Industrial SND4172-SL2-A Limit Switch

The Suns Industrial SND4172-SL2-A Limit Switch is a slow-action, single-conduit-entry switch from Suns’ SND4 Safety Limit Switch family, built for rugged machine control and safety interlock tasks. The SL2 designation identifies a slow-actuation variant designed for dependable position sensing at device endpoints, with a standard footprint that integrates with Suns' modular SND4 lineup. This model carries an electrical rating of up to 10 A at 600 V AC (EN60947-5-1), making it suitable for control circuits in conveyors, presses, and packaging machinery. The base SND4172 platform is noted for the single conduit entry configuration, simplifying field installation and enclosure routing. The SL2 option designates a slow-action contact arrangement within the SND4 family; exact contact configuration (NO/NC) varies by submodel, so the specific variant should be verified for your application. Common applications include end-of-travel detection for gates and stops, machine guarding interlocks, and general limit-switch duties in industrial automation where robust operation and long service life are required. As part of the SUNS portfolio, this switch is designed for reliability in demanding environments and can be paired with other SND4 devices for extended control schemes.
