AutomationDirect AK1-AP-4H Inductive Proximity Sensor

AutomationDirect's AK1-AP-4H is a tubular inductive proximity sensor with an 18 mm diameter and 64 mm long nickel-plated brass housing, designed for non-flush mounting and detecting metal targets at a 12 mm sensing distance. It operates from 10–30 VDC and provides a 3-wire PNP normally open output through a 4-pin M12 quick-disconnect, offering reliable switching at up to 300 Hz in industrial environments. Built to withstand harsh conditions, the AK1-AP-4H is rated IP67 for dust and moisture resistance and supports standard factory automation cycles, with an operating temperature range from -25°C to 70°C. The unit is part of AutomationDirect's Micro Detectors line, featuring a tubular form factor that suits inline sensing on conveyors, machines, or guards without flush mounting, ensuring quick integration into control circuits with straightforward DC supply and rugged build.
