Magnetic absolute encoders MARC605 and 615

Product catalog summary
Overview: The document provides technical specifications and operational guidelines for the MARC605 and MARC615 magnetic absolute encoders, manufactured by LARM a.s. These encoders are designed for converting rotary motion into electrical signals using the magnetic Hall Effect principle.
Mechanical Specifications:
  • MARC605 features a synchro flange, while MARC615 has a clamping flange. Both have a shaft diameter of 6 mm.
  • Maximum rotational speed is 10,000 min-1 with an angular acceleration of 40,000 rad.s-2.
  • Moment of inertia is 10 g.cm2 ± 10%.
  • Vibration resistance is 10gn (10 to 2000 Hz) and shock resistance is 50gn (100 ms).
  • Axial and radial shaft loads are 10 N and 20 N respectively.
  • Operating temperature ranges from -25˚C to +80˚C, with a humidity tolerance of up to 95% relative or 40g.m-3 absolute.
  • Encoders are protected to IP65 standards and weigh approximately 0.15 kg.
Electrical Specifications:
  • Supply voltage is +5V ± 5% with a maximum current of 50 mA.
  • Output signals include parallel TTL binary code and serial SSI signals with various configurations (9 to 13 bits).
  • Clock period ranges from 250 to 2xTm µs, with specific timings for clock high, clock low, and monoflop time.
Installation and Assembly:
  • MARC605 is installed using 4xM3 screws on a 26 mm diameter or groove, while MARC615 uses 2xM3 screws on a 22 mm diameter.
  • Proper alignment and load management are crucial to avoid exceeding maximum shaft loads.
  • Homokinetic diaphragm couplings are recommended for optimal performance.
Ordering Information:
  • Specify encoder type, number of impulses per rotation, outlet, number of pieces, delivery term, and any non-standard features.
  • Accessories such as connecting cables and couplings can be ordered separately.
Connection Elements:
  • Color-coded connection cables are provided for various signals, including SSI CLOCK, DATA, and INC signals.
  • Ground and power connections are marked in black, brown, and red respectively.

Magnetic absolute encoders MARC605 and 615-1

Magnetic absolute encoders MARC605 and 615 MARC605 - synchro flange, external diameter of the shaft 6 mm MARC615 - clamping flange, external diameter of the shaft 6 mm The magnetic single turn absolute rotary encoders type MARC605 and MARC615 working on magnetic Hall Effect principle. The encoder converts rotary motion to electrical signals. 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 MARC605 and 615-2

Description of connection elements MARC605 and 615 The encoders MARC605 are installed into appropriate equipment using 4xM3 screws on dia. 26 mm or a groove. The position of the shaft is explicitly determined by a fitted diameter of 33h7. The encoders MARC61 5 are fixed into the equipment by 2xM3 screws on dia. 22,0 mm. Centering of encoder is determined by mat fits diameter 15h7. The connection has to be constructed so as to avoid exceeding the maximum radial or axial shaft load permitted. It is necessary to keep alignment connection. It is recommended to use suitable homokinetic diaphragm couplings. When...
