The Panasonic GX-H12A-P Inductive Proximity Sensor features a maximum operation distance of 4.0 mm (0.158 in) with an 8% tolerance and a stable sensing range of 0 to 3.3 mm (0 to 0.130 in). It is designed to detect standard sensing objects such as iron sheets measuring 20 × 20 × 1 mm (0.787 × 0.787 × 0.039 in). The sensor boasts a high repeatability of 0.04 mm (0.002 in) or less along both the sensing axis and perpendicular to it, ensuring precise detection even in varying ambient conditions.
The Panasonic GX-H12A-P Inductive Proximity Sensor operates on a supply voltage range of 12 to 24 V DC with a current consumption of 15 mA or less. It utilizes a PNP open-collector transistor output, capable of a maximum sink current of 100 mA and applied voltage of 30 V DC or less, with a residual voltage of 2 V or less at 100 mA sink current. The sensor’s output operation is normally open, with a maximum response frequency of 500 Hz. An orange LED indicator provides visual feedback when the output is ON, enhancing operational visibility.
The GX-H12A-P is built for harsh environments with IP68 (IEC) and IP68g (JEM) ratings, and it operates within -25 to +70 °C (-13 to +158 °F). It resists vibrations (10 to 500 Hz, 3 mm amplitude, up to 20 G) and shocks (10,000 m/s², approx. 1,000 G). Made of durable PBT and polyester, it includes a 1 m (3.281 ft) oil, heat, and cold-resistant cabtyre cable, extendable to 100 m (328.084 ft). Compliant with EMC and RoHS Directives, it ensures high quality and safety standards.
