Tubular Proximity Sensor with Smaller Footprint for Automation Applications

January 25, 2010
The two new cylindrical (tubular) proximity 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 can be used in automation, control, or detection in a broad array of applications – including safety, security, alarm, equipment, and 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 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 diameter and 0.750 inch length. The Form C (Single Pole Double Throw) or changeover reed switch has similar housing and dimensions. Both sensors are based on the company’s reed switch technology and operate using a permanent magnet or an electromagnetic coil. These new sensors have an operating distance of .250 inches and are rated at 2 watts. The maximum operating temperature is 105 degrees C while the storage temperature range is -40 degrees to +105 degrees 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.
