UHV Compatible Optical Limit Switch

Confirm Positioning Under Ultra High Vacuum

The Model OLS is available for use as a "HOME" or "position confirmed" optical limit switch based on proven Honeywell LED and optical transistor devices. Similar to the widely used Omron SX series photomicrosensors, but fabricated from ultra-high vacuum (UHV) compatible materials and hermetically sealed components, these limit switches are turned on/off by a flag interrupting a narrow beam which provides a very reliable, non-mechanical repeatable switch. The signal conditioning PC board on the OLS will convert signals from the sensor. The signal is ready for interfacing to your PLC or other process control instrumentation. The OLS will operate in temperature ranges from -55°C to 125°C.

Applications include use on linear stages, rotational stages, or any other device operating under UHV conditions requiring a switch to confirm positioning. Feedthroughs and wiring kits are available.
