Omron E2E-X4C312 2M Inductive Proximity Sensor

The Omron E2E-X4C312 Inductive Proximity Sensor is designed for non-contact detection of metallic targets in industrial automation systems. As part of the E2E NEXT sensor family, this model combines a compact M12 cylindrical housing with a 4 mm sensing distance and dual-output functionality. The sensor is intended for applications where reliable object detection is required under demanding environmental conditions.

The Omron E2E-X4C312 Inductive Proximity Sensor utilizes a shielded sensing structure, allowing installation in machinery where surrounding metal components are present. Its nickel-plated brass housing and high ingress protection ratings support deployment in production environments exposed to oil, coolant, moisture, and washdown procedures.

Technical Description

This sensor features an M12 threaded cylindrical body with a quasi-flush mounting configuration. It provides a sensing distance of 4 mm and incorporates both normally open and normally closed switching outputs in a single device. The NPN transistor output architecture enables integration with a wide range of PLCs, controllers, and automation platforms.

The sensor is supplied with a 2-meter oil-resistant PVC cable, simplifying installation in machinery where connector-based wiring is not preferred. The compact body length makes it suitable for installations where available mounting space is limited.

Working Principle

The sensor operates using an electromagnetic field generated at the sensing face. When a metallic object enters the detection zone, eddy currents are induced in the target material. These currents influence the oscillator circuit inside the sensor.

The internal electronics continuously monitor changes in oscillation amplitude. Once the predefined detection threshold is reached, the switching output changes state and transmits a signal to the connected control system.

Because no physical contact occurs during operation, wear on mechanical components is minimized. This approach supports long-term detection reliability in repetitive motion applications.
