MOUNTING DIMENSIONS
Mounting dimensions are included in this datasheet. They are
shown in English and metric equivalents. These dimensions are
for reference only. Engineering drawings may be accessed via
the Honeywell web site: sensing.honeywell.com.
Mounting holes for Types BZ, BM, BA, BE, and 6AS switches
accept pins or screws of 3,53 mm [0.139 in] diameter.
RECOMMENDED TORQUE
Mounting screws. . . . . . . . . . . . . . . . . . . . . . . . . . . 0,39 Nm [3 in-lb]*
Terminal screws. ............................ 0,45 Nm [4 in-lb]
Panel mount bushing . 0,45 Nm to 0,68 Nm [4 in-lb to 6 in-lb]
*Note: Tightening mounting screws above 0,3 Nm [3 in-lb]
changes operating characteristics and increases the possibility
of cracking the case.
UL/CSA
Honeywell basic switches are Component Recognized by
Underwriters’ Laboratories, Inc. and certified by Canadian
Standards Association. The BA, BZ, and BM line is covered
as Special Use Switches to UL Standard1054; the BE line is
covered as an Industrial Product to UL Standard 508. Agency
