HDLS Series
Heavy-Duty Limit Switches
The HDLS Series heavy-duty limit switches are designed for a long life. Housed in
a rugged corrosion-resistant zinc body, the switch is epoxy-coated for protection.
Its unique, all-metal drive train provides consistent operating characteristics and
lasts longer than drive trains with plastic parts. The HDLS offers sintered bronze
bearings on 303 stainless steel operating shafts and all versions offer the same
actuator lever tracking dimensions for excellent design flexibility.
