6	Output Signals
7	GEL247 Axial or radial cable outlet - Single-track square-wave signals - Two 90°-shifted square-wave signals for direction sensing - Two signals with potential separation - All signals available in their inverted form (RS485) Over 250 customer specific variants available
8	Speed Sensors for Aluminium Targets
9	Latest Developments
10	Sensor for explosion hazard areas Speed and position measurement in machines and motors Speed and position measurement in explosion hazard areas Position measurement on piston rods
11	Compact Speed Sensors
12	High Resolution Precision Encoders
13	High Resolution Precision Encoders High number of pulses per revolution Integral toothed wheel, m=0.3, z=256 separate interpolation for z=1024 Integrated bearings Integrated coupling in the hollow shaft Easy installation
14	High Resolution Encoders
15	Multi-channel encoders Frequently used when several independent signals are required and pick-up locations are limited. For example: Traction control, wheel slip prevention, vehicle speed, event recorder, door control, signalling, etc Designed for axle-end mounting Extreme vibration resistant Magnetic sensors Robust and resistant to contamination by oil, dirt and moisture
16	Customers We work together with the following manufacturers and rail industry suppliers : Bombardier Transportation Siemens Transportation Systems Alstom Transport Vossloh-Kiepe Elin Hanning + Kahl Knorr Bremse VEM Skoda
17	Partial Customer List:
18	Problems with competitors’ speed sensors Increased cost due to short life resulting in frequent maintenance Long delivery time of replacement parts (eg. Knorr Bremse) High cost of replacement parts Some suppliers do not exist anymore
19	Why Lenord + Bauer L+B = Reliable and Competent partner Focussed on speed sensors Modern designs, upgraded continuously Excellent references Reliable speed sensors, robust and durable Short delivery times
20	Competition Krauss-Maffei Mannesmann-Rexroth Knorr-Bremse SAB-WABCO Jaquet Noris Deuta Honeywell (Electrocorp)
21	References: Locomotives BR 145, BR 185 State-of-the-art in railway technology Why Lenord + Bauer? Tailor-made development together with the customer Superior performance Field experience with BR 145: BR 185 is also equipped with GEL 295
22	References: Encoder 293 in USA San Francisco (BART) Atlanta (MARTA) New York (NYCT) Why Lenord + Bauer? Outstanding performance of GEL 293 In-depth field trials made clear that the encoders from Lenord + Bauer are the best suited for this application Simplified mounting due to integrated coupling.
23	References: Kiruna, Sweden Heavy-duty locomotive for ore railway. Very harsh environment Why Lenord +Bauer? Multi-channel encoder required for motor mounting (Axle mounting not possible due to harsh environment) Custom encoder developed with 2 outputs, high and medium resolution in one housing
24	References: Incentro Three different GEL 247 Why Lenord + Bauer? Short housing length with lateral cable outlet version for spur wheels saves additional toothed wheel GEL 247 with divider: brake control from the motor axle
