Product Description

Assemtech GC3817 (30-40AT) is a Single Pole Normally Open (SPNO) PCB-mounted Reed Switch designed to switch loads up to 3 A and voltages up to 400 V ac/dc. It features rhodium-plated contacts hermetically sealed within a gas-filled glass envelope that protects against environmental contaminants and ensures consistent performance.

This reed switch operates effectively over a temperature range from -40°C to 125°C, making it suitable for harsh industrial and automation environments. The switch offers fast response times, with a release time of 0.1 ms and an overall operating time including bounce of 0.5 ms, assuring precision switching in electronics and control systems.

Measuring 24.5 mm in length and 3.8 mm in width, this component is optimally sized for printed circuit board (PCB) installation and can be actuated by electromagnetic or permanent magnets. The mechanical life rating of 10^8 operations guarantees long-term reliability for industrial, laboratory, and automation applications.

Constructed with durable rhodium contacts, it delivers low contact resistance (100 mΩ) and low switching power loss (60 W max), supporting stable and efficient electrical control. This product complies with ISO standards reflecting quality assurance and is manufactured in India.

Rhodium-plated contacts provide excellent conductivity and resistance to corrosion. Sealed glass envelope hermetically protects the switch internals against moisture and contaminants. Fast electromagnetic actuation with low switching noise and bounce.

Broad operating temperature range suitable for diverse industrial environments. Compact form factor facilitates easy integration into PCB-based electronic assemblies. Designed for extended mechanical life with consistent switching performance.

Complies with relevant ISO standards ensuring product quality and reliability.

This single pole normally open PCB Reed Switch from Assemtech is ideal for applications in industrial automation, electronics manufacturing, control systems, sensors, and instrumentation. It supports reliable switching in devices requiring magnetic actuation with high endurance and precision.
