Why Keyence Sensors Lead the Market
The PZ-G51EP shows this quality. It is a sensor you can trust. It resists oil. It resists water. The housing is strong. It protects the electronics inside. When you choose Keyence, you choose peace of mind.
Easy Setup in Any Industrial Condition
It has a bright beam. You can see it clearly. This makes alignment fast. You line it up, and you are done.
It fits in tight spots. The condition of your factory does not matter. It mounts with an M18 nut. This is a standard size. Or you can use the quick brackets.
High Power for Tough Control Tasks
Weak sensors fail when the target is far. The PZ-G51EP has mega power. It can detect objects up to 20 meters away. This is twice as far as many old models.
This power helps up close, too. It burns through dust. It works even if the lens gets a little dirty. This ensures stable control.
Simple Wiring with M12 and PNP
The PZ-G51EP uses an M12 pigtail. This is a quick connector. You snap it together. It is secure. It resists vibration.
The output is PNP. This is standard for modern PLCs. It integrates easily. You do not need special cards. The cable is short (300mm) with a connector. This keeps your machine clean. No long coils of wire to hide. It is neat and professional.
