Product Introduction

Product Positioning

3SE5000-0AA03 is an operating head accessory for SIRIUS 3SE5 position switch. It does not contain switch contacts and must be used in combination with the 3SE51 basic switch body. It is suitable for applications where roller contact triggering is used, such as machine travel end point, door position, and conveyor line positioning. It can also be used as a maintenance replacement part for existing limit switch operating heads.

Core Product Advantages and Features

Metal swing lever

The lever is made of metal and is 27mm long. The trigger angle can be adjusted according to the position of the cam or stop, making it suitable for long-term use in industrial machines.

19mm ball bearing roller

The roller has a diameter of 19mm and adopts a ball bearing design, which ensures smooth rotation when in contact with the stop, reduces wear, and improves triggering stability.

Forced open circuit feature

It has a positive opening function and can be used with the corresponding switch body for safety-related circuits that require ensuring that normally closed contacts are indeed opened.

Mechanical life 15 million cycles

Typical mechanical life is 15,000,000 operations, operating temperature is -25 to +85°C, and it can be fixed with screws in any direction.
