Overview
The Honeywell LSH1A is a MICRO SWITCH heavy-duty limit switch from the HDLS series, engineered for industrial automation and machinery control. The modular construction allows for a wide variety of actuator styles, operating heads, and electrical circuitry options. The plug-in versions greatly reduce downtime on production lines with high actuation rates as replacement of the switch is accomplished in seconds. The LSH1A features a side rotary actuator and is rated for 10A at 600Vac.
Key Features
- SPDT contact configuration (1NO/1NC) for versatile switching logic
- Plug-in base receptacle contains all wiring and conduit connection while the switching component easily assembles with two screws.
- Side rotary actuator head for rotational motion detection
- Ideal for demanding indoor and/or outdoor environments subjected to shock or vibration, temperature extremes, dust, splashing water, coolant, and/or hose-directed water.
- Robust construction for long service life in harsh industrial settings
