Speed sensor MiniCoder GEL 247 - THOMAS

Speed sensor MiniCoder GEL 247. Flange assembly Technical information version The MiniCoder family from Lenord + Bauer offers space- saving solutions for the contactless measurement of rotational movements with direction sensing. The MiniCoders operate from 0 Hz on for the detection of very slow movements without pulse loss and up to 25 kHz for the direct integration into high- Speed motors and machines. The high interference immunity ensures reliable function even under adverse operating conditions. This MiniCoder GEL 247 with its standard flange and unique design solves almost all installation problems. Main features module range from m = to m = measuring frequency from 0 to 25 kHz integrated frequency divider (option).

1 Speed sensor MiniCoder GEL 247. Flange assembly Technical information version The MiniCoder family from Lenord + Bauer offers space- saving solutions for the contactless measurement of rotational movements with direction sensing. The MiniCoders operate from 0 Hz on for the detection of very slow movements without pulse loss and up to 25 kHz for the direct integration into high- Speed motors and machines. The high interference immunity ensures reliable function even under adverse operating conditions. This MiniCoder GEL 247 with its standard flange and unique design solves almost all installation problems. Main features module range from m = to m = measuring frequency from 0 to 25 kHz integrated frequency divider (option).

2 Simple flange-mounting without adjustment robust stainless steel casing straight or side cable outlet customized cable fittings very high protection class IP 68. wide temperature range -40 C to +120 C. high electromagnetic compatibility the Speed sensor complies with the requirements of EN 50155. Fields of application rail vehicles - traction control - wheel slip prevention - engine Speed machine automation - measurement of Speed and position in machines and motors Output signals signal forms: - single-track square-wave signals - two 90 -shifted square-wave signals for direction sensing - two signals with potential separation can be supplied with different voltages (option).

Reduced air gap for modules and (air gap from .. mm). 2). Tolerance dependent on the module of the toothed wheel. * Conversion from module (M) to diametric pitch ( ) = M. Frequency Divider This option can be used to reduce the signal output frequency by a given factor. This is useful for applications in which the detection of a pre-specified toothed wheel would otherwise produce an output frequency too high for the control electronics.
