SUNX GA-2D Photoelectric Proximity Sensor Switch

The SUNX GA-2D is a compact, separate-amplifier controller for SUNX GS/GA micro-size inductive proximity sensors. In a GA/GS system it functions as the signal conditioner and output driver, converting metal-detection events from the tiny sensor head into a dependable switch signal for your controller. This DC-powered amplifier accepts a 10–28 VDC supply and offers selectable NPN or PNP outputs, with an option to choose Light-ON or Dark-ON operation to match different electronics configurations. Marketed as an ultra-compact, amplifier-separated device, the GA-2D is a discontinued member of Panasonic’s SUNX GA/GS family, reflecting its role in space-constrained automation setups. Typical applications include precision metal-detection tasks on conveyors, packaging lines, presses, and other compact automation equipment where small GS/GA sensors monitor metal targets. When paired with a compatible SUNX sensor head, the GA-2D provides a complete, miniature sensing solution that combines a tiny detector with robust signal conditioning and versatile output options.
