A7AS

Thumbwheel Switch Easy-to-Assemble Thumbwheel Switch Dustproof construction ensures highly reliable performance at low voltage and very small current even under adverse environmental conditions s Switch units can be assembled simply by fitting the integral hook coupler of each unit into the mating unit, thus eliminating the need of bolts and nuts for assembly s A7AS Ordering Information s SWITCH UNITS Part Number Front mounting solder terminals Light gray case Black case A7AS-203 A7AS-203-1 A7AS-206 A7AS-206-1 A7AS-206-PM A7AS-206-PM-1 A7AS-207 A7AS-207-1 A7AS-219 A7AS-219-1 A7AS-222 A7AS-222-1 Output Code 03 (decimal code) 06 (binary code) (binary code w/+, – display) 07 (binary code w/diode provision) 19 (decimal code w/diode provision) 22 (compliment of BCD) s ACCESSORIES Part Number For front mounting type switch assembly terminals Light gray Black A7AS-M A7AS-M-1 NRT-Ps NRT-Ps -1 NRT-C NRT-C NRT-CP NRT-CP Accessory End Cap Spacer Connector Solder terminal PC terminal Note: 1. When placing your order, please specify the model numbers and quantities of required switch units, end caps, and spacers, respectively. (Note that switch units and accessories are not factory-assembled for shipment.) 2. Switch case, end cap, and spacer are made of polyacetal resin. 3. One of the following alphabetic codes must be filled into the boxed part of the model number to specify a legend to be hot stamped on the required spacer. 4. End caps come as a set -- left and right.
