HT800 30.5 mm pilot devices The logical choice for value, durability and reliability The heavy-duty HT800 Series is a family of 30.5 mm pushbutton devices that includes momentary, illuminated and mushroomhead pushbuttons, selector switches, indicating lights and push-pull units. The HT800 devices have a familiar appearance found in most industrial applications and are suitable for replacement of several other manufacturers' 30.5 mm devices. Features Unlike their closest competitor, the HT800 devices are all ULT (NEMAT) Type 4X rated for resistance to corrosion. In addition, all HT800 devices are shipped complete with grounding hardware to ensure compliance with electrical installation requirements. With most competitive devices, grounding kits have to be purchased separately. Rugged metal construction, handsome appearance, extra features and competitive prices make the HT800 Series the logical choice for OEMs and panel builders looking for value, durability and reliability. * Die-cast metal housings create robust and heavy-duty devices that can endure repetitive and heavy-handed use in industrial environments * Anodized aluminum mounting rings are corrosion-resistant and are UL (NEMA) Type 4X rated * Double-V gaskets and O-rings seal operators against contaminants to maintain dust-tight, watertight and oil-tight panel ratings (UL Type 4, 12 and 13 rated) * Pilot-duty UL Type A600 rated contact blocks handle inductive loads up to 0.35 power factor (PF) compared to general-purpose ratings that have only a 0.75 PF rating * Contact blocks have clear transparent housings to allow easy visual inspection of contacts * Contact blocks are color coded (white for NO and black for NC) to permit easy identification and troubleshooting * Movable contacts in contact blocks have a "reliability" ridge to ensure solid electrical contact under a variety of electrical conditions * Logic level contact blocks have gold-plated contacts to ensure circuit integrity down to 1 mA @ 5V * Extended height bulbs provide side illumination of illuminated pushbuttons and indicating lights * Contact blocks mount sideby-side and are stackable; they can be mounted in left and right positions or rotated to mount in upper and lower positions. This flexibility permits correct positioning and alignment of the terminals to line up with existing wires in retrofit applications * Bright and long-lasting LEDs are available in six colors * Selector switches can be converted from 2-position to 3-position and vice versa by rotating the internal cams-- a nice option to have on the job site * Knob and lever assemblies can be rotated every 22.5 degrees to suit various panel layouts Product range Technical specifications and data Momentary pushbuttons Mechanical Ratings * * Flush, extended and 40 mm diameter mushroomhead type Black, red or green Illuminated pushbuttons * With or without protective guards * Incandescent or LED * Full voltage or transformer type * 24V or 120V * Red, green, amber, clear, white, yellow and blue Indicating lights Description Frequency of Operation Pushbuttons Selector switches Push-pull operators Mechanical Endurance/Life Pushbuttons Selector switches Push-pull operators Climatic Conditions Operating temperature Storage temperature Altitude Humidity Terminals Contact blocks Light units Specification 6000 operations per hour 3000 operations per hour 3000 operations per hour 10 x 106 operations 6K Ops/Hr six--NO on left and six--NC on right 250 x 10 three operations 3K Ops/Hr two--NO on left and two--NC on right 250 x 10 three operations 3K Ops/Hr six--NO on left and six--NC on right 10 to 140F (-12 to 60C) -40 to 176F (-40 to 80C) 6562 ft.
