DJ Series 2 SPDT Hydraulic Pressure Switch

Brand: Orion Instruments

DJ series pressure switches are housed in pressure die cast Aluminum powder coated enclosure and are recommended for panel mounting or outdoor service based on the type of enclosure opted for. 

No stage differential can be set in these 2 SPDT versions (DJ series). 

Both microswitches are synchronized for operation within practical limits and a slight stage difference is bound to remain between the setpoints (generally not exceeding 2% of FSR). 

The repeat accuracy is better than ±2% Full Scale. 

Two separate connectors to DIN 43650 are provided for electrical wiring for two independent circuits. 

Pressure port is 1/4" BSPF standard.
Features
  • Compact Separate chamber for working parts

  • Electrical rating: 5 A, 250 Vac; 0.2 A, 250 Vdc (res.) 
  • Electrical element: SPDT snap action microswitch 
  • Pressure port: 1/4" BSPF
