Limit Switches 3SE03 North American Limit Switches General Information Features Modular plug-in Features • UL Listed, CSA Certified. • UL File: E47512 • All Metal Captive Screws. • Keyed, Four-Directional Head. • Steel-Reinforced Diaphragm Seal Between Operational Head And Switch Body. • Permanent Instructions for Adjusting Operational Head. • Modular, Plug-In Housing 1.Heavy-Duty, Bifurcated, Plug-In Prongs. 2.Ample Receptacle Wiring Space with 1/2 - NPT threaded conduit opening. 3.Stepped Terminals On Single Pole; Deep Center Trough On Double Pole. • NEMA Type 6P Submersible 1.Completely Sealed With Epoxy. 2.SOOW-A Cable or Prewired Receptacle With Pin Connector. 3.Factory wired cable features a 350 pound pullput capacity. • Rotary heads are field convertible CW, CCW, or both without special tools. Prewired receptacle with pin connector Design Modular Plug-In Housing These heavy duty plug-in limit switches may be provided as complete devices using a composite catalog number; or, separately as components; operating head, plug-in module and base receptacle. Example: Complete Switch: 3SE03-AR1 Single Pole, Double Throw contacts with Side Rotary, Momentary Head Components 3SE03-SA Single Pole, Double Throw Plug-in Module 3SE03-DR1 Side Rotary Head, Momentary 3SE03-RA Standard, Single Pole Receptacle, 1 NO + 1 NC Since components may be interchanged, operating heads, plug-in modules and receptacles may be combined to satisfy most of your everyday limit switch requirements. This leads to less inventory with greater flexibility. Operating heads include side rotary; plain and roller plunger; and, wobble. A variety of levers are available. The zinc die-cast housing has an epoxy finish to protect against corrosion. All screws on the module and head are captive. Prewired cable NEMA Type 6P Submersible These heavy duty prewired, factory sealed switches meet the demanding enclosure requirements of UL (NEMA) Type 3, 4, 4X, 6P, 12, and 13. They are intended for wet environments where the integrity of the threaded conduit and switch body seals must be assured. The switch body cavity including threaded conduit entry is completely sealed with epoxy. An 8 foot, 5 or 9 conductor SOOW-A cable; or 5 or 9 pin prewired receptacle with pin connector is provided as standard. Switches are provided as complete devices using composite catalog numbers; or, separately as components; operating head and switch body. UL (NEMA) Type 6P switches are designed to provide a degree of protection against the entry of water during prolonged submersion at limited depths (tested with a 6 foot head of water for 24 hours). Both the Modular Plug-in and the (NEMA) Type 6P Submersible styles provide 60 Amp make and 6 Amp break—120V AC and 10 Amp continuous current for 120, 240, 480 and 600V AC. The circuit contact configuration depends on the device selected and the application criteria. Switches are available with momentary or maintained operating heads; and, single pole, double pole or center neutral (modular, plug-in only) contact configurations. 3SE03 limit switches offer a new standard of reliability and quality in automatic control circuits under heavy duty applications. Plug-in module and receptacle are keyed. 13/62 Siemens Industry, Inc.

Siemens Industry, Inc. Industrial Controls Catalog Product Category: LIMT 13/75 Mechanical Safety 3SE7 Cable-Operated Switches General Information Application Cable-operated switches are used for monitoring or for EMERGENCY-STOP facilities on particularly endangered system sections. They are available with metal enclosures. Principle of operation The switch contacts of the cableoperated switches and the conveyor belt unbalance protection devices are positive opening. 3SE7 1.0 / 3SE7 310 Molded plastic / metal enclosure As the effective range of a cableoperated switch is limited by the length of the pull-wire, large systems can also be protected. Cable-operated switches (requiring pulling at both ends) and conveyor belt unbalance trackers are used primarily for monitoring very long belt systems. Specifications Switches with latching for implementation in EMERGENCYSTOP equipment correspond to the EN 418 standard. Cable-operated switches with one-side operation are held in free position by the pre-tension force on the turnbuckle. • In the 3SE7 140, -150 and -160 cable-operated switches, both switching contacts are available for cable-break/cable pull signaling. The NO contact is used, for example, for signaling purposes. For switches with latching, with a pretensioned cable, the locking must be deactivated beforehand in order to return the switch to its free position.
