Information About E3X-NH21
The E3X-NH21 is a timer-function amplifier from Omron’s E3X-NH fiber-optic sensor series, developed for use with E32 fiber units in demanding detection environments. It incorporates a red LED light source (680 nm) and supports automatic or manual fine threshold adjustment for accurate detection of small or low-contrast objects. Designed for DIN rail mounting, the unit integrates output short-circuit protection and reverse polarity protection for enhanced operational reliability. Its compact housing and selectable operation modes make it suitable for tightly spaced control panels and multi-sensor installations.
Key Features:
-
Fiber-Optic Amplifier Design: Compatible with E32 series fiber heads for flexible sensing configurations.
-
NPN Open-Collector Output: 50 mA max load current for direct PLC interfacing.
-
Timer Function Built-In: Integrated timing control for delayed output operation.
-
Selectable Light-ON/Dark-ON Mode: Configurable output logic for application flexibility.
-
Fine Sensitivity Adjustment: 13-level manual threshold adjustment for precise detection tuning.
-
Red LED Light Source (680 nm): Stable and consistent optical emission for reliable sensing.
-
Protection Circuits: Includes output short-circuit and reverse polarity protection.
-
DIN Rail Mounting: Compact housing suitable for standard control panel installation.
The E3X-NH21 delivers the reliability and precision required for high-accuracy fiber-optic sensing applications in industrial automation systems.
