Crouzet 81290501
TME has introduced pneumatic microswitches from Crouzet, which, due to lack of electromagnetic contact, are claimed to be longer lasting and more dependable than standard electric microswitches.
The Crouzet 81290501 has no configuration and is normally open.
The Crouzet 81290001 with NC configuration and is normally closed.
These pneumatic elements measure 30 x 16.5 x 10.7mm; have a nominal operating pressure of 2 bar; pressure force used for switching at 6 bar of less than 50g; operation temperature range from -10 to 60C; and 170Nl/min flow at the pressure of 4 bar.
Capable of working with both air and inert gases, the microswitches have mechanical durability at the pressure of 6 bar, lasting up to around 10 million cycles; a response time of less than 15ms; connections 2 x 2.7mm; and a weight of 8.5g.
There are two types of actuators/levers available for the above microswitches.
These are Crouzet79215741, a 25.4mm-long straight lever; and Crouzet70507529, the same equipped with a roll.
According to TME, operation without the risk of an electric arc being produced during connection and disconnection makes pneumatic elements more resistant than their standard electric counterparts.
