Keyence EM-030 Shielded Inductive Proximity Sensor 3mm NPN IP67

Keyence EM-030 is a shielded inductive proximity sensor from the EM series, designed for non-contact detection of metal objects in tight spaces. With a compact 3 mm diameter cylindrical stainless steel housing and in-cable amplifier, it is suitable for micron‑level positioning and miniature automation equipment. Operates on 10.8 – 30 V DC, provides a 0.6 mm detection distance, and features a red LED output indicator. NPN output, 200 mA load capacity, 1.2 kHz switching frequency, and IP67 protection for use in demanding industrial environments.

Applications:

• Micro-positioning and fine alignment in semiconductor and electronics assembly

• Small parts detection in high‑speed pick‑and‑place systems

• End‑position sensing in miniature pneumatic cylinders and grippers

• Metal component presence verification in pharmaceutical and medical device manufacturing
