Description
Bulletin 802T Direct Opening Action limit switches have been
designed for use in control reliable applications and safety
applications per ISO 14119. These limit switches utilize the same
mounting dimensions as other NEMA style limit switches. The
rugged metal construction and plug-in body are designed for use in
harsh industrial environments.
Direct Opening Action assures that the normally closed contacts
open when the limit switch is actuated. This opening will occur even
in the event of a contact weld condition, up to 10 Newtons.

Modifications
Metric Conduit Entry
To order a limit switch with a 20mm conduit entry, add the suffix
“S6”
to the catalogue number.
Example: 802T-APDS6
Pre-wired Cable
To order factory installed pre-wired type STOOW-A cable (5
conductor), add the suffix
“Y”
plus the number of feet required.
The standard cable length is 1.52m (5ft). Extended cable lengths are
available in multiples of 1.22m (4ft) only.
Example:
To order a limit switch with a factory installed 1.52m (5ft)
cable, the catalogue number would become
802T-APDY5.
To order
a limit switch with a factory installed 2.44m (8ft) cable, the catalogue
number would become
802T-APDY8.
Mini Style Quick-Disconnect
To order a Bulletin 802T pre-wired limit switch with a 5-pin (2
circuit) or 9-pin (4 circuit) mini connector, add the suffix
“J1”
or
“J9”
depending on desired wiring (“J9” wiring not available for 4
circuit models) to the catalogue number.
Example: 802T-APDJ1
5-Pin Mini-Type Receptacle (2 circuit)
“J1” Wiring
“J9” Wiring
Micro Style Quick-Disconnect
Micro quick-disconnects are available with a 5 pin 2 keyway AC or 5
pin single keyway DC. To order a limit switch with a AC micro
quick-disconnect, add the suffix
“R5”
to the catalogue number. To
order a limit switch with a DC micro quick-disconnect, add the
suffix
“D5”
to the catalogue number.
Example: 802T-APDR5
and
802T-APDD5.
