Magnetic absolute encoders MARC690 and 695

Product catalog summary
Overview: The MARC690 and MARC695 are magnetic absolute encoders designed for precision applications such as tool head positioning and automation. They operate on the magnetic Hall Effect principle and provide 6-bit output signals, customizable to 512 positions based on customer specifications.
Specifications:
  • Rotational Speed: Up to 5000 min-1
  • Angular Acceleration: Up to 40000 rad.s-2
  • Moment of Inertia: Max 5 g.cm2 ± 10%
  • Vibration Resistance: 10gn (10 to 2000 Hz)
  • Shock Resistance: Max 50gn (100 ms)
  • Shaft Loads: Axial max 10 N, Radial max 20 N
  • Operating Temperature: -25˚ to +80˚ C
  • Humidity: Max 95% relative / 40 g.m-3 absolute
  • Protection: IP65
  • Weight: Approximately 0.15 kg
  • Cable Length: Max 50 m
Electrical Characteristics:
  • Supply Voltage: MARC690: +10 to +30 V, MARC695: +5 V ± 5%
  • Supply Current: MARC690: 60 mA @ 30V, MARC695: 50 mA
  • Output Frequency: Max 30 kHz
  • Output Current: MARC690: ±25 mA, MARC695: ±20 mA
Connection Details: The encoders are connected using a color-coded cable system. Key connections include:
  • Blue: GND
  • Brown: Supply Voltage (MARC690: +10 to +30 V, MARC695: +5 V)
  • White to Black: Bit 0 to Bit 5
Installation and Ordering: The encoders are mounted using a servo groove or clamping flange, with centering determined by a 25h7 diameter fit. It is crucial to avoid exceeding the maximum radial or axial shaft load. For temperatures below -5°C, cables must be fixed. Orders should specify encoder type, number of impulses per rotation, outlet, and any non-standard features. Accessories such as connecting cables and couplings are available.

Magnetic absolute encoders MARC690 and 695-2

Description of connection elements MARC690 and 695 Assembly The encoders MARC690 and MARC695 are fixed into the equipment by servo groowe or clamping flange. Centering of encoder is determined by mat fits diameter 25h7. 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 temperature is less then -5°C cable must be fixed. How to order? Please indicate encoder type, number of impulses per rotation, outlet, number of pieces,...
