JB-PSE Pressure-Sensitive Safety Contact Edge
The documented tier of contact protection — built for AGV bumpers and powered doors where the risk assessment wants numbers: 13 ms response, defined overtravel, and catalog functional-safety data with DQSRN-SR controllers.
- 13 ms response; actuating travel from <2 mm
- Overtravel up to <45 mm absorbs braking distance
- Catalog FS data: PFH 6.99×10⁻¹⁰/h (ref. SIL 3), Cat. 3
- 7 profiles on 15/25/35 mm rails; angles up to 90°
- IP65, >3,000,000 operations, 30-300 cm to order
When the Edge Has to Appear in the Calculation
A contact edge on an AGV bumper or a powered door is not an accessory — it is a safety function, and modern assessments ask for its numbers. The JB-PSE answers with catalog data most economy edges simply do not publish: PFH 6.99×10⁻¹⁰ per hour (referenced against IEC 61508 SIL 3), Category 3 architecture per EN ISO 13849-1, MTTFd greater than 30 years and B10d of 3×10⁷ — figures stated for the edge operating with a DQSRN-SR / DQSRN-SRA safety controller, alongside design references to EN 1760-1, EN 62061, EN ISO 13849-1 and EN 60204-1.
Mechanically it is tuned for moving equipment. The stop signal fires within 13 ms after as little as 2 mm of compression, and the profile then keeps yielding — up to almost 45 mm of overtravel on the largest section — soaking up the braking distance of the vehicle or door leaf. An actuating angle up to 90° catches glancing hits on chassis corners, and the conformable body follows curves in one made-to-order piece from 30 to 300 cm.
Where documented figures are not required and profile variety matters more, the economy JB series (37 cross-sections) is the better-value pick; for floor-area coverage use the JT14 safety mat, and for non-contact zones ahead of the vehicle, an AGV safety laser scanner.

Typical Applications
AGV / AMR Bumpers
108/110 for compact vehicles, 345/360 for heavy tuggers — conformable around chassis corners.
Powered Doors & Gates
13 ms response and small actuating travel suit fast door leaves; profiles scale with door mass.
Heavy Industrial Doors
345/360 combine higher trip force with up to <45 mm overtravel for long braking runs.
Moving Tables & Lift Platforms
Guards crushing and shearing lines on machine parts where light curtains cannot reach.
Outdoor Installations

Frequently Asked Questions
What makes the JB-PSE different from the economy JB edge on the same site?
Documentation and dynamics. The JB-PSE publishes the figures a machine risk assessment consumes — PFH 6.99×10⁻¹⁰/h referenced against IEC 61508 SIL 3, Category 3 architecture per EN ISO 13849-1, MTTFd over 30 years, B10d of 3×10⁷ — stated for operation with a DQRSN-SR(A) safety controller, plus a defined 13 ms response and per-profile overtravel. The economy JB line offers far more cross-sections (37) but none of those performance figures. If the edge appears in your SISTEMA calculation, it should be a JB-PSE.
Why does overtravel matter so much on an AGV bumper?
Because the vehicle cannot stop in zero distance. The stop signal fires after less than 2-5 mm of compression, but the AGV still needs its braking distance — during which the bumper keeps compressing. The JB-PSE-360 absorbs up to just under 45 mm of overtravel after the switch point, cushioning the person or obstacle while the drives brake. Match profile overtravel to your vehicle's worst-case braking distance at maximum load and speed.
Which profile fits which job?
JB-PSE-108 and 110 (travel <2 mm, 15 mm C-rail on the 110) suit compact AGVs/AMRs and garage-style doors. JB-PSE-215/230/245 (<3 mm travel, 25 mm CS/C/CL rail) are the general-purpose tier for standard AGVs and powered industrial doors. JB-PSE-345/360 (<5 mm travel, up to <45 mm overtravel, 35 mm C/CL rail) handle large AGV bumpers and heavy door leaves with long braking distances. Actuating force runs from about 25 N up to 250 N with profile size.
Does the edge only respond to straight-on impacts?
No — the actuating angle extends up to 90°, so glancing and oblique contacts also trip the edge. That matters on AGV corners and on doors where a hand or shoulder meets the edge at an angle rather than head-on. The profiles are also conformable, following rounded chassis corners and curved door edges in one piece from 30 to 300 cm.
How is the JB-PSE wired into a safety circuit?
Two ways: the R-type 2-wire version carries an integrated terminating resistor (1.2 kΩ or 8.2 kΩ) so a monitoring safety controller supervises the loop for shorts and breaks — this is the configuration behind the published functional-safety figures, stated with DQRSN-SR / DQRSN-SRA controllers, and it supports the EN 1760-1 reset command. The K-type (2- or 4-wire, no resistor) serves controllers without line monitoring. Standard cable is a TPE-sheathed 2×0.35 mm², 2 m long.
Can it live outdoors on a yard gate or dock door?
The edge is rated IP65 with an operating range of -20 °C to +55 °C and humidity to 95 %, which covers sheltered outdoor door and gate installations. Sheath material is EPDM on the 215-360 profiles and TPE on the compact 108/110; oil-resistant and acid/alkali-resistant compounds are available on request for washdown or chemical areas.
What are the certification and safety-claim boundaries I should quote correctly?
The PFH/Category/MTTFd/B10d values are catalog-published functional-safety technical reference data, stated for the edge operating with a DQRSN-SR(A) controller; certification documents are available on request. Category 3 per EN ISO 13849-1 is not a Category 4/PL e claim, and pairing the edge with a higher-rated relay does not upgrade the edge's own architecture — the achieved level always belongs to the complete safety function.
How do I specify a first order for an AGV or door project?
Per position: profile number, length (30-300 cm), R-type resistor value (1.2 or 8.2 kΩ per your controller) or K-type, rail type per the profile's 15/25/35 mm options, and sheath compound if oil/chemical resistance is needed. Mention the mating controller — DQSRN-SR(A) keeps the published data applicable. Small trial quantities are generally workable; contact the factory for current MOQ, pricing and lead time.
