ICTS-New Sensors Replacement ReliabilityTest

We managed to get two samples from Keyence and Omron for testing of reliability. Both works on same principal but come with 20% pricing different.

PZ-V31 Keyence Self Contained Photosensor Switch Reflective 300m/LCD


Automatic Calibration Photoelectric Sensors
• Detections are unaffected by variations in target color or angle
• Excellent resistance to dust and dirt
• One touch, fully automatic calibration
• Unaffected by highly reflective target backgrounds
• 40 model variations available including quick disconnect types
• High-power red LED(Except for PZ-M71/V71)
Automatic calibration type. Virtually eliminates all detection and stability problems inherent with conventional photoelectric sensors.


Visible Red Beam (All models)
Allows for easy positioning of the beam spot on the target and quick alignment of the sensor heads.
M3 Stainless Steel Internal Thread
Improved Mounting Strength
• The PZ-V/M has an M3 thread.• This ensures the PZ-V/M is securely mounted bydoubling the mounting strength
High-power Custom E-max LED
Suitable for Dusty Environments
• A high-powered LED allows the PZ-V/M to function normally in very dustyenvironments.
IP-67 Rated Waterproof Housing
All Models IP-67 Rated
• IP-67 means the PZ-V/M can be used in even the harshest environments.• The sensor will also operate environments subject to water and other liquids.
HighIntensity Pass/Fail Indicator
Improved Visibility
• The sensor has a largevisual display and high-intensity LED. • Pass/Fail conditions can be easily seen allowing for remote monitoring of sensor operation.



E3S-CL Omron Background Suppression Sensor

Photoelectric Sensor With Adjustable Setting Distance in Rugged Metal Housing
Background suppression sensor with stable detection regardless of color, material, or size of a detecting object.
Adjustable setting distance: 2% or less differential travel at 20 cm.
Sensing unaffected by dirty lens.
Compact and with a long detection distance of 50 cm (E3S-CL2).
Solid body provides excellent durability.
Eliminates background influences with a hysteresis of only 2% max. (E3S-CL1).NPN/PNP output is switch selectable for easy application anywhere.
Light on/Dark on selectable.
Easy distance adjustments with a six-turn adjustment with indicator.
Mutual interference prevention function.


Test Method
1- Day and night time
2- Stationary and moving conveyor
3- Stationary and moving mooncakes
4- Actual production


Observation
1- The frequency of malfunction (missing signal or unnecessary signal triggered)
2- Sensor recalibration time for different product input
