SL-V safety light curtain has visible indicators
A
Keyence (UK) product story
Edited by the Engineeringtalk editorial team
Jul 30, 2009
The new SL-V safety light curtain from Keyence incorporates highly visible indicators to facilitate setup and to see the current operating status.
The tough, slim, space-saving body conforms to IP-65 and IP-67 rating standards, which allow the sensor to work well in harsh environments.
The edge-to-edge mounting and side-exit cabling allow the curtain to fit into equipment, with the cabling tucked away from danger.
Operators can immediately determine whether the curtain is active.
This prevents situations where the beam is accidentally blocked.
The indicators emit green lights when the beam axes are properly aligned, facilitating setup.
To facilitate troubleshooting, red lights indicate the location of a curtain blockage if the beam axes become misaligned, dirty or blocked.
Edge-to-edge detection and side-exit cabling enable space-saving mounting and no dead zone.
Conventional models need to be mounted externally or require special custom guards to protect the dead zone at the bottom of the light curtain.
Standard, thin, L-shaped, E-to-E, tough-standard and space-saving brackets are available.
Up to three curtains (or a maximum of 240 beams) can be connected in series.
Curtain lengths range from 150mm to 2,390mm up to three in total.
The SL-V includes an automatic interference reduction function to stabilise operations without the requirement for special wiring.
The heavy-duty SL-V can be used in environments where workpieces often strike the unit.
The aluminium-framed brackets ensure that there is no damage from shock and that the optical axes do not become misaligned if struck by an object.
An optional waterproof cover protects the front of the sensor from stains and splatter.
The clear lens cover is recessed for added protection.
An all-in-one built-in controller saves costs on additional units that would be required for conventional light curtains.
The SL-V has a built-in external device monitoring function, enabling Category 4 devices to be handled without a safety relay unit.
It also has built-in muting and interlock functions so that a safety control circuit can be constructed without a dedicated controller.
