>>Precautions for use

Global safety

The SF2-EH series complies with the IEC 61496-1/2 international standards, so that it can be used in different countries throughout the world.
・CE marking based on Machine Directive and EMC Directive has been obtained. [Type 4 based on IEC (EN) 61496-1/2, and Category 4 based on EN 954-1]
・UL and C-UL listings (IEC 61496-1/2) which are required for use in the United States and Canada have been obtained.
・This series is also compatible with equipment conforming to OSHA (1910. 212/217), ANSI (B11.1lB11.20) and ANSI/RIA 15.06 regulations.

Pursuit of safety

It uses two independent CPUs, which mutually check the safety conditions. High reliable fail-safe design includes dual circuits for signal processing and outputs.
Furthermore, in order to ensure safety, FMEA (Failure Mode & Effect Analysis) has been used to prove safe operation.

Wide area 1,580mm x 10m

It has a wide sensing area with a sensing height of 1,580mm max. (80 beam channels) and a long sensing range of 10m.
Just one sensor can cover an area where previously 2 sensors had to be used.

Sensors connectable in series

Using the optional cable (SF2-CSL□) for series connection, maximum 4 sets of sensors with a total of 192 beam channels can be connected in series.
For example, in case of mounting the sensors in the front, as well as, both sides of a danger region, previously separate wiring was required for 3 sets of sensors. Now, wiring equivalent to that for only 1 set is required; thus, troublesome wiring and cost are reduced.

Wide variety

There are 13 models of sensors with sensing height ranging from 220mm (12 beam channels) to 1,580mm (80 beam channels). The sensors can be selected to suit the monitoring area of the equipment in use.
Further, PNP output equivalent type as well as NPN output equivalent type are available.

Up to 12 sets mountable

In case of series connection or parallel connection, interference can be prevented for up to 4 sets, respectively.
Further, in case of series and parallel mixed connections, up to 12 sets (total of 192 beam channels) can be mounted.

Beam spread angle ±2.5° or less

Since the beam spread angle is narrow (±2.5° or less), it reduces the effect of reflection from walls and interference from extraneous light.

Exclusive controller not required

Since an exclusive controller is not required, there is no need to provide space for it.
Further, the PNP output equivalent type can be combined with an optional safety relay unit to create an intrusion detection system.

Solid aluminum case

All models have a solid aluminum case with a thickness of 3mm. This case is much stronger than previous cases, so that the sensors can be used with even greater confidence.
