Safety Interlock Switches

Rope Pull Emergency Stop Switch

  • Rope spans up to 200 m (656 ft.) makes this switch ideal for applications where long rope spans are required
  • Heavy-duty housing—the die-cast housing and stainless steel eye nut make the XER1032 suitable for demanding industrial applications
  • IP67 (NEMA 6) enclosure enables the XER1032 switch to with- stand water washdown cleaning
  • Integral E-stop—the optional E-stop button provides emergency stopping capability at the extreme end of the installation and is eld serviceable
  • Tension indicator makes system setup and rop tension mainte- nance easy
  • Contact arrangement of 1 N/C + 1 N/O
  • Vibration tolerant—the snap-acting switch contacts protect against nuisance tripping due to vibration
  • Long life—the XER1032 switch is designed for a minimum of one million actuations
  • Reset button—the blue reset button must be pushed in order to return to “machine run” condition following switch actuation by a pulled or slacked rope
  • Rubber bellows contain UV inhibitor making the switches suitable for outdoor applications



Specifications are subject to change without notice.

Note: The safety contacts of the Omron STI switches are described as normally closed (N/C)—i.e., with the rope properly tensioned and the machine able to be started.

Explosion-Proof Classification:

The explosion-proof models of safety interlock switches are specifically designed for potentially explosive atmospheres while retaining the features and operating characteristics of the conventional models.

A sealed flameproof contact block makes the explosion-proof interlock switches suitable for use in European Zone 1 and Zone 2 environments, which are typical of those found in the chemical and petrochemical industries.
All switches are classified by the European method as EEx d
II C T6. For a full explanation of the classification method, see “Hazardous Location Rating Systems for Interlock Switches” in The Safety Library Section of this catalog.

These switches are not suitable for use in atmospheres containing group i gases, e.g., methane ( redamp). These switches DO nOt meet all conditions of the US classification of class i, Div 1, due to the differences between european and US classification methods. in the US and Canada, these products can be used in areas classified as class i, Division 2 in groups A (acetylene), B (hydrogen), c (ethylene) and D (propane).
