Honeywell 1LS1-4PG General Purpose Limit Switch

Honeywell 1LS1-4PG is a general-purpose limit switch in the MICRO SWITCH™ Compact LS series. It is a mechanical limit switch primarily used to detect the position, travel end, or presence of equipment or components.

Note: The Compact LS series offers various actuator types (such as side-mounted rotary arm, plunger, rocker arm, roller plunger, etc.). Users can select the most suitable model based on their specific mechanical triggering method (1LS1-4PG specifically refers to one actuator type; please refer to the technical specifications for specific models).

Function & Features

• The 1LS1-4PG switch contains two independent contact mechanisms, allowing simultaneous control of two independent circuits.

• The 1LS1-4PG's double-break contact design provides two break points for each circuit when disconnected, resulting in more effective arc extinguishing.

• The 1LS1-4PG is completely dustproof and can be briefly submerged in water (1 meter depth, 30 minutes).

• The 1LS1-4PG meets IP67 standards and complies with NEMA 1, 3, 4, 6, and 13 requirements.
