HERMETICALLY SEALED MICROSWITCH ES SINGLE POLE, CHANGEOVER TYPES 83 151 (150C) AND DERIVA TIVES PRESENTATION This is the basic comporent for our whole range of standard 1-pole and 2-poIes hermetically-sealed limit switches plus the 3-poIes version (special Umit Switches). The CROUZET hermetic microswitch combines a snap-action switching system with high resistance to shock and vibration in an hermetically sealed miniature case which encloses an atmosphere of inert gas around its contacts, ideal for switching very Iow level circuits and higher currents also. The meticulous care taken in the manufacture of this hermetically sealed cell in terms of assembly processes, cleanliness of components as well as inspection procedures, result in a product which is ideal for operation in severe environments where a high level of reliability is essential. The CROUZET hermelically sealed cell is particularly well suited to sectors such as Aerospace, Armaments, Marine, Nuclear, etc. Solder Insert gas filling Solder Compressed glass seal Diagram of snap-action device ESSENTIAL CHARACTERISTICS * Switching power from 1 mA to 7 A. * Operating temperature: -55C to 150C : Type 83 151 -55 C to 250C : Type 83 1512 * Operating pressure : 1 bar : Type 83 151 From 2 to 6 bars : Type 83 1515 * Vibration resistant up to 80 g. * Shock resistant up to 200 g. * High level of hermetic sealing: Leakage < 1 x 10-6 cm3 He/S * Long life: 200,000 cycles. * Small size: o 11 x 16. * Numerous single pole and multipoles operating and fixing options. 7 For further information, contact us. www.crouzet.com DISTINCTIVE CHARACTERISTICS Mechanical strength F.daN 8 7 6 5 4 3 Tolerated overtravel forces 2 No abrupt increase in the total travel of the device is noted under rising overtravel forces of up to 80 N. On return to a normal overtravel force of 20 N after these measurements have been carried out on one and the same device, the total travel will be observed to have varied only very little (low permanent set). The device can be damaged if the overtravel force is pushed up to 150 N.

Increase in operating force 0 200 400 600 760 P (mm Hg) -1 -2 The force values of our hermetically sealed microswitches are influenced by ambient pressure and temperature; we give the value, for the base cell, for the increase in operating force ( OF) as a function of these two parameters. The characteristics are stated for normal temperature (23C) and atmospheric pressure at sea level (760 mm Hg). Our hermetically sealed microswitches can be used from atmospheric pressure to absolute vacuum; some variants allow use at higher pressures.
