Hamlin introduces new Reed Switches MACD-14 and MASM-14

Small profile, 14mm reed switches with close differential

MACD-14 and MASM-14 reed switches allow for smaller range of movement in proximity sensing

MACD-14 (leaded) and MASM-14 (surface mount) are sub-miniature, normally open switches with a 14.00mm long x 2.28mm diameter (0.551” x 0.090”) glass envelope capable of switching 200Vdc at 10W with close differential. Available sensitivity range is 10-30 AT. The reed switches have a high insulation resistance of 10¹⁰ ohms minimum and a low contact resistance of less than 100 milli-ohms. These devices are ideally suited to position, proximity, float position sensing for liquid level, industrial controls, office equipment, home appliance, and telecom applications.
