 > Caps

Standard cap, material aluminium (code T)
Use with bracket #4

 

 

Stainless steel cap (code V) for large loose bracket #3 or fixed bracket B +angle

Deviations from standard controls (caps, terminals, fixings) on request.

Especially for electronic applications with voltage 6…120 Vac / 6…30 Vdc and current 10…100 mA, there are switches with crossbar- contacts available. (code P)

Controls as single operation device (SOD) up to 150°C and reset temperature -35°C are available (type 81ES).
