Turck BI20-CA40-ADZ30X2-B1131/S34 Inductive Proximity Sensor

The Turck BI20-CA40-ADZ30X2-B1131/S34 inductive proximity sensor delivers a 20 mm sensing distance for non-contact detection of metallic targets in industrial automation, making it suitable for long-range position sensing on conveyors, packaging machines, pallet handling equipment, and automated production lines. This 2‑wire normally open device operates from 20–250 VAC or 10–300 VDC and can switch up to 400 mA at a maximum switching frequency of 20 Hz, with a 7/8" male connector for rugged field connections. The rectangular housing is made from glass fiber reinforced plastic and is rated IP67, designed for surface mounting with adjustable orientation to fit tight or variable mounting spaces. The sensor supports flush-mount installation and is intended for applications requiring reliable, non-contact metal object detection and PLC feedback in industrial environments. Product identifiers include the manufacturer part number BI20-CA40-ADZ30X2-B1131/S34 and an identification number of 185677.
