High Sensitivity Photo-Electronic Safety Device for Machine

1. Fast response time <20ms. 2. LED indicator,easy to algin, display real-time working status. 3. Auto self-checking function.

1. Fit for kinds of Machinery Fields

*Comprise of emitter(transmitter), receiver, controller, connection cables and mounting fittings.

 2. SNB series's specification 

* Fast response time <20ms.

* LED indicator,easy to algin, display real-time working status.

* Auto self-checking function to avoid output wrong signals to control circuit.

* Dual relay output to guarantee high safety.

* Reset function: When any beam(one or more) is obstructed, equipment can't run till press "Reset" Button, light passing recovers as well.

* Easy connection: End lid with aviation plug in connector and cable.

* High anti-interference: not affected by electromagnetic signal, strobe, welding arc and other periphery light.

 Anti-vibration: adoption of several shock-absorbers like rubber washer, damper to reduce vibration by the greatest extent.
