Capacitive proximity sensor NKS18/4600A

electromagneticcylindricalM30

NAMUR SERIES • ATEX certified II 1GD for zone 0;20 • Cable output • General features: The capacitive sensors are used for detecting any material. Some materials, especially if liquid or metallic, can be detected also through plastic or glass walls. They can be used for various applications: level control in storage bins or tanks; survey filling bottles; rain sensor; anti-vandalism tab; etc. The adjustment of sensing distance is made by a potentiometer at the back of the housing. Technical data: • Supply voltage according NAMUR: 7,7 ÷ 9 Vdc • Max ripple: 10% • Consumption at 8,2 V with Rx = 1000 Ω with metal: ≥ 3 mA without metal: ≤ 1 mA • Temperature range: - 20° ÷ + 60°C • Max thermal drift of sensing distance Sr : ± 20% • Repeat accuracy (R): 4% • Cable conductor cross section: 0,75 mm2 • 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.
