Panasonic GX-H8 is a rectangular, top sensing GX-8 type inductive proximity sensor from the GX-F/H series. The maximum operation distance (Sn) is 2.5 mm ±8 % and the stable sensing range is 0 to 2.1 mm, referenced to an iron sheet of 15 × 15 × t 1 mm. Repeatability is 0.04 mm or less, hysteresis 20 % or less and maximum response frequency 500 Hz. The PBT enclosure has a polycarbonate/polyester indicator part; net weight is about 20 g.
Supply is 12 to 24 V DC (+10/−15 %, ripple 10 % or less); current consumption is 15 mA or less. GX-H8A is the NPN normally open model; B means normally closed, -P PNP output and I the different-frequency type. The output carries up to 100 mA with 2 V or less residual voltage and has no short-circuit protection. Protection is IP68 and IP68G; shock resistance is 10,000 m/s². The 1 m oil-, heat- and cold-resistant cable can be extended to 100 m in total with 0.3 mm² or thicker cable.
