Magnetic absolute encoders MARC645

Product catalog summary
Overview: The MARC645 is a magnetic single-turn absolute rotary encoder that operates on the Hall Effect principle. It is designed without a shaft and uses an external magnet-carrier mounted on the shaft of cooperating devices. It converts rotary motion into electrical signals, providing positional information for digital control systems or electric motor drivers.
Type Identification: The encoder is identified by its outlet type (PB for 0.5 m radial cable), shaft diameter (6 mm standard, 8 mm or 10 mm optional), supply voltage (+5 V), and encoder type (MARC645).
Mechanical Specifications: The encoder supports a maximum rotational speed of 10,000 min-1, vibration resistance of 10gn (10 to 2000 Hz), and shock resistance of 50gn (100 ms). It operates in temperatures from -25˚ to +80˚C, with a relative humidity of up to 95%. The device is protected to IP65 standards and weighs approximately 0.15 kg.
Electrical Specifications: The MARC645 provides 4096 positions per rotation (12 bits) and operates with a supply voltage of +5 ± 5% V and a maximum supply current of 50 mA. It outputs serial SSI signals in a single TTL gray code format.
Assembly Instructions: The encoder is mounted using three M3 screws on a 48 mm pitch circle diameter. The magnet-carrier must be positioned 6.65 ± 0.05 mm from the equipment's flange. Proper centering is achieved using the inner diameter 35H7 or outer diameter 55h7. The encoder is calibrated with its specific magnet-carrier, and using a different magnet may reduce accuracy.
Connection Elements: The connection cable includes various colored wires for different signals, including SSI CLOCK, DATA, and INC signals. The cable also includes a shield and power supply lines (GND and Vcc +5 V).
Ordering Information: When ordering, specify the encoder type, number of impulses per rotation, outlet type, quantity, delivery term, and any non-standard features. Accessories such as connecting cables and assembly tools can also be ordered.

Magnetic absolute encoders MARC645-1

Magnetic absolute encoders MARC645 MARC645 - without a shaft with external magnet-carrier The magnetic single turn absolute rotary encoders type MARC645 working on magnetic Hall Effect principle. The encoder converts rotary motion to electrical signals. Mechanically is designed without a shaft with external magnet-carrier which is mounted on the shaft cooperating devices. Electrical signals provide information of bilateral position of two mechanical parts, angle turn or rotary motion. A typical use is in conjunction with digital control system or drivers for control of the electric motors.

Magnetic absolute encoders MARC645-2

Description of connection elements MARC645 Assembly The encoders MARC645 are fixed to cooperative equipment by three screws M3 on the pitch circle diameter 48 mm. First the magnet-carrier is mounted on the shaft so that dimension between top of magnet-carrier and equipment’s flange must be 6,65 ± 0,05 mm. For this operation it is possible to use the assembly tool 62451631 which is possible to order as accessories. Centering of the encoder is by inner diameter 35H7 or outside diameter 55h7 . Note: The encoder is calibrated with its magnet-carrier and is paired with him. If another magnet or magnet-carrier...
