We have been manufacturing reed switches for over 30 years, and are presently supplying some of the needs of every major reed relay, sensor and security manufacturer. Aleph has more than 30 different types of reed switches that include general applications, high power, high voltage, high insulation resistance, low thermal EMF and mercury wetted. Most are available in form "A" or form "C". Using these reed switches we manufacture a full line of reed relays that include mercury wetted, high power, high voltage, high insulation resistance, low thermal EMF, RF relays and a new line of surface mounted relays ( SMT ). Aleph is a leading manufacturer of Opto Sensors ( interrupter, reflective and actuator type ), Magneto Resistive, Inductive, Thermal ( reed switch ), Magnetic Proximity ( reed switch ) and Deceleration/Crash type sensors. Our security products are considered some of the best in the world. We manufacture and distribute Passive Infrared Detectors, Photoelectric Beams and Magnetic Contacts. In addition to our standard catalog products, we can custom engineer and manufacture sensors, reed relays and security products designed to meet your exact specifications and performance requirements.
