It has a switch actuation force of 0.55N and a contact electrical life of 500,000 cycles. It is UL, cUL, and TUV approved, and is also CE certified.
Application Fields
The TFCDH8SP0040C is typically used in the following applications:
- Automatic Doors and Gates
- CNC Machine Control
- HVAC Systems
- Robotics
- Security Systems
- Sensors
Working Principle
The switch operates by detecting a physical position or profile and then activating or deactivating a circuit. A lever arm and an actuation point form the switch\'s operating mechanism. When an object comes into contact with the actuation point, the lever arm is turned, which actuates the contacts.
The choice of the actuation point depends on the desired application and the range of movement available. When the actuation point is reached, the switch is activated and the contacts are opened or closed, depending on the desired effect.
The actuation force of the TFCDH8SP0040C (0.55N) ensures reliable switching operation, even when the lever arm is subjected to repetitive motion. The switch is a reliable and economical solution for a wide variety of applications.
