Cable Glands For Full EMI Protection



Winning the war against electromagnetic interference (EMI) on today’s factory floors requires attention to detail. One of those details involves the ability of cable glands to contribute to a reliable grounding system.
Left unprotected, cable glands transmit electrical noise that can wreak havoc on motor-driven industrial processes. Many types of cable glands feature shielding to keep EMI at bay, yet the effectiveness of that shielding  can vary widely from product to product.
The ease of installation can vary as well. Some shielding options have difficult termination methods or grounding connections that can drive up labor cost and time.  
With SKINTOP® MS-M Brush, our engineers have addressed both the shielding and installation issues. As its name suggests, this cable gland features a brush-type grounding connection that:
  Enhances EMI control. Unlike other connection methods, such as the grounding clamps commonly used on drive systems, the brush provides continuous 360° contact around the cable’s screen braid. This continuous contact protects against EMI by lowering the resistance of current ground path and providing a low impedance connection between the cable shield and the housing.
  Eases Installation. Making an EMI-free connection between cable and the SKINTOP cable gland is simple. Installers simply insert the cable, push the screen braid into the brush and tighten the cable gland assembly. Other grounding methods require far more effort to make the termination. Earth sleeves, for example, can serve as an effective grounding method, but their termination process requires precision measurements and exacting preparation of the stripped area.
In addition to its innovative brush-type connection, SKINTOP® MS-M Brush offers IP 68 protection and resists temperatures up to 100ºC. Until recently, it was available only in metric sizes, ranging from M–25X1.5 to M–110X2.0. This month, we’ve introduced NPT sizes from ¾” to 2”.
