What is this device used for?
This unit is the receiver element of a C4000 Standard safety light curtain system. It is used for access protection at machines and hazardous areas by monitoring a defined protective field when paired with the matching sender.
Is this a sender or a receiver?
It is a receiver. For operation, it must be used together with a compatible C4000 Standard sender with the same resolution/range class and protective field height.
What resolution and protective field height does it support?
This version is designed for 14 mm resolution with a 300 mm protective field height.
What is the scanning (operating) range?
The scanning range is 10 m under typical industrial conditions (alignment and installation conditions can affect achievable range).
What is the response time?
The specified response time is 11 ms (without beam coding, without blanking, and without cascaded/series systems).
What power supply is required?
It requires 24 V DC supply voltage (19.2 V to 28.8 V DC), with residual ripple up to 10%.
What type of safety outputs does it provide?
It provides two PNP OSSD semiconductor outputs. Each OSSD is short-circuit protected and cross-circuit monitored, with a current-carrying capacity up to 500 mA per OSSD.
What electrical connector types are on the unit?
The system connection is a Hirschmann M26, 12-pin male connector (straight). It also includes a Hirschmann M26, 12-pin female extension connection and an M8, 4-pin female configuration connection.
Can it be connected in a cascaded setup?
Yes. The unit supports cascading (series connection) of up to three systems using the extension connection, helping reduce wiring effort in multi-sided guarding designs.
What environmental protection rating does it have?
The enclosure rating is IP65. Rated ambient operating temperature is 0 °C to +55 °C, with non-condensing humidity from 15% to 95%.
How can operators see status or diagnostic information on the device?
It includes an integrated 7-segment display for fast on-device indication during alignment and troubleshooting, along with signaling for operating states.
What mounting options are commonly used with this receiver?
Common mounting hardware includes rigid L-shaped mounting brackets and rotatable bracket kits. Examples of commonly paired accessories include mounting kit 1 (BEF-3WNGBAST4) and swivel/side bracket sets such as BEF-2SMMEAKU4 and BEF-1SHABAZN4, depending on the mechanical layout.
Does it support external device monitoring and restart interlock?
Yes. It supports external device monitoring (EDM) and restart interlock (RES) functions to help integrate the light curtain into machine control circuits.
Are there expansion functions available with additional modules?
In combination with a compatible switching/amplifier module (such as UE402), additional functions like bypass, operating mode switching, and PSDI mode can be implemented where required by the application.
