MURRELEKTRONIK M12
Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang MURRELEKTRONIK M12 dari 3G Electric.
What is the difference between EXACT12 and MVP12 Murrelektronik M12 junction blocks?
EXACT12 blocks are general-purpose passive junction blocks available in plastic or nickel-plated zinc die-cast housings, with IP65 or IP67 ratings. They come in 4- or 8-port configurations with 4- or 5-pole M12 female connectors. MVP12 blocks include a stainless steel variant (MVP12 Steel F&B) rated IP69K for washdown environments. Both series are passive and require a terminal cap for connection to control systems.
What IP ratings are available for Murrelektronik M12 junction blocks?
Standard EXACT12 and MVP12 METAL blocks are rated IP65 or IP67. The MVP12 Steel F&B variant is rated IP69K, suitable for high-pressure washdown applications. These ratings indicate protection against dust ingress and water jets, with IP69K specifically designed for steam cleaning and high-temperature water.
Do Murrelektronik M12 junction blocks require a separate terminal cap?
Yes, passive junction blocks without homerun cable (e.g., SKU 852UF8, 852UE4, 852U92) require a separate terminal cap for wiring to the control system. For example, the 8-port 5-pole block (852UF8) uses a 21-pole screw terminal cap, while the 8-port 4-pole block (852UE4) uses a 14-pole screw terminal cap. Homerun cable variants include a pre-wired cable for direct connection.
What is the electrical design of Murrelektronik M12 junction blocks?
All listed Murrelektronik M12 junction blocks feature PNP (sourcing) electrical design. This means the output switches the positive supply voltage to the load, which is common in sensor applications with PLC inputs. The blocks are passive and do not include active electronics.
Can Murrelektronik M12 junction blocks be used in food and beverage applications?
Yes, the MVP12 Steel F&B variant (e.g., SKU 852UH2) is specifically designed for food and beverage environments. It features a stainless steel housing and IP69K rating, making it resistant to washdown with high-pressure hot water and cleaning agents. Standard EXACT12 blocks are not rated for such conditions.
What cable lengths are available for Murrelektronik M12 junction blocks with homerun cable?
Homerun cable variants are available in lengths such as 3 meters (e.g., SKU 852UC8) and 5 meters (e.g., SKU 852UE8, 852UA7, 852UH2). The cable is pre-attached and terminated with a flying lead for connection to the control system. Non-homerun variants require a separate terminal cap.
