JMSW-26XM is a Type JMS electromagnetic relay designed for communications and instrumentation applications. The relay features a coil resistance of 3300 ohms ±10% at 25°C with a nominal voltage of 26.5 VDC, must-operate voltage of 14.0 VDC, and must-release voltage range of 1.4 VDC to 8.0 VDC maximum. It provides low-level contact ratings up to 1A at 28 VDC resistive with an operational life of 100,000 cycles, and operates with a maximum response time of 4 ms, release time of 2.0 ms, and contact stabilization time of 2.0 ms. The relay is qualified for harsh environments, withstanding vibration from 10 to 3000 CPS at 30 g's, shock loads of 75 g's for 6 ms duration, and operating temperatures from -65°C to +125°C. These specifications make it suitable for aerospace, military, and industrial control systems requiring reliable switching performance under demanding conditions.
