Keyence EM-038-Z High-frequency oscillation proximity sensor

Keyence EM-038-Z proximity sensor belongs to the Keyence EM-038 series of proximity sensors. It may differ from the standard EM-038 in some features or configurations. Here is an introduction to it:

General features

Detection principle: Based on the principle of high-frequency oscillation, when a metal object approaches the detection surface of the sensor, it will cause the amplitude of the oscillation circuit to change, thereby detecting the proximity of the object.

Structural design: Continuing the design of the EM-038 series, it usually has a small and compact appearance, adopts a 3.8mm cylindrical design, and is suitable for installation in a small space.

Performance parameters

Detection distance: Close to the standard EM-038, the detection distance is 0.8mm±15%, which can effectively detect metal objects at close range.

Detectable objects: Mainly used to detect ferrous metals, with good detection sensitivity for objects made of iron, steel and other materials.

Response frequency: Reaching 1.2kHz, it can quickly respond to the approach and departure of metal objects, and is suitable for the detection of high-speed moving objects.

Power supply voltage: The working power supply voltage range is generally 10.8 to 30VDC, with a wide voltage adaptability range, and can work stably under different power supply conditions.

Output type: Usually NPN output, convenient for connection with various industrial control systems, the output signal can directly drive relays, PLCs and other equipment.
