Photomicro Sensors

These Optical Sensors provide a compact, low-cost method to detect workpieces. Many models are available, including Slot-type Sensors (through-beam) for non-modulated or modulated light, Reflective Sensors, and Sensors with separate emitters and receivers.

Features of Photomicrosensors

Photomicrosensors have the following advantages over ordinary photoelectric sensors with built-in amplifiers

(1) Many Different Shapes in One Model Series

The EE-SX67 Series, for example, has models with eight different slot configurations, allowing the customer to choose the best configuration for the installation position.

(2) Low Price

Ratings and performances are limited to those required for building into equipment, and the required IP degree of protection is easier to achieve, making prices very reasonable.

(3) Downsizing Is Possible with the Sensing Distances Required for Building into Equipment

The standard sensing distances (slot width) are specifically intended to be used for building into equipment. Slot-type Sensors, for example, have a 3.6 mm or 5 mm sensing distance. Diffusereflective and Limited Reflective Sensors have a sensing distance of less than 5 mm, and etroreflective and Through-beam Sensors, less than 1 m.

(4) Indicator Lighting Mode

The indicator on many Photomicrosensors lights when light is incident. Some Photomicrosensors have specific models on which the indicator lights when light is interrupted. When lighting the indicator for position adjustment applications of Slot-type Sensors, for example, it may be more convenient to use a model that lights the indicator when light is interrupted. When using the indicator to check the power supply status, on the other hand, it may be convenient to use a model that lights the indicator when light is incident.

(5) Other Specifications: Degree of Protection and Output Current

A waterproof structure is not required because it is assumed the Photomicrosensors will be built into other equipment, and the output current rating can be kept low. Also, most models can operate on a 5-VDC power supply.
