Small and pressure-resistant
- Ideal for limited installation space
- Excellent for mounting in and on windings
Safe, reliable, durable
- Constant contact pressure over the entire temperature range
- For type 06, H6, RH double contact switch-off (NC contact) / switch-on (NO contact) due to higher current intensity
- Over 70 tests during production ensure quality
- Worldwide licences
- Very fast switching; therefore short duration of the arc effect on the contacts
Temperature sensitive
- Reproducible switching temperature due to mechanically and electrically unloaded bimetallic disc, factory-set nominal switching temperature (NST)
Fast response
- Good heat transfer to the rear derailleur due to very low switch mass
- With type P1 and W1 short switch-off times due to a defined series resistor RS
- Flexible use
- Wide supply voltage range with the exception of type R6,
- Comprehensive range of wires/strands
- For types P1 and W1, the heat output required for self-retaining is automatically regulated by a built-in PTC resistor RH (no overshoot)
Bimetal switch
When the factory-set nominal switching temperature (NST) is reached, a bimetallic disc suddenly jumps from its stable starting position to a stable end position and actuates the rear derailleur.
Opener:
Types 01, Z1, P1, W1, 06, R6, H6, RH
Kontakte werden getrennt und unterbrechen den Stromkreis = >direkte Abschaltung
Closers:
Types 02, 08, 09
Contacts are closed and activate a circuit = > e.g. activation of signalling devices.
Resetting:
Types 01,02, Z1, 06, 08, H6
If the temperature falls below the factory-set reset temperature (RST), the rear derailleur returns to its stable starting position.
Self-holding:
Types P1, W1
An integrated PTC heating resistor RH is located parallel to the switching mechanism. Once the contacts have opened, its heating power keeps the switching mechanism above the reset temperature until the supply voltage is interrupted. This function is used when automatic switch-back after overheating and subsequent cooling is undesirable or not permitted. Inspection and/or service required!
Defined current sensitive:
Types Z1, W1
