New Hall Effect sensor from Hamlin

View Press Release PDF

Hamlin Electronics has introduced a new Hall Effect mini-vane sensor to its range of magnetic sensing products. Because it uses non-optical sensing technology, it is immune to the effects of dust, dirt or extraneous light sources but still provides a high-speed output.

The Hamlin 55085 has the sensor and magnet contained in a single housing with a base size of only 28mm x 9mm. The sensor is activated whenever the ferrous vane passes through a sensor slot and provides an extremely fast switching rate of up to 10KHz. Because the sensor is solid state it does not suffer from mechanical wear and is unaffected by harsh environments.

The unit is reverse and over voltage protected, has built-in temperature compensation and is ideal for applications such as position, angle, limit and shaft rotation sensing, security systems, linear actuators and magnetic encoders. The sensor can be directly soldered into a PCB and can be further secured using the two 3.25mm diameter fixing holes. This robust product has a rated operating temperature range between -40°C and +100 °C. Hamlin Electronics was formed in 1949 and has been a Key Automotive Group affiliate since April 2003. Today it employs over 1,000 people worldwide with manufacturing facilities in the UK, USA and Mexico. The company also has European and North American engineering facilities and a global sales network. Hamlin¿s manufacturing and engineering operation in the UK started in Diss, Norfolk in 1976.

In 2003 Hamlin signed an agreement with industry leading Swiss, programmable Hall sensing element manufacturer, Micronas. The agreement gives Hamlin unique level of access to Micronas products, engineering and support to aid the implementation of Hall effect technology in to many of its automotive and industrial custom sensor solutions as well as a range of catalogue products.
