Description

MAIN FEATURES

SENSING ELEMENT: hygroscopic polymer film with special treatment, guaranteeing a fast response, long lifetime and high stability

HOUSING: Fiber glass Makrolon, high humidity resistance, very high electrical insulation properties. Do not use in places with risk of condensation.

MOUNTING: front side mounting by two screws, 30 mm distance. The same mounting is also available at the backside.

SETTING: with 6.4 mm diameter shaft, 14 mm long, with 4 mm flat, located on the small lateral side

SHAFT ROTATION: Standard mechanical rotation 295°.

ADJUSTMENT RANGE: Range 20-80%: on 235 ° angular. Range 10-60%: on 224 ° angular.

CALIBRATION: at mid position at 42% RH and 22 ° C. Calibration tolerance at mid point: + / -5% relative humidity. Minimum and maximum positions have positive contact actuation

CONTACT STYLE:

  • SPDT, the NC opens when the relative humidity goes above the set-point (humidification applications), the NO contact clos- es when the relative humidity goes above the set-point (ventilation or dehumidification applications)
  • NC: NC opens when the relative humidity goes above the set-point (humidification applications)
  • NO: NO contact closes when the relative humidity goes above the set-point ( ventilation or dehumidification applications)
  • CONTACT MATERIAL:  
    • Gold plated silver: recommended when storage at high humidity conditions may occur, or when the product is used in low voltage application (electronic control boards)
    • Silver: recommended for standard resistive load application or low inductive loads

ELECTRICAL CONNECTIONS: 6.3 x 0.8 mm tabs

AMBIENT CONDITIONS :

Humidity: 5 to 95% without condensation

Ambient temperature: 5 to 40°C

RATING :

  • UL and CSA: 6A resistive, 20A LRA, FLA 7A, 240V
  • EC: 6A resistive, (3.7A inductive) 250V

OPTIONS: Change in angular position, reverse rotation, flat and shaft length and orientation change (with MOQ and/or tooling cost)
