Overview
Honeywell LSA1A1 is a precision snap-action heavy-duty limit switch from the MICRO SWITCH HDLS (Heavy-Duty Limit Switch) series. The LSA1A is the original heavy duty limit switch by Honeywell Micro Switch, engineered for detection of presence or absence in areas where physical contact is allowed. The modular construction allows for a wide variety of actuator styles, operating heads, and electrical circuitry options.
Key Features
- Plug-in design greatly reduces downtime on production lines with high actuation rates as replacement is accomplished in seconds
- Uses all metal gears for a longer MTBF (mean time between failure) as opposed to those made with plastic gears
- NEMA 1, 3, 4, 4X, 6, 6P, 12, 13 and IP65/66/67 environmental sealing
- Housed in zinc die cast construction for corrosion resistance
- UL and CSA rated
- Side rotary actuator configuration for flexible mounting
Technical Specifications
- SPDT (Single Pole Double Throw) configuration
- Maximum current rating of 10 A @ 24VDC
- Operating temperature range: -12 °C to 121 °C
- Conduit termination style
- Dimensions: 41.1 mm length × 106.7 mm height × 62 mm depth
- Voltage rating: 600VAC maximum
Typical Applications
Honeywell Micro Switch limit switches are tested tough for industrial machinery and also includes units which will withstand shock, vibration, washdowns and outdoor environments. Common uses include machine tool position sensing, production line equipment detection, conveyor systems, and heavy industrial automation requiring reliable snap-action switching in challenging environments.
