DIN RAIL Terminal Block Market Split - By Region (2017)

  • APAC dominated the global DIN RAIL terminal block market, with a market share of around 32 percent in 2016. Increasing industrialization and demand for HVAC in countries, such as China, India, South Korea, and Indonesia, are expected to drive the terminal block market in this region 
  • North America is also one of the major regions for terminal blocks market, due to the presence of prominent manufacturing companies in this region. Approximately 60 percent of the terminal blocks used in the US are of DIN type
  • The DIN RAIL terminal block market was moderately consolidated with the top five players constituting to around 48–50 percent of the market share in 2016. Leading players in this industry have typically increased their market share through strategies, such as mergers, new product developments, partnerships, collaborations, and business expansions, etc.
  • For example, in 2001, ABB acquired Entrelec; in 2003, Rockwell Automation Inc. signed a strategic alliance with Weidmüller Holding AG for terminal blocks

Global DIN RAIL Terminal Block - Drivers and Constraints

Drivers

  • Increasing demand for DIN RAIL from APAC and American markets acts as a key driver for this segment 
  • Increasing industrialization and demand for HVAC in countries, such as China, India, South Korea, and Indonesia, are expected to drive the terminal block market in this region
  • Rapid growth of industrialization, factory automation, and instrumentation over the past 3–5 years were the main factors driving this industry
  • Technological advancements in terminal blocks, with respect to termination technology, have increasingly resulted in more compact designs, thereby driving replacement demand for this product

Constraints

  • Constant innovations are needed in this market segment
  • Such innovations are expensive, and thereby make the product costly for the end user. This acts as a key constraint in this industry

Recent Technology Developments

Space Saving with High Wiring Density

  • In August 2016, Phoenix Contact introduced push-in connection technology- based PT 2,5/S-QUATTRO series four-position terminal blocks, which occupied the same space as that of the company’s two-position terminal blocks, thus allowing for a high wiring density without losing space across the DIN RAIL
  • These terminal blocks have a provision to connect up to four 12 AWG conductors in one-feed through terminal block, and they have a double function shaft for easy potential distribution with plug-in bridges and large-surface marking options

Floating Property

  • In August 2012, WECO introduced the SMarTconn family of surface mount terminal blocks
  • These terminal blocks are designated as the 930-D-SMD Series of terminal blocks and are available in 2–12 poles
  • These terminal blocks are constructed for reflow processes used in automated pick-and-place assembly systems
  • The 930 D-SMD is the only 3.5-mm pitch terminal block, which embeds a floating property in the terminal contact bodies
  • The floating pin design ensures total co-planarity adaptation to the PCB surface, and it fully eliminates the coefficient of thermal expansion mismatch effect

High Performance

  • In April 2012, Cooper Bussmann offered Short Circuit Current Ratings (up to 200 kA) and exceptional wiring flexibility with its new line of DIN-RAIL terminal blocks, having high performance and flexibility for unmatched power distribution possibilities
  • These terminal blocks are made of self- extinguishing UL 94V0 plastic, which provides high impact strength and superior electro-mechanical properties, and they are as per UL 1059, cURus, and IEC 60947-7 standards

Space Saving

  • In March 2016, Wieland Electric Inc. expanded its wipos series of DIN RAIL power supply modules, with a new compact design for control cabinet applications 
  • This new design has UL, CSA, CE as well as approvals for hazardous locations (Class 1, Div. 2) and shipboard installations (Lloyd’s Register)
  • The wipos PS3 series power supplies are rated for 24VDC/5A to 40A output power, with the capability for 120 percent power boost for 10 seconds, and accept a wide range of input voltages (320–576VAC/450–810VDC) 

Space Saving with Reduced Engineering Time

  • In July 2016, Weidmüller announced the release of a new generation of terminal blocks, the Klippon Connect A-Series, which would save space and cut engineering times by up to 75 percent
  • The system includes both clamp and screw connection technologies and offers error-free wiring and faster marking during the planning, installation, and operating phases
  • The screw connection technologies offer a choice of clamping yoke or stud connection designs, while the spring designs are equipped with push-in or tension clamp technologies
  • Push-in connections represented just 6 percent of terminal connections in 2015, nonetheless Weidmüller predicted that they would account for around 18 percent of sales by 2025, while tension clamp connections are expected to fall from 25 percent to 16 percent over the same time period
  • Screw terminals will drop slightly from 57 percent of the market in 2015 to 54 percent by 2025
