Battery Cut-Off Relays from Kissling and Rincon in Compare
Since many years for battery isolation in racing cars we use cut-off relays from the German manufacturer Kissling. With that company been taken over by TE, availability and technical support of that parts has become somewhat poor. So, this year we looked for an alternative and found it at the American manufacturer Rincon.
Even if the two components themselves look quite different, the technical data of the Rincon relay are at least equivalent:
 |
nominal current (make contact cont. current) |
max. cut-off current |
voltage drop | solenoid power consumption | operating temperature range |
| Kissling series 26 | 300A | 3000A | 150mV @ 300A | 350mA | -55 .. +75°C |
| Rincon REC 35 | 350A | 3000A | 125mV @ 250A | 130mA | -40 .. +80°C |
Both products do have one main make contact, a 2 Ampere auxiliary make contact and an integrated free-wheeling diode. They are gastight to standard IP69+ (IP6K9K). Both relays can be mounted position-independent and are vibration proof in accordance with relevant MIL standards. With 410g resp. 407g they are practical equal in weight. The Rincon relay needs a little more space than the Kissling one. In the datasheets Rincon states a minimum 200,000 switching cycles, but not giving detailed load parameters. Kissling specifies 50,000 cycles at 300A resistive load.
Nice side effect: The high current relays from America are currently ca. 20% cheaper than the TE Kissling components and up to now always have been available with pleasingly fast one week of lead time at the European importer.

Important Detail: Connector Labels and Nameplates for Wiring Looms
What's the use of an electric harness if you do not know how to connect? For this, it needs appropriate labels at each plug and a meaningful designation of each single connector. In the past, mnemonics like 'TWAT' may have been clear and distinct for mostly male people working in motorsports - but even with native English speakers it could lead to some irritation. A designation like 'CoolantTemp' or 'WaterTemp' may be the less catchy and more reasonable naming for that particular connector.
And also: What's the use of the most nice label, if it has yellowed after short uptime? Or the lettering has become extincted by usual detergents or the sticker itself decomposed? For our wiring looms we use self-adhesive Nylon tapes or glass silk stickers with temperature resistances up to 120/150°C. They are marked with Dymo or Brother label printers or even with standard office laser printers. This can be done in multiline as well as coloured inscription. These materials adapt smoothly and easily even to waved surfaces. A standard transparent heatshrink gives the necessary further protection.
For sensors and high temperature harnesses we use thin metal foil stickers with Polyimid sheathing. These labels are not easy to build and not as smooth as the Nylon ones. But they shine by perfect pin sharp caption and and classy golden colour. And they are completely free from yellowing and enduring temperature resistant to more than 200°C.
On - Off - Blink: Active Blink Switch for Rain Lights
For backfitting of racing cars with standard fog lights or older FIA rain lights: Three-way switch Aamgard SU28 with integrated blink relay. In the middle position, all is switched off. Knob up and the lamp gets 12V and is continuously switched on. Knob down and the lamp gets controlled by the internal flasher and blinks. The max. load is 8A, so LED rear lights as well as two parallel bulb fog lamps (2x 21 Watt) can be operated. Given by the electronic flasher relay the blink frequency is not affected by the load.

Internal Development: Aamgard Temperature Sensors
Here they are - the first Aamgard Engineering developed motorsport sensors:
- left ATRA: a fast response temperature sensor for air and gases
- right ATRF: a precision motorsport sensor for coolants, fuels, oil etc.
Both sensors provide a measurement range of -40°C to +250°C and very flexible temperature and wear resistant Viton/Teflon electric cables. Both sensor housings are made from anodised aviation grade AW7075 aluminium resp. aviation grade aluminium with PEEK test prod. The ATRA is based on an ultra-fast NTC sensor chip. The ATRF contain a PT100 or PT1000 sensing element, depending by customer requirement.
Variable o-rings (either Viton, Teflon or EPDM) do make both components to nearly all-purpose temperature sensors in motorsports, aerospace and demanding industrial environments.
Livin' in a Box - Powerbox for a Classic Le Mans Racing Sports Car
Electronic PDM inside an 80th Le Mans racing sports car? Rather not! Solid electrics containing modern materials, battery cut-off relay, connectors and circuit breakers? Absolutely! So, the best of both worlds. That way a classic but also modern and reliable power distribution box is done.
Photos, each left to right:
- two interlocking half-shells made from special biopolymer, 3D printed and for improved temperature resistance thermal annealed
- half-shells, reinforced with GFC sheets, water proof glued, riveted and painted;
the component weight is below 50g - internal wiring: battery cut-off relay, fuel pump relays and ETA circuit breakers for each electric circuitry like lighting or engine harness, dashboard etc.
- finished powerbox: M8 screwed contacts for ground (blue), battery positive (red) and starter / alternator (yellow) plus Autosport connectors from Souriau for each individual sub-loom.
