Basic Knowledge of Photoelectric Sensors
Standards and Regulations of Photoelectric Sensors
Degree of Protection (IP: International Protection)
The protective structure is stated with the degree of protection defined by IEC, International Electrotechnical Commission, Japan Industrial Standards and Japan Electrical Manufacturers' Association Standards.
This can be referred to know environmental protection of sensors.
Solid Particle Protection
| Rating | Description | |
|---|---|---|
| IP5□ |  |
Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment. |
| IP6□ |  |
No ingress of dust; complete protection against contact. |
Liquid Ingress Protection
| Rating | Description | |
|---|---|---|
| IP□5 |  |
Water projected by a nozzle against enclosure from any direction shall have no harmful effects. |
| IP□6 |  |
Water projected in powerful jets against the enclosure from any direction shall have no harmful effects. |
| IP□7 |  |
Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time. |
| IP□8 |  |
The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. |
IP69K
IP69K rating is defined in DIN 40050-9 of Germany extended the IEC 60529 rating system for high-pressure, high-temperature wash-down applications.
Enclosures must not only be dust-tight, IP6X, but are also able to withstand high-pressure and steam cleaning.
Testing Conditions
Water is sprayed with the following conditions to a test device sits on a turntable that rotates at 5rpm.
Water pressure:80~100bar
Flow rate:14~16L/m
Water temperature:+80℃ / -5℃
Distance from nozzle:100~150mm
Spray angle:0°, 30°, 60°, 90°
Spray time:30s each angle
* The IP69K rating does not guarantee operation of a rated product under all of the above conditions.
Water or oil on the optical surface could cause light refraction to interfere correct detection.
Testing Method
Noise levels are defined at distances from a device and spark generated by metal filing.

Shock Resistance Test (Reference data for the KR-Q series)
Passed for drop testing from 1.4m height!!
(The sensor is not damaged, even when it is hit with a sharp edge.)
Test Methods
A weight of 1kg is dropped to a product from the top.
The weight is guided through a pipe to apply the shock evenly on a side of sensor.
The height to drop the weight is raised by 10mm, and at each height, operations of the sensor are tested.
