TYPE 803 and 804

Product catalog summary
Overview: The document provides technical specifications for the Kant Druckschalter GmbH pressure switches, Types 803 and 804. These switches are designed with normally closed (NC) and normally open (NO) contacts, respectively.
Specifications:
  • Flat connector size: 6.3 mm
  • Width across flats: 24 mm
  • Height: 43 mm
  • Thread length: 9 mm
  • Reproducibility: ~5%
  • Electricity: Max. 2 Amp
  • Hysteresis: 5-10%
  • Type of protection: IP 55
  • Permissible temperature range: -20° to +100° C
  • Switching frequency: 200/min
  • Weight: 0.09 kg
  • Voltage: 250 Volt
Adjustment Range and Overpressure Safety:
  • Diaphragm: 0.2 – 1 mbar (300 bar safety), 1 – 10 mbar, 2 – 20 mbar, 10 – 100 mbar (600 bar safety), 20 – 200 mbar
  • Piston: 10 – 100 mbar (600 bar safety), 20 – 200 mbar
Materials and Applications:
  • Thread options include G 1/8, G 1/4, M 10X1, NPT 1/8, R 1/8, M 12, and NPT 1/4.
  • Sealing elements: NBR, FKM (VITON), EPDM (APTK), SILICONE
  • Body materials: Steel Gal ZN, VA 1.4305, Brass 60, VA 1.4571
  • Applications: Suitable for hydraulic oil, machine oil, heating oil, nitrogen, sea water, hydraulic fluids, petrol, alcohol, salt, sulphuric acid, hydrogen, brake fluid, acetylene, food, and water.
Functionality: The pressure switch operates by deforming a diaphragm or displacing a piston when pressure is applied. This movement, influenced by an adjustable spring preload, actuates the switch to open or close the electrical circuit, allowing specific pressure values to be monitored.
Optional Features: Device connectors 800 and 800-IP65 are available for enhanced connectivity.
Ordering Information: The order number format is ABCD, where each letter represents a specific configuration aspect such as type, setting range, thread, sealing element, and material.

TYPE 803 and 804-1

Pressure switch Normally closed contact (Type 803) Normally open contact (Type 804) Flat connector 6,3 Width across flats 24 Height 43mm Thread length 9mm Without device connector ADJUSTMENT RANGE [mbar] ORDER NUMBER OVERPRESSURE SAFETY With device connector 800 or 800-IP65 A Kant pressure switch Type 803 and 804 has an integrated N.C. / N.O. contact. When pressure is applied, a diaphragm is deformed or a piston is displaced via a lifting movement. The deformation or movement depends on an adjustable spring preload. When the switching point is reached, the diaphragm or piston has undergone a defined movement which actuates the switch and opens or closes the electrical circuit. Specific pressure values can be monitored via the switching signal. SWITCHING ELEMENT PERMISSIBLE TEMP.
