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 Core Specifications: Sensing distance: 0.6 mm ±15 % Standard target (iron, t = 1 mm): 5 × 5 mm Hysteresis: 10 % max. of sensing distance Response frequency: 1.2 kHz Operation mode: N.O. (normally open) Indicator: Red LED Technical Specifications: Output: NPN open‑collector, 200 mA (40 V) max., residual voltage 1 V max. Supply voltage: 10.8 – 30 V DC, ripple (P‑P) 10 % or less Current consumption: 12 mA or less Housing material: Stainless steel Cable length: 2 m Protection rating: IP67 (IEC60529) Ambient temperature: –25 … +80 °C (no freezing) Relative humidity: 35 … 95 % RH (no condensation) Weight: approx. 36 g (including nuts and 2 m cable) Advanced Specifications: Type: Shielded (flush mount) Temperature characteristics: ±10 % max. of sensing distance at +23 °C, within –10 … +70 °C Tightening torque: 1.5 N·m max. Compatibility information: Belongs to the Keyence EM series of inductive proximity sensors with in‑cable amplifiers. Designed for use with Keyence EM‑series amplifiers — the amplifier is built into the cable (no separate amplifier unit required). For applications requiring PNP output, use EM‑030AP.
