The LSTF50-ZX model is currently only available for high volume OEM applications. This model is designed for use as a fast process shutter and quick reaction safety interlock. The inherent speed is achieved with minimum electrical power requirement. This model is used routinely in application that operates 24/7/365, accumulating billions of cycles. It is our highest reliability technology. Controller choice affects switching speeds. The solid copper package efficiently manages thermal flow, delivering the heat to the mounting surfaces.
Compatible system controllers are CX3000B, CX4000B or user-built circuits designed around 24 VDC. Specification are for use with a typical 24 V capacitor discharge or PWM circuit.
See the “Mechanical Drawing” tab for dimensions. Also see the “Application Notes” tab on the home page menu for important operational issues including: thermal mounting, user-built circuits, polarization, lifetime, jitter, vacuum operation, and contamination.
Special considerations for this model are primarily thermal mounting. The Output Aperture face is the ideal surface for high heat loads, and the bottom threaded surface for lower heat loads.
Restricted use for this model include close proximity to high magnetic fields and strict observance of optical power rating. Environments subjecting shutter to large size particles could inhibit shutter motion.
