Standex Detect - Ultraminiature Reed Switches (<8mm)
Ultra-Compact Reed Switches for Precision Electronics
The ultraminiature reed switch series offers some of the smallest magnetic switching solutions available, with glass body lengths starting at just 3.95 mm. These switches are engineered for precision and reliability in space-constrained environments, making them ideal for miniaturized electronics and high-density circuit designs.
Despite their compact size, these switches maintain strong electrical performance thanks to advanced contact materials and hermetically sealed construction. Their flat lead design supports automated assembly processes such as surface mounting and tape-and-reel packaging, enabling efficient integration into high-volume production lines.
Commonly used in semiconductor testing, medical devices, telecommunications, security systems, and automotive electronics, these switches provide dependable magnetic actuation in applications where size, sensitivity, and durability are critical.

Dual In-line Package (DIP) Photo-MOSFET relays offering easy through-hole mounting and robust performance. Commonly used in industrial control, security systems, and test equipment.
Ultraminiature reed relays are engineered for high-density, low-profile applications where space and performance are critical. With package heights as low as 3.4 mm and footprints under 8 mm, these instrumentation-grade relays are among the smallest in the industry. Ideal for tightly stacked matrices and compact PCB layouts, they offer high insulation resistance, low contact resistance, and reliable switching for billions of operations.
Our surface mount SMD reed switch products feature a bare, hermetically sealed glass envelope designed for reliability and precision. With five distinct surface mount lead designs, these switches offer enhanced flexibility for various PCB layouts and applications.
Magnetically actuated, these reed switches are ideal for both switching and sensing functions across a wide range of industries, from automotive and medical to industrial and consumer electronics.
We offer nine different switch models, with glass lengths starting as small as 7 mm, and a variety of switching configurations. Choose from power ratings up to 100 W and switching voltages reaching 1,000 VDC, tailored to meet your specific performance requirements.
For streamlined manufacturing, our SMD reed switches are typically supplied in tape and reel packaging per IEC 286/Part 3, making them compatible with automatic pick-and-place equipment.
- The DF241 is characterized as a Small Low Angle Dark Field ring light.
- Precisely aimed LEDs provide a very low angle of incidence, radial illumination pattern.
- A scratch on a sheet of glass is a good example of a defect that can be detected with a low-angle dark field illuminator.
- With a light intensity of 24kLux at a working distance of ½” (12.5mm), the DF241 is perfect for imaging problems limited to a small field of view.
- A 25mm field of view is standard with an optional field of view of 35mm.
- Available in a range of wavelengths from UV to IR.
*Engineered to provide comparable optical characteristics to our previous RL1360.
Designed for applications requiring current handling above 1 amp, these relays offer low on-resistance and high thermal stability for power control and motor drive systems.
Side Mount Liquid Level Sensors offer robust and versatile solutions for accurate fluid level monitoring. Designed with flexible mounting options, including external/internal threads and grommet inserts, these sensors feature separate float/sensor designs to minimize leak paths. Ideal for automotive, industrial, and medical applications, they support both Normally Open (NO) and Normally Closed (NC) configurations, with power options up to 100W. Integration is simplified with cable harnesses and connector options, making them a trusted choice for OEMs and Tier 1 platforms.
Threaded housing sensors allow precise positioning and easy installation using lock nuts. Suitable for both Reed and Hall effect technologies, they are ideal for applications requiring adjustable sensing gaps.
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.
