Key Features

PNP Open Collector Switching

The OMRON E3X-NA41 provides one PNP transistor output with a maximum load current of 50 mA. Selectable Light-ON and Dark-ON modes allow the switching behavior to be matched to a compatible PLC input or industrial control circuit.

200 µs Response Time

The standard amplifier responds within 200 microseconds for both operation and reset under specified conditions. When eight or more compatible units are mounted side by side, the specified maximum response time becomes 350 microseconds.

Manual Sensitivity Adjustment

An eight-turn endless sensitivity adjuster allows technicians to set the sensing threshold manually. The illuminated bar display and light-level margin indicators assist with sensor alignment and adjustment without requiring a numerical screen.

Red LED Fiber Optic Detection

The amplifier supplies a red LED light source for compatible OMRON fiber optic heads. Its sensing method and detection range depend on the selected fiber head, target material and installation conditions.

40 ms OFF-Delay Timer

A selectable fixed 40 ms OFF-delay timer supports applications that require the switching signal to remain active briefly after the sensing condition changes, reducing the need for a separate timing component in suitable control circuits.

Compact DIN Rail Construction

The standard amplifier has a 10 mm-wide PBT housing, pre-wired electrical connection and an IP50 rating with the protective cover attached. Multiple amplifiers can be mounted together, subject to temperature and interference-prevention limits.

Applications

  • Small-part detection in automated assembly systems
  • Fiber optic object presence sensing
  • Packaging machinery product detection
  • Electronic component positioning equipment
  • Conveyor counting and sorting systems
  • PLC-connected PNP photoelectric sensing circuits
  • Compact manufacturing equipment sensor installations
  • Maintenance of existing OMRON E3X-NA amplifier systems

Frequently Asked Questions

What is the OMRON E3X-NA41?
It is a standard E3X-NA series fiber optic sensor amplifier with a red LED light source, one PNP open collector output, adjustable sensitivity and selectable Light-ON or Dark-ON operation.


Is the E3X-NA41 a PNP or NPN amplifier?
The E3X-NA41 has a PNP output. The corresponding standard NPN model is E3X-NA11.


What power supply does the amplifier require?
The specified supply is 12 to 24 VDC ±10%, with a maximum supply ripple of 10% peak-to-peak.


What is the maximum output current?
The PNP open collector control output supports a maximum load current of 50 mA, with a maximum load supply voltage of 26.4 VDC.


What is the response time of E3X-NA41?
The standard response time is 200 µs maximum for operation and reset. When eight or more compatible amplifiers are mounted side by side, the maximum becomes 350 µs.


Does it support Light-ON and Dark-ON switching?
Yes. Both Light-ON and Dark-ON modes are selectable using the amplifier's operating controls.


Does the amplifier include a digital numerical display?
No. The E3X-NA41 uses an illuminated bar display and manual sensitivity adjuster rather than a numerical digital display.


How is the sensitivity adjusted?
Sensitivity is configured using the eight-turn endless adjustment control. The bar display and indicator LEDs help identify the received light level and switching condition.


What is the sensing distance?
There is no single fixed sensing distance for the amplifier alone. As reference examples, OMRON lists 560 mm with an E32-T11R through-beam fiber and 180 mm with an E32-D11R reflective fiber under specified test conditions.


Does E3X-NA41 include a fiber optic sensor head?
The E3X-NA41 designation identifies the amplifier unit. A suitable E32 series or other compatible fiber head must be selected separately unless explicitly included in the seller's package.


What is the difference between E3X-NA41 and E3X-NA41F?
The E3X-NA41 is the standard PNP model with a 200 µs response time, while the E3X-NA41F is a high-speed PNP variant with a faster response time designed specifically for high-speed object detection applications.
