Overview
The Honeywell 2LN1-3-RH is an enclosed snap action limit switch from the Micro Switch LN series, engineered for demanding industrial environments. The LN switches are designed to withstand rapid hammer-blow actuation, with the precision switch unit inside protected from impact on the actuating plunger. The RH suffix designates a right-hand actuator position as viewed from the nameplate.
Key Features
- 10A snap action SPDT (Single Pole Double Throw) contact configuration
- Individual seals around each lead wire and cover plate protect the switch cavity from condensate, oil, and dust
- Adjustable roller arm actuator with 13.3N linear actuating force and screw mount design
- 3-foot lead wire length for flexible installation
- Double break contact mechanism for reliable load breaking
- No. 14 wire leads with conduit hub seal
