Description

■ Application approved speed sensor based on magneticmeasurement principle

■ Maintenance- and wear-free operation due to contactlessmeasurement of rotation

■ Scans measuring scales made of ferromagnetic materials,e.g. toothed wheels

■ Wide measuring range for safe detection of slow rotationwithout pulse loss and for high-speed rotation

■ Two channels shifted by 90° provide the direction of rotation■ Robust and compact stainless steel housing suitable for

harsh application■ Constant duty output signals■ Customised cable fittings

Features

■ Module of measuring scale: 1.0 to 3.5■ Temperature range: -40 °C to +120 °C■ Degree of protection: IP 68■ In accordance with DIN EN 50155:2008-03

Advantages

■ Low lifecycle costs for the vehicle operator due to high relia-bility

■ Place-saving sensor in a compact design

Fields of application

■ Rail vehicles- Traction control- Anti-slip- Motor speed
