Definitions See Definitions and Operation Principles in chapter 1 of the Mayser catalogue. Intended use A Safety Edge detects a person or part of the body when pressure is applied to the actuation area. It is a linear tripping device. Its task is to avoid possible hazardous situations for a person within a danger zone, such as shearing and pinching edges. Typical areas of application are door and gate systems, moving parts on machines, platforms and lifting devices. Safe operation of a Safety Edge depends entirely on - the surface condition of the mounting surface, - the correct selection...

Tip For the risk and safety assessment of your machine, we recommend ISO 12100 “Safety of machinery – Basic concepts, general principles for design” . The downstream control must comply with at least ISO 13849-1 category 3 and have inputs for the reliable evaluation of the status of the normally closed Safety Edge. Effective actuation area The parameters X, Y, Z, LNE and the angle α describe the effective actuation area. For the effective actuation area, the following applies: LWB = LSL - 2× LNE Parameters: LWB = Effective actuation length LSL = Overall length of the Safety Edge LNE =...

Available lengths 30 cm to 6 m SL/NC II Bend angles and bend radii Bend angles Bend angles are not possible on the normally closed Safety Edge SL/NC II. Note: Bend angles and bend radii are not part of the EC design tests Bend radii Normally closed Safety Edges with a bend radius are only possible with the aluminium profiles C 36 and C 36S. The aluminium profile must be prepared for this at our plant. Installation position ATTENTION No pressure may be exerted on the NC Safety Edge in non-operative mode. The installation position can be selected as required, i.e. all installation positions A...

Connection Cable exits 90° exit Distance to front end each 60 mm Standard (S1) S2: 2 cables Lateral exit Distance to front end each 60 mm SL: lateral exit left ATTENTION Axial cable exits (ST1/ST2) must be laid free of tension. A tensile load of max. 50 N apply to cables through cable screw connection. SR: lateral exit right Axial exit without PG-screw connection In the case of several sensors connected in sequence, we recommend version S2, SR2 or ST2. These versions provide an additional line in the rubber profile for feedback to the control. Subject to technical modifications 6 Normally...

Cable connection ATTENTION It must be ensured that the lines to the downstream control are double insulated • Cable: Ø 3.3 mm PVC, 1× 0.5 mm2; double insulated, short-circuitproof, highly flexible • Cable length: 1.5 m Option: up to max. 200 m • Cable ends: wires stripped Option: Cable ends available with plug and coupling Connection examples Connection example 1 Normally Closed Safety Edge in series with Emergency-Stop button on Emergency-Stop Control Unit. Connecting voltage: DC. Connection example 2 Normally Closed Safety Edge directly connected to control up to PL e as per ISO 13849-1....

Physical resistance Degree of protection (IEC 60529) Hardness per Shore A Chemical resistance The Safety Edge is resistant to normal chemical influences such as diluted acids and alkalis as well as alcohol over an exposure period of 24 hrs. The values in the table are results of tests carried out in our laboratory to the best of our knowledge and belief. The suitability of our products for your special area of application must always be verified with your own practical tests.

Fixing rails Normally closed Safety Edges SL/NC II are mounted directly to the dangerous main and secondary closing edges. The C26 and C 36 ranges of aluminium profiles are used for mounting. The aluminium profiles are mounted with M5 screws or rivets. Material properties • AlMgSi0.5 F22 • Wall thickness 2 mm • Tolerances as per EN 755-9 Two-part profile for GP 48: For convenient assembly and disassembly. The rubber profile is clipped into the upper section and the upper section inserted in the installed lower section and fastened. Subject to technical modifications Normally Closed Safety...

Standard profile for GP 48: The aluminium profile must first be installed on the closing edge and the rubber profile can than be clipped into the aluminium profile. Two-part profile for GP 65 and GP 100: For convenient assembly and disassembly. The rubber profile is clipped into the upper section and the upper section inserted in the installed lower section and fastened. Subject to technical modifications 12 Normally Closed Safety Edges
