More Product Information
Metal detection position sensors are designed to detect the presence or movement of ferrous materials such as steel bolts, gears, or plates. Available in reed switch or Hall effect configurations, these sensors offer flexible solutions for proximity and position sensing. Reed-based sensors provide simple, low-power operation, while Hall effect versions offer dynamic, solid-state performance with zero-speed detection and enhanced durability. Ideal for industrial automation, safety systems, and heavy equipment, these sensors are available in various mounting styles and electrical outputs to suit diverse application needs.
The latching / bi-stable (1 Form E) reed switch is a magnetically operated switch designed for ultra-low power applications, particularly in battery-powered and energy-sensitive systems. Unlike traditional reed switches, this bistable variant maintains its contact state, either open or closed, without continuous power, thanks to its dual-magnet latching mechanism.
The switch operates by using two permanent magnets: one partially magnetized to bring the contacts near each other, and a second magnet that controls the contact state by reversing its magnetic field. This design allows the switch to remain in either the normally open (N.O.) or normally closed (N.C.) state until actively changed, making it ideal for applications requiring stable switching with minimal energy consumption.
Compact Photo-MOSFET relays in Small Outline Package (SOP) format, offering space-saving solutions for densely populated PCBs. Suitable for surface-mount applications requiring reliable signal isolation and low leakage.
These sensors feature integrated flanges or screw holes for stable mounting on flat surfaces. Designed for rugged environments, they offer consistent performance in industrial, automotive, and automation systems.
High voltage and high-power reed relays are engineered for demanding applications that require reliable switching of elevated voltages and currents. These relays support switching voltages up to 1,000 VDC in compact packages, making them ideal for use in automotive systems, solar energy, EV battery management, medical devices, and automated test equipment (ATE).
For extreme voltage requirements, specialized models are available that switch up to 10,000 VDC, with breakdown voltage ratings reaching 15,000 VDC. These high-voltage relays are trusted in critical medical technologies such as portable defibrillators and electrosurgical generators, where insulation integrity and safety are paramount.
Designed with robust isolation, high dielectric strength, and low contact resistance, these relays offer long operational life and stable performance in high-energy environments. Their compact form factors and versatile configurations make them suitable for both high-voltage isolation and high-current control across a wide range of industries.
Threaded Housing Position Sensors offer a rugged and easily adjustable solution for detecting position, proximity, or motion in a wide range of applications. Available with reed switch or Hall effect technology, these sensors are housed in cylindrical threaded enclosures, typically plastic, stainless steel, or brass, for secure mounting and customizable sensing gaps. Their non-contact operation ensures long-term reliability and resistance to shock, vibration, and harsh environments. Ideal for use in automation, transportation, medical devices, and industrial machinery, these sensors support various output types and connection styles for seamless integration.
Intrinsically safe reed relays and optocouplers are engineered for use in hazardous environments where ignition prevention is critical. Certified to ATEX standards and tested to ensure they do not become ignition sources, even in the presence of short circuits or adjacent component failures—these components are ideal for applications in explosive atmospheres such as mining, chemical processing, refineries, and power stations.
Designed to meet EN50020 safety standards, these relays and optocouplers feature tightly controlled air and creepage paths, high dielectric strength, and low-voltage coil inputs. With a maximum peak voltage of 375 V across input and output, and isolation distances up to 10 mm, they ensure safe operation under overload conditions. The Comparative Tracking Index (CTI) of the plastics used exceeds 175, and internal potting compounds provide additional insulation for long-term reliability.
