Automation Direct PY3-AN-1A Inductive Proximity Switch

PY3-AN-1A is a tubular inductive proximity switch from AutomationDirect, featuring a Ø3 mm sensor element in a stainless-steel housing with a 22 mm body and a 2 m axial PVC cable. It provides a normally open (NO) NPN output in a 3‑wire configuration and operates on 10–30 VDC with a load current rating up to 100 mA. No‑load current is ≤10 mA, voltage drop ≤2.0 V, and it switches at up to 5 kHz, with a nominal sensing distance of 0.6 mm. The device is IP67 protected and uses a polyester sensing face; it weighs about 23 g. An LED indicator illuminates when the output is energized, and the sensor includes reverse polarity protection and short‑circuit protection (auto‑resets after overload).
