Economy M4/M5/M6 Inductive Proximity Switch
The smallest, lowest-cost tier of the DAIDISIKE inductive range — for fixtures and jigs where an M8 barrel simply does not fit and every yuan per point counts.
- ⌀4 mm smooth-barrel M4, threaded M5×0.5 and M6×0.75
- Body lengths 25 / 30 / 35 mm — incl. short E2E4/E2E5 versions
- 1.0 mm ±10% sensing distance on standard bodies
- NPN or PNP, NO or NC (suffix-coded, easy to cross-reference)
- Brass body; M5/M6 standard versions flush-mountable
Economy vs Standard vs High-Grade Miniature Sensors
DAIDISIKE offers three miniature tiers, and choosing between them is mostly a budget-versus-options decision. The M3/M4 ultra-small and M5/M6 standard pages cover the regular lines; the high-grade threaded M4–M6 series adds multiple sensing-distance grades from 0.6 to 1.5 mm with a published wiring diagram. This economy line is the entry point: a single 1.0 mm grade, brass construction, and the 25 mm E2E4/E2E5 short bodies as the absolute lowest-cost option — aimed at OEMs fitting many identical detection points per machine.
The trade-off is documentation depth: voltage range, IP rating and response time are not published for this line (the factory confirms them per order), whereas the higher tiers publish fuller specs. If your specification sheet demands documented figures, start one tier up.

"Contact factory" entries are deliberately left open: those values are not published for this economy line and we would rather you confirm than guess. Operating voltage for the whole line should also be confirmed at order time.
Short-Body Export Versions (25 mm)
Typical Applications
Tight fixture pockets
⌀4 mm barrel drops into jigs and tooling where even an M8 sensor cannot physically mount.
Cylinder end-of-stroke
Compact confirmation of actuator position beside small pneumatic cylinders.
Small-part presence
1.0 mm close-range detection of screws, pins and stamped parts in feeders and nests.
High-volume OEM builds
25 mm E2E4/E2E5 short bodies keep per-point cost down across dozens of identical stations.
Frequently Asked Questions
How does this economy M4/M5/M6 line differ from the standard DAIDISIKE M5/M6 and M3/M4 pages?
Three tiers exist in the miniature range. The standard M5/M6 and ultra-small M3/M4 series on this site are the regular product lines; the high-grade threaded M4–M6 series adds multiple sensing-distance grades (0.6–1.5 mm); and this economy line is the entry price point — one 1.0 mm sensing grade, brass body, with extra-short 25 mm E2E4/E2E5 versions for the tightest budgets. Same miniature footprint, simpler option list, lower cost per point.
What does the model suffix ZB / ZA / X / Y mean?
ZB = NPN output, ZA = PNP output; X = normally open (NO), Y = normally closed (NC). Example: JJ5A3-1-ZAX is the M5, PNP, normally-open version. Note the short E2E4/E2E5 bodies are catalogued in NO form only — NC availability should be confirmed with the factory.
What is the confirmed sensing distance?
The 30 mm M4, 30 mm M5 and 35 mm M6 versions are all rated 1.0 mm ±10% on the factory selection chart. The shorter 25 mm E2E4/E2E5 bodies have no published figure — treat their distance as to-be-confirmed with the factory rather than assuming 1.0 mm.
Can these be mounted flush in metal?
The M5 (30 mm) and M6 (35 mm) versions are marked flush/shielded on the factory chart, so they can sit level with surrounding metal. Flush behaviour of the M4 and the short E2E4/E2E5 bodies is not documented — leave clearance or ask the factory before embedding them.
What supply voltage do they need?
The wiring is 3-wire DC, but a voltage range is not published for this specific economy line. Confirm the operating voltage with the factory when ordering — do not assume it matches other DAIDISIKE lines. If a documented 10–30 V DC rating matters to your design, the high-grade or standard miniature series are the safer choice.
Are these safety-rated for guard door interlocks?
No. They are plain presence/position sensors with no IEC 61496 / ISO 13849 certification, so they must not be used alone for personnel protection. They can feed a door open/closed status signal to a controller, but guarding duty needs a certified safety switch or light curtain.
How do I get pricing, samples and lead time for an OEM volume?
Quote requests go through the contact page — list the model codes (e.g. JJ6A3-1-ZBX × 500) and target cable length. The short E2E4/E2E5 bodies are the lowest-cost option and are usually the right pick for high-volume builds where the extra 5 mm of body and NC output are not needed.
