| Device options |
- Redundant incremental output - S: Electronic overspeed switch with two mutually independent, programmable switching points. - FOC: As an alternative to conventional signal transmissions via copper cables it is also possible to transmit encoder signals via a fiber optic cable. - N: Mechanically fixed reference pulse (N), one square-wave pulse per revolution, with inverted signal. - 2F: Twice as many basic track pulses by combining the 0° and 90° tracks. - B: Rapid direction of rotation sensing at each edge of 0° and 90° tracks. - B2: Rapid direction of rotation sensing at each edge of 0° and 90° tracks; additional standstill detection. - B3: Direction of rotation dependent output signals. This option supports counter cards with separate UP/DOWN pulse inputs. Basic track signals are issued at optional output 1 when rotation is clockwise and at optional output 2 when rotation is counterclockwise. - SH: 1 Vpp signals sin, cos, reference pulse. Status as HTL signal; all signals each with respective inverted signals. - ST: 1 Vpp signals sin, cos, reference pulse. Status as TTL signal; all signals each with respective inverted signals. |

| The all-rounders for speed measurement | |
| The incremental encoder FG 40 (solid shaft) / FGH (J) 40 (hollow shaft) can be deployed in a wide variety of applications to measure the speed of standard, auxiliary and secondary drives in steel and rolling mills, in mining operations as well as in ports and crane systems. When attaching with an isolated coupling (solid shaft) or with optionally available isolating hybrid bearings (hollow shaft) they protect the drivetrain against damaging shaft currents. They offer a high signal quality and, if required, a high pulse rate for dynamic feed-back control across the entire speed range. In particular the rugged foot construction facilitates simple attachment of further encoders at the second shaft end. | |
