Sensore di prossimità capacitivo NKS...4300A series

cilindricoNAMURantideflagrante

General features: The capacitive sensors are used for detecting any material. Some materials, especial- ly 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, etc. 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% • Degree of protection according EN60529: IP67 • 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.
