Hermetic Switch Introduces New Proximity Sensors

 

12 January 2010, Chickasha, OK (USA) - Hermetic Switch, Inc., a designer and manufacturer of reed switches, proximity sensors and other switch technologies, has introduced two new cylindrical (tubular) proximity sensors. Hermetic’s PRX+3800 (Form B) and PRX+3900 (Form C) magnetic sensors deliver all the advantages of reed switch sensing technology but with smaller physical dimensions than previously available. These new sensors respond to the market need for components with smaller footprints, as size reduction trends continue in the systems and devices utilizing proximity sensors. These new sensors from Hermetic can be used in automation, control, or detection in a broad array of applications – including safety, security, alarm, equipment, machinery, manufacturing and processing systems – in industrial, commercial, medical, corporate, government or military settings.

 

Specific applications vary widely and include any number of situations – including extreme environments – where reliable and potentially long-term proximity monitoring is desired but physical contact must be avoided (between the sensor and the object being sensed).

 

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 0.125 inch (3.18mm) diameter and 0.750 inch (19.05 mm) 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.

 

These new sensors have an operating distance of .250 inches (6.35 mm) and are rated at 2 watts. The maximum operating temperature is 105°C while the storage temperature range is -40°C to +105°C. The sensors are insensitive to electrostatic discharge (ESD) which makes them ideal for applications where ESD is a concern. Custom wire and connector configurations are available upon request. See below for data sheets.

 

Pricing for the PRX+3800 and PRX+3900 is in the range of $5.00 to $7.00 each (US Funds) depending on quantity.  Pricing is also affected by additional options such as custom sensitivity, custom configuration, and special wiring or connectors.
