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 File
