Omron's easy-to-use fibre amplifiers

February 2011 Sensors & Transducers

In response to customer requests for fibre-optic sensor amplifiers that are as easy as possible to use in standard applications, Omron has added the new E3X-SD models to its comprehensive E3X range of fibre amplifiers. To ensure that they are straightforward to set up and use, the new models combine simple one-button teaching with easy to read displays and an intuitive manual threshold adjustment option.

E3X-SD amplifiers are suitable for use in all photoelectric sensing applications where an amplifier that is separate from the sensing head is preferred. Examples include applications where there is insufficient space to accommodate a conventional sensor, or those that involve sensing in harsh environments, since the Omron range of fibre sensing heads includes vacuum, chemical and heat resistant types.

The new amplifiers can be set up quickly either by holding the teach button pressed while a moving target passes the sensor, or by pressing the teach button once when the target is present and again when it is absent. Alternatively the sensitivity can be adjusted manually using the up and down keys, giving users precise control over the operation of the amplifier.

In normal operation, the amplifier’s integral display shows the received light level, but as a further aid to setting this changes to the threshold value when the adjustment keys are pressed. Indicators are provided that show device status at a glance.

The high power Giga-Ray LED light sources and the advanced emission control circuitry ensure that the amplifiers offer reliable, repeatable operation and long-term operating stability. Reliability is further enhanced by an easily operated lock mechanism that clamps the fibres securely in place.

The easy-to-use E3X-SD products complete Omron’s line of fibre amplifiers and complement the recently introduced new generation of the E3X-DA-S high functionality and application specific models.
