Description

• NAMUR SERIES • ATEX certified II 1GD for zone 0;20 • Cable output General features: These sensors are able to detect the presence of a metal blade into the slot. The switching point of the output happens when about the 70% of internal faces is covered by the blade. The special material of the housing allows the use without additional protections against electrostatic charges. Technical data: • Supply voltage according NAMUR: 7,7 ÷ 9 Vdc • Max ripple: 10% • Consumption at 8,2 V with Rx = 1000 Ω with metal: ≤ 1 mA without metal: ≥ 3 mA • Temperature range: - 20° ÷ + 60°C • Max thermal drift of sensing distance Sr : ± 10% • Repeat accuracy (R): 2% • Degree of protection according EN60529: IP67 • Cable conductor cross section: 0,14 mm2 in types DF3,5/… and DF5/… 0,75 mm2 in type DF6/… • Marking: II 1D Ex iaD 20 T80° C II 1G Ex ia IIC T6 • Certified IMQ 08 ATEX 010 • Electromagnetic compatibility (EMC) according to EN60947-5-2 • According to: EN60947-5-6/EN60079-0/EN60079-11/EN60079-26 • Shock and vibration resistance according to EN60068-2-27/EN60068-2-6 Safety parameters: • Vi max 13,5 V • Ii max: 60 mA • Ci max: 100 nF • Li max: 100 μH • Pi max: 200 mW These sensors must be used in conjunction with associated apparatus (See Sect. E) Use in hazardous area according to instruction manuals
