Speed Sensor GEL 2476
General
- Application approved speed sensor based on magnetic measurement principle
- Maintenance- and wear-free operation due to non-contact measurement of rotation
- Suitable for ferromagnetic target wheels
- Safe detection of slow rotation from 0 Hz without pulse loss and for high-speed rotation up to 25 kHz
- Two channels shifted by 90° provide the direction of rotation
- Robust and compact stainless steel housing suitable for harsh application
- Constant duty output signals
- Customized cable fittings
Features
- Modul target wheel 1.00 to 3.50
- Measuring range 0 Hz to 25 kHz
- Temperature range -40 to +120°C
- rotection class IP 68
- Type testing according to EN 50155
Advantages
- Current output signals unsusceptible to electromagnetic disturbances
- Cable break monitoring by current output or voltage output with standstill voltage
- Maintenance-free due to significant measuring distance (air gap up to 3 mm)
- 45° mounting position possible
Fields of application
- Rail vehicles
- Traction control
- Anti-slip
- Anti-skid - Automation
- Measurement of speed and positions at gears,motors and roller
