TYPE 807 and 808

TYPE 807 and 808

Product catalog summary
Overview: The document provides technical specifications for the Kant Druckschalter GmbH pressure switches, Types 807 and 808. These switches are designed with normally closed (NC) and normally open (NO) contacts, respectively.
Specifications:
  • Dimensions: Width across flats is 24mm, height is 82mm, and thread length is 9mm.
  • Adjustment Range: Varies from 0.2 to 200 mbar, with overpressure safety up to 600 bar.
  • Reproducibility: Approximately 5%.
  • Hysteresis: 5-10%.
  • 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, SILICONE.
  • Applications: Suitable for hydraulic oil, machine oil, heating oil, nitrogen, sea water, hydraulic fluids, petrol, alcohol, salt and sulphuric acid, hydrogen, brake fluid, acetylene, food, and water.
Connection Types: Various thread types including G 1/8, G 1/4, M 10X1, NPT 1/8, R 1/8, M 12, and NPT 1/4.
Body Material Options: Steel Gal ZN, VA 1.4305, Brass 60, VA 1.4571.
Functionality: The pressure switch operates by deforming a diaphragm or displacing a piston when pressure is applied. This movement, dependent on 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 807 and 808-1

TYPE 807 und 808 Pressure switch Normally closed contact (Type 807) Normally open contact (Type 808) Width across flats 24 Height 82mm Thread length 9mm ADJUSTMENT RANGE [mbar] ORDER NUMBER OVERPRESSURE SAFETY A Kant pressure switch Type 807 and 808 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.
