Hammond SKH600NCC Mechanical Humidistat, 40-90% RH DIN Rail

The SKH600NCC is the mechanical humidistat in the SKH Series. It regulates enclosure heaters or fans whenever the preset level of relative humidity is reached, giving panel builders and maintenance teams a simple way to switch climate control equipment on humidity rather than temperature alone. The part is described as a Humidity Stat Celsius.

Sensing is done by a polyamide band sensor over a control range of 40 to 90% r.H., with a differential gap of approximately 5% and a switch point accuracy of +/- 4% based on 50% r.H. The contact is a change-over switch, so the same device can drive humidification or dehumidification loads.

• Humidification: 24V .. 250V AC / 2(0.2)A, min. 100 mA
• Dehumidification: 24V .. 250V AC / 5(0.2)A, min. 100 mA
• DC: 50V 1A, 75V 0.5A, min. 100 mA
• Values in brackets: inductive load at cos φ = 0.6

The ordering table lists the dimensions as 3.5 x 1.5 x 1.8 (height x width x depth), while the part's short description reads 2.41 x 1.3 x 1.4 in. The working temperature range is 30°F to 140°F (0°C to 60°C) and storage is -5°F to 180°F (-20°C to 80°C). Wiring uses a 2-pole clamp for AWG14 (2.5 mm²).

The housing color is RAL 7035 grey, protection is IP20, and the humidistat clips onto 35 mm DIN rail with the clip included. It is CE approved, RoHS and REACH compliant, and ships at 1 lb (0.45 kg).
