Description
The GRACO 564401 is a field sensitive mechanical proximity switch designed for use with MXP, MX, and MXO divider valves. It is constructed for robust industrial environments and provides reliable cycle indication in lubrication systems. The switch is explosion proof and suitable for use with oil or grease lubricants.
Key Features:
- Field Sensitive Mechanical Proximity Switch
- 564401
- Type 303 SS Housing, Buna-N or Viton O-Ring (specific to variant; see documentation for exact)
- Up to 7500 psi (see documentation for exact model variant)
- MXP, MX, and MXO Divider Valves
- Explosion Proof
- Robust stainless steel housing for durability
- Suitable for harsh industrial environments
- Explosion proof design for safety in hazardous areas
- Reliable cycle indication for lubrication systems
- Compatible with oil or grease lubricants
- Designed for use with controllers and PLCs with appropriate input impedance
Applications:
Used in industrial lubrication systems for monitoring and indicating the cycle of divider valves, particularly in environments requiring explosion proof equipment.
Installation Notes:
- Using genuine GRACO parts ensures compatibility, reliability, and safety in hazardous environments.
- Ensure the switch is compatible with the controller or PLC input impedance (typically 1500 ohms or less for illuminated models)
- For high impedance inputs, use non-illuminated models or connecting cables with LEDs for state indication
- Follow all safety and installation guidelines provided in the equipment manual
- Regularly inspect O-rings and housing for wear or damage
