Limit and Enclosed Switches
CLS Series
Momentary Cable Pull Limit Switches: For Signaling Applications
FEATURES
ɀ Offered in Single Head and Duplex
Head versions
ɀ Optional direct acting contacts enhance
reliability
ɀ Duplex Head switches cover up to 400
ft. cable spans (200 ft. in each direction)
ɀ Single Head switches have one normally
open auxiliary contact, while Duplex
Head switches have up to three
normally open and two normally closed
auxiliary contacts
ɀ Four conduit opening thread size
options: 1/2-14 NPT, 20mm, PF1/2 and
PG13.5
ɀ Compact size of Single Head switches
fits into tight spaces
MOMENTARY (CONTACT SWITCH) OPERATING HEAD
ɀ Sealed to NEMA 1, 3, 4 and 13
ɀ Smart Distributed System output
available on Duplex version for
monitoring only
Momentary CLS Series Cable Pull Limit Switches are designed for signaling applications;
they are not to be used as emergency stop devices. (For emergency stop applications, see
the Maintained Cable Pull Limit Switches in the Safety Products catalog.)
ɀ UL listed
Whenusingdirectactingcontacts,MomentaryCablePullLimitSwitchesprovideameansto
manually force disconnection of a normally closed control circuit by pulling on an attached
cable. Momentary switches cause contact transfer if the cable is manually pulled and held.
When the cable is released, switch contacts return to their original state. Momentary
switches have either direct-acting contacts or snap-action contacts.
ɀ CSA certified
ɀ CE certified
ɀ Temperature range: –1° to 70°C (30° to
158°F)
ɀ Available with indicators
ɀ Duplex versions available with high
visibility pilot light
Cable length may be up to 200 ft. in a straight line for Single Head switches, and up to 400 ft.
(200 ft. in each direction) for Duplex Head switches.
