Accessories-Switches / sensors / position indicators-494-Magneto resistive - 1

MAGNETIC POSITION DETECTORS for "T" grooves magneto-resistive (MR) Detectors designed for use in explosive atmosphere zones 0-20, 1-21, 2-22, according to ATEX directive 2014/34/EU. Static non-contact proximity switch on air cylinders equipped with built-in permanent magnets. FUNCTIONAL DESCRIPTION When the permanent magnet which is mounted on the piston approaches the detector the magnetic field it generates causes the semiconductors’ resistors to change. This current variation increases the resistance and a switching signal is generated. DETECTOR CHARACTERISTICS ATEX APPROVAL 00569GB-2016/R01 Availability, design and specifications are subject to change without notice. All rights reserved. MAX. SWITCHING POWER SWITCHING VOLTAGE MAX.

MAGNETIC POSITION DETECTORS FOR " T " GROOVES - MAGNETO-RESISTIVE (MR) Cable 5 m long, 2 wires 0,14 mm2 stripped ends zones type approval certificate no. DEKRA BVS 10 ATEX 023 (1) Compatible barriers and interfaces ELECTRICAL PROTECTION • Output protected against short-circuit as long as the output current is restricted to 0.1 A. • Improper wire connection may prevent the detector from operating or even destroy it. • It is recommended to install a protection diode (mounted in parallel) on an inductive load in spite of the internal protection. 2 wires (for barrier protection) ● CONNECTION OF...
