Hermetic Switch (distributed in Australia by Koloona Industries) announced two cylindrical (tubular) proximity sensors.

The sensors are based on the company’s HSR-502R reed switch technology and operate using a permanent magnet or an electromagnetic coil.

The PRX+3800 is a Form B (Single Pole Single Throw Normally Closed) reed switch contained in a temperature resistant cylindrical (tubular) housing, which has a nominal size of 3.18mm diametre and 19.05mm length. The PRX+3900 is a Form C (Single Pole Double Throw) or change-over reed switch with similar housing and dimensions.

Both sensors are based on the company’s HSR-502R reed switch technology and operate using a permanent magnet or an electromagnetic coil.

Designed for industrial, commercial, medical or military use, Hermetic's sensors have an operating distance of 6.35mm and are rated at 2W. The maximum operating temperature is 105°C while the storage temperature range is -40°C to +105°C.

Hermetic said the sensors are insensitive to electrostatic discharge (ESD) which makes them ideal for applications where ESD is a concern.
