802T Plug-In Safety Limit Switches
|
Description
The 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 allows the normally closed contacts to open when the limit switch is actuated. This opening will occur even in the event of a contact weld condition, up to 10 Newtons.
|
ATTENTION: To ensure that the normally closed (safety) contacts open, the limit switch actuator must be displaced beyond the point of Direct Opening Action (see specifications). |

Modifications
Metric Conduit Entry
To order a limit switch with a 20 mm conduit entry, add the suffix S6 to the cat. no. Example: 802T-APDS6.
Pre-wired Cable
To order a 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 1.52 m (5 ft). Extended cable lengths are available in multiples of 1.22 m (4 ft) only.
Example: To order a limit switch with a factory-installed 1.52 m (5 ft) cable, the cat. no. would become 802T-APDY5. To order a limit switch with a factory-installed 2.44 m (8 ft) cable, the cat. no. would become 802T-APDY8.
Mini-Style Quick-Disconnect
To order an 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 cat. no. Example: 802TAPDJ1.
| 5-Pin Mini-Type Receptacle (2 circuit) |
|
| 9-Pin Mini-Type Receptacle (4 circuit) |
|
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 cat. no. To order a limit switch with a DC micro quick-disconnect, add the suffix D5 to the cat. no. Example: 802TAPDR5 and 802TAPDD5.
