Overview
The Baumer IFFM 20P17A3/S35L inductive proximity sensor is a flush-mounted rectangular sensor engineered for industrial automation applications requiring reliable metal detection. With an 8 mm nominal sensing distance and adjustable hysteresis (3–20% of Sr), this sensor delivers consistent switching performance at 500 Hz. The Baumer IFFM 20P17A3/S35L features a brass nickel-plated housing with PBT sensing face for durability in demanding environments.
