Hongfa Industrial Relays

An Industrial relay is a relay used for switching power circuits in industrial applications, from 5 Amp up to 20 Amps. Industrial relays uses an electromagnetic coil to attract the relay armature which can contain 1 or several contacts. Industrial relays contain a strong electromagnetic coil and spring mechanism to overcome the large electrical forces generated when switching industrial power circuits.


Typical applications for Industrial are Vending machines, Lighting control, Industrial Heat & Ventilation applications, Pump control and Control Panel switching and general control applications.


Switchtec carries extensive stock of the Hongfa range of Industrial Relays, whose range offers one of the most comprehensive portfolios of Industrial Relays. These including SPST, SPDT, DPST, DPDT, 3PDT and 4PDT with Coil Voltages ranging from 5V to 60VDC and 24V to 230VAC. The most popular Coil Voltages being 12V & 24VDC and 24V & 230VAC with the most common contact ratings being 5, and 10 Amp.


Hongfa have a full sel ection of Industrial relays with mounting options including PCB industrial relays, and Plug in industrial relays formounting into Din Rail Sockets. These are available SPST, SPDT, DPST, DPDT, 3PDT and 4PDT combinations.


When specifying an Industrial relay, the following options need to be considered, Coil Voltage (5 V, 12 V, 24 V 48 V,…), Termination Style (PCB, or Plug in) and Maximum Contact Current (from 5 to 10Amp) Contact arrangement SPST, SPDT,DPST, DPDT, 3PDT and 4PDT.
