QUALIFICATION: Single submission: Restricted to switch submitted. Group submission: See table V. QUALIFIC
12、ATION: Single submission: Restricted to switch submitted. Group submission: See table V. Part or Identifying Number (PIN): Consists of “M“ prefix followed by spec sheet number; a dash (-); and a five-letter code. The five-letter code identifies the configuration, electrical rating, and pressure sett
13、ing mode (code from table I); high-pressure setting (coarse value code from table II) followed by fine value with applicable tolerance (code from table III); and low-pressure setting (coarse value code from table II) followed by fine value with applicable tolerance (code from table III). The five-le
14、tter code used in the following example identifies a switch of configuration 1, low level to 1 ampere resistive at 28 V dc, which actuates on increasing pressure at 1.5 0.5 lbf/in2and deactuates on decreasing pressure at .5 0.5 lbf/in2. EXAMPLE: M9395/39- A A J “M“ prefix and specification sheet num
15、ber A G Configuration, electrical, rating, and pressure setting mode = code “A“ of table I High-pressure setting = code “A“ of table II (coarse value of 0 lbf/in2and code “J“ of table III (fine value of 1.5 0.5 lbf/in2). LOW-PRESSURE SETTING = Code “A“ of table II (coarse value of 0 lbf/in2and code
16、“G“ of table II (fine value of 0.5 0.5 lbf/in2). NOTE: Design limitations (actuation values and tolerances, deadband and actuation values and tolerances) should be coordinated with the manufacturer(s) listed on the QPL for this spec sheet before specifying a particular “M“ number. The fact that oper
17、ating characteristics can be coded does not necessarily mean that it can be manufactured or acquired.
