Keyence EV-118M Inductive Proximity Sensor M18, Shielded

EV-118M: what this EV series sensor is and how its code reads

EV-118M is a Keyence EV series product, listed by the maker as: Main Unit, Shielded Type, M18. The EV series is a family of self-contained inductive proximity sensors in threaded metal housings, available shielded and unshielded in M8 to M30 sizes. The amplifier is inside the housing, so the sensor connects straight to a PLC input. Seven Star LLC supplies EV-118M in Oman and the GCC as an independent supplier in Muscat, not affiliated with the manufacturer.

EV is the series, 118 means M18 thread, and M denotes shielded. The unshielded sibling is EV-118U.

EV-118M offers a 5 mm distance with a 350 Hz response frequency and nickel-plated brass housing. Being shielded, it can be flush-mounted in metal brackets, which is useful on machine frames and valve brackets.

EV-118M technical specifications

Values in the table are taken from the maker’s model page for EV-118M. Treat them as nominal and confirm the exact conditions in the instruction manual before final design.

How the sensing principle behind EV-118M works

An inductive proximity sensor generates a high-frequency magnetic field at its face. When a metal object approaches, eddy currents damp the oscillation, and the electronics switch the output once the amplitude falls below a threshold. Because nothing touches the target, the sensor has no moving parts to wear.

Shielded types concentrate the field at the face so they can be flush-mounted in metal, while unshielded types project a wider field and reach farther. The detecting distance in the table assumes the standard target stated for that model, and non-ferrous metals are detected at a reduced distance.

Where EV-118M fits: related EV series parts

EV sensors replace limit switches on valve positions, door latches, cylinder ends and guard checks. Two-wire and three-wire versions exist, so confirm wiring and the PLC input type.

The EV series range includes the following part numbers, which are listed for cross-reference: EV-108M, EV-112M, EV-118M, EV-130M, EV-108U, EV-112U, EV-118U, EV-130U, EV-12M, EV-18M and EV-30M. Whether a particular combination is compatible should be confirmed from the maker’s documents. Closely related models from the same family that you may also want to compare include EV-130U, EV-108U.

Selecting EV-118M: ordering checklist

• Thread size (M8, M12, M18, M30) and shielded or unshielded.
• Detecting distance versus the real gap, with margin for target material.
• Output type, polarity and operating mode (N.O.).
• Cable length or connector.
• Temperature range and enclosure rating.
• Tightening torque and mounting nuts.

For EV-118M specifically, confirm the output type, the connection style and the rated distance shown in the table above against the real installation drawing before placing an order.

Installing and maintaining EV-118M

Tighten the lock nuts evenly, keep unshielded types clear of surrounding metal by the distance stated in the manual, and set the working gap to roughly half the rated distance for stable operation. Protect cables from mechanical damage.

Because there is no calibration, maintenance is limited to inspecting the face and cable, confirming the indicator lamp responds, and checking that mounting has not loosened from vibration.

Typical applications of EV-118M in Oman and the GCC

Inductive sensors are used throughout Oman and GCC oil and gas, power and water facilities for valve-position feedback, machine tool end stops, conveyor counting and rotating-speed detection. The metal housing tolerates dust, heat and vibration on pumps, skids and compressor packages.

Flush-mounted M18 sensors are common on valve brackets and machine frames. Extra heat, dust and humidity are normal in the region, so check the ambient temperature and enclosure rows in the table against the real mounting location, including direct sunlight on outdoor skids.
