Overview
The LE-P Series is the side-slim type: a 10 × 22 mm section that mounts along the side of a machine frame to guard edges, side entries and narrow access points.It runs 4–292 beams with 70–2994 mm protective heights and 10/20/40 mm beam pitch. Detection distance is 0.01–3 m or 0.01–6 m. Supply 10–30 VDC, NPN or PNP output, optical or line synchronization, response time ≤10 ms, IP65 standard with IP67 optional.
Application scenarios
Conveyor side access
Stops the line when someone reaches over the conveyor side rail.
Gaps between machines
Guards narrow slots where a front or rear curtain will not fit.
Tooling change openings
Detects access during a tool change on a machining centre.
Automated doors and flaps
Monitors the plane of a powered guard before it closes.

Dimensions
| Item | Value |
|---|---|
| Beam pitch | 10 / 20 / 40 mm |
| Effective height | beam count × pitch − pitch |
| Dead bands | 10 mm pitch 22 / 15 · 20 mm 27 / 20 · 40 mm 22 / 30 mm |
| Mounting | Side-mount along a 10 mm frame edge; M12 connector |
The 10 mm dimension is the frame edge it sits on, not the sensing depth — the curtain projects only 22 mm into the machine, which is why it guards side slots a front curtain cannot reach.

How to specify
- 01
Pick the detection capability
Finger protection is Φ15 mm with a 10 mm beam pitch; hand protection Φ25 mm at 20 mm; arm and body detection Φ35 mm at 30 mm; whole-body detection Φ45 mm at 40 mm. The finer the pitch, the closer the operator may stand to the hazard.
- 02
Check how far the hazard is
Where the operator cannot reach the danger zone before the curtain responds, a coarser pitch is acceptable. Where the reach-over distance is short, step down one pitch class — this is the single decision that most often changes the model.
- 03
Choose the profile
30 × 30 mm general-purpose, 35 × 40 mm long range, 32 × 20 mm front slim, 25 × 12 mm front ultra-slim, 10 × 22 mm side ultra-slim, 28 × 28 mm no-blind-zone. The profile is set by the space around the opening, not by the electrical specification.
- 04
Set the protective height
Beam count N and pitch define the effective height: B = N × pitch − pitch. Overall housing length A = B + D + E, where D and E are the lower and upper dead zones including the end caps. Choose the next size up rather than leaving part of the opening unguarded.
- 05
Choose output, sync and connection
NPN or PNP, normally-open or normally-closed, in four combinations. Optical synchronisation needs no link wire (5-wire); line synchronisation is immune to cross-talk between adjacent curtains (7-wire). Cable gland or M12 connector at order.
- 06
Confirm the working distance
Standard series align over 0.1–8 m; the long-range series reaches 25–30 m. Check the emitter/receiver pairing table before ordering a mixed set — not every series can be cross-paired.
Why this series
10 mm wide
The thinnest section in the range, made for side mounting where only a few millimetres of frame are available.
Side-facing optics
The optical axis sits along the 22 mm face, so the curtain can guard an edge or a side entry without a frame redesign.
Same beam performance
4–292 beams, 10/20/40 mm pitch and ≤10 ms response, like the rest of the range.
Questions
Why does the LE-P start at 0.01 m?
The side-slim optics are specified for 0.01–3 m and 0.01–6 m detection distances — a close-to-mid-range curtain for guarding the immediate edge of a machine.
Can I mix LE-P and LE-F on one machine?
Yes. Both are slim curtains with the same beam counts, pitch options and electrical interface; the choice is driven by mounting space and the distance between emitter and receiver.
Which output is available?
NPN or PNP transistor output. For relay contacts choose the LE-B or LE-C series.
