TYPE 809 and 810

Product catalog summary
Overview: The document provides technical specifications and details for Kant Druckschalter GmbH's pressure switches, specifically Types 809 and 810. These switches are designed with normally closed (NC) and normally open (NO) contacts, respectively.
Specifications:
  • Contact Types: Type 809 (NC), Type 810 (NO)
  • Flat Connector: 6.3 mm
  • Width Across Flats: 24 mm
  • Thread Length: 9 mm
  • Adjustment Range: 0.2 – 200 mbar
  • Overpressure Safety: Up to 600 bar
  • Reproducibility: ~5%
  • Hysteresis: ~5-10%
  • Electricity Max: 2 Amp
  • Type of Protection: IP 55
  • Permissible Temperature: -20° to +100°C
  • Switching Frequency: 200/min
  • Weight: 0.09 kg
  • Voltage: 250 Volt
Materials and Applications:
  • Diaphragm Materials: NBR, FKM (VITON), EPDM (APTK), SILICONE
  • Piston Sealing: Oil, Hot water
  • 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, water, etc.
Functionality: The pressure switch operates by deforming a diaphragm or displacing a piston when pressure is applied. This movement, determined by an adjustable spring preload, actuates the switch to open or close the electrical circuit, allowing specific pressure values to be monitored.
Ordering Information: The order number is structured as ABCD, where each letter represents a specific configuration option such as type, setting range, thread, sealing element, and material.

TYPE 809 and 810-1

Pressure switch Normally closed contact (Type 809) Normally open contact (Type 810) Flat connector 6,3 Width across flats 24 Thread length 9mm ADJUSTMENT RANGE [mbar] ORDER NUMBER OVERPRESSURE SAFETY A Kant pressure switch Type 809 and 810 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. SWITCHING FREQUENCY Hydraulic oil, Machine oil, Heating oil, Nitrogen, sea water Hydraulic fluids, Petrol, Alcohol, Salt and Sulphuric acid EPDM (APTK) Hydrogen, Brake fluid, Acetylene, etc. PISTON SEALING PISTON SEALING With device connector DIN 43650 D MICROSWITCH WITH GOLD PLATED CONTACTS  Order Number Example: ABCD 809-XX-2115 The Open, Close or Change function refers to increasing pressure.
