This is an overview of the Kuhnke range of industrial relays. These products are found in medical, railway, and power generating applications as well as industries such as printing, textiles and automation. Please click on the image to view the PDF datasheet.
Other Kuhnke relays can be seen in the panel relays section of this web site, which shows the individual part numbers for the most popular relays used today in control panels, interface technology and automation systems.
Plug in and PCB versions. Older models may have AgCdO contacts indicated by a C in the part number. Twin contact options. Coils are mainly 24VDC, but some other variations are possible. Socket part number is Z320.02.
Kuhnke universal timer relays have specified functions for pull in, switch off, blinker and wiper. There are 4 time ranges and three standard voltages creating over 50 options. Ideal for OEM's requiring a non-tamper product.
Kuhnke universal latching relays work by energising one of the 2 coils for more than 50ms. 8 coil voltages. EB4 plugs into a base, and EG4 version is for printed circuits.
Plug in for socket or solder connection. 1A2 and 1A4 can be used with socket Z382.02. Many options include different contact materials, twin contacts and a blow out magnet for switching heavy DC loads. Mainly 24VDC, but some other voltages are available.
Plug in for socket or solder connection. Standard option is 1H.100.24DC. There is only one version in this design.
Kuhnke navigation relays plug into standard 8 pin sockets, and are used to monitor DC or AC filament bulbs (and similar loads). There are 85 variants to suit 14 supply voltages with loads from 10W - 200W.
Kuhnke power relay, once available with different contact materials, now supplied with hard silver only (PAS). Mainly 24VDC coil. Suffix S (PASS) indicates auxiliary contact, and suffix M at the end of the whole part number indicates blow out magnet.
Kuhnke UA relays use sockets Z352. Both 8pin and 11pin versions have hard silver, single or twin contacts, with or without gold cladding. A special purpose relay that is still available in 5 coil voltages.
Kuhnke UB relays were 2 pole or 3 pole with a variety of contact materials. Now only the UB3-230VAC1L is available as a replacement product. All others are obsolete.
Kuhnke UB range was the forerunner to today's UF relay (see this site's panel builder section). It is only available in one of its original options. This was a flat blade type.
Kuhnke 600 series process relays include analogue to digital converters, PT100 analogue converters, and frequency analogue converters.
Kuhnke 500 series monitoring relays provide 1C/O output for under or over voltage, single or 3 phase, and for undercurrent or overcurrent. The 6 basic versions are available for 24VDC, 115/24VAC, or 230/24VAC supply.
Kuhnke 1500 series monitoring relays perform similar functions to the smaller Kuhnke 500 series, but with 2C/O outputs. There are more options for monitoring range, and supply voltages.
Older models of Kuhnke industrial relays invovlee FA, IX, IY, & HF, some versions of which are obtainable on a parts replacement basis for a limited time.
If you are looking for any other Kuhnke relay product we may be able to help trace a replacement, or re-engineer with the help or original specifications.
