Description
Autonics Original PR12-4DP DC10~30 4mm M12 Inductive Proximity Sensor PNP-NO (Unshielded)
Looking for a reliable proximity switch sensor that delivers high performance in industrial environments? The Autonics PR12-4DP is engineered for exactly that. This pnp sensor supports DC10-30 V input, has an M12 thread size and a 4 mm detection range — making it a top pick for demanding machine-control applications. Moreover, the pnp sensor price is very competitive given its premium feature set.
This inductive proximity switch sensor utilises an electromagnetic field to detect metallic targets without contact. In contrast to capacitive sensors—which detect dielectric or conductive materials—this model is optimised for metal objects only. Thanks to built-in sensitivity adjustment and enhanced noise immunity, it stands out among similar pnp sensors.
With features such as PNP-NO output and non-flush (unshielded) installation, this pnp sensor offers strong versatility. Also, the robust design supports durability and reliability: maximum output current 200 mA, setting distance 0–2.8 mm, and a response frequency of 500 Hz. Use this where you need fast switching, high noise immunity and a compact M12 form factor.
