Speed sensor MiniCoder GEL 247

Transcription

1 Speed sensor MiniCoder GEL 47 Flange assembly Technical information version 08.0 The MiniCoder family from Lenord + Bauer offers spacesaving 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 5 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 47 with its standard flange and unique design solves almost all installation problems. Main features module range from m = 1.0 to m = 3.5 measuring frequency from 0 to 5 khz integrated frequency divider (option) 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 +10 C high electromagnetic compatibility 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) All signals are also available in their inverted form.

D.P. = 5.4 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. Lenord +Bauer DS-47(08.0)

4 Installation drawing, EMC and ESD instructions Installation drawing EMC instructions To ensure the certified electromagnetic compatibility (EMC), the following installation instructions must be observed: Connect the screen at the end of the cable using a large contact surface, if possible. Keep all unscreened cables as short as possible. Keep grounding connections as short as possible using large cross-sections (low-induction grounding strip, ribbon cable) If the event of differences in potential between machine ground and ground of electronic circuit, appropriate measures must be taken to prevent equalizing currents from flowing via the cable shield (e.g. by providing for large-section equipotential bonding conductors or by using cables with separate double shielding where the shields are connected only at one end). Lay signal and control cables away from power lines. The power supply must correspond to installation class 0 or 1 in according with B.3 of EN of ESD instructions (Components sensitive to electrostatic discharge) As with any other electronic device, the MiniCoder must be connected with the necessary precautions against the risk of electrostatic discharge. Connector pins and connecting wires must not be touched without suitable discharge protection devices. Observe the instructions of EN Lenord +Bauer DS-47(08.0)

5 Supply voltage concept GEL 47 V 1. The MiniCoder supply is electrically isolated from the supply of the evaluation electronics.. The MiniCoder supply is not electrically isolated from the evalution electronics. (The screen is applied to the sensor and to the electronics and is interrupted in the conduit box) DS-47(08.0) Lenord +Bauer 5
