural binary code through the SSI protocol. With the clockwise magnet rotation, the value of the output data increases. Parameter Clock period Clock high Monoflop time Timing diagram for SSI output The controller interrogates the encoder for its positional value by sending a pulse train to the Clock input. The Clock signal must always start from high. The first high/low transition (point 1) stores the current position data in a parallel/serial...

Linear voltage, single ended RE16/RM16 Vx Specifications Power supply Current consumption Output voltage Output load The digital relative angular position information is converted into linear voltage with a built-in 10 bit D/A converter. The linear output voltage swing ranges from 0 V and Vdd (5 V). The number of periods within one revolution (Nperiod) can be 1, 2, 4 or 8, representing one full swing over an angle (φperiod) of 360°, 180°, 90° or 45° respectively. The signal is made up of steps which represent the angular movement needed to register a change in the position (φstep) and the resulting...
