It has a high performance of 3.3 kHz response frequency. Panasonic GA-311/GH compact inductive proximity sensors are ideal for sensing objects moving at high speeds. The lineup includes 5 different models, from an ultracompact 2.8 mm 0.110 in diameter type to a spatterresistant type. Furthermore, all except for the GH-2SE are IP67G oil-resistant models so that they can be used with confidence even in adverse environments. They all have the same form as the FX-300 series of fiber sensors. The quick-connection cables are also of the same shape, so that fiber sensors and laser sensors can all be used together and less power supply wiring is required. The connection between the sensor head and the amplifier is made using a quick-connection connector. Past troublesome wiring connections using a screwdriver are no longer necessary.
