Turck BI2-512-AZ31X Inductive Proximity Switch

Turck BI2-512-AZ31X Inductive Proximity Switch is a shielded inductive sensor for non-contact detection of metal objects and machine-position sensing in industrial automation. It features a 2 mm sensing distance with a normally open (NO) output and a 2-wire AC/DC configuration, supporting 20-250 VAC or 10-300 VDC supply and a maximum load current of 100 mA (minimum load 5 mA). The compact rectangular housing is made of reinforced PBT-GF30 plastic, flush-mountable with an integral cable, and rated IP67 for harsh environments, operating from -25°C to +70°C with an inrush current up to 1 A and an LED status indicator. Typical applications include packaging machinery, conveyors, transfer systems, and PLC-controlled production lines for part presence detection, end-of-travel monitoring, machine positioning, and product verification. Common Turck replacements in this family include BI2-512-RZ31X and BI2-S12-AZ31X.
