CONEC wins UL approval per UL2238, File E318363
CONEC has received a UL listing based on the UL standard 2238 for special components (overmoulded connectors and sockets) in its M12x1 series.
The following articles are now listed per UL2238.
1. M12x1 – Overmoulded round connectors in styles:
â€¢ Female/male connector, axial and angled
â€¢ Female connector, angled, with 2 or 3 LEDs
â€¢ Female/male connector, axial with 360Â° shielding
â€¢ Connecting cables made up with the aforementioned components.
Cable lengths which deviate from standard lengths are also UL2238 certified.
â€¢ 3 to 8 poles
â€¢ K1 = TPU, UL, highly flexible, halogen-free
â€¢ G2 = TPU, UL, highly flexible, halogen-free, shielded
2. M12x1 – sockets in styles:
â€¢ Female/male socket with PG9 or M16x1.5 threads
â€¢ front mounting, back mounting versions, each available with wires or PC contacts
â€¢ 4, 5 and 8 poles
General information about UL2238 test procedures:
UL2238, with its more stringent test methods, has replaced its predecessor, UL1977. UL2238 places greater demands on the materials used. A highlight here is the flammability classification per UL94, required of any plastic materials used, and the subsequently derived values for:
RTI = Relative Temperature Index (continuous use temperature)
HWI = Hot Wire Ignition (contact overheating is simulated)
HHI = High Current Arc Ignition (plastic is exposed to high-current arcing)
Plastic materials typically do not achieve the values required by the standard under a wall thickness of about 1.6 to 3.0 mm. Wall thicknesses in the contact area of M12x1 connectors are considerably less. The consequence of this is that
UL certification is only possible with a reduction of the specification for rated voltage.
Rated voltage for a 4-pos connector to date: 250 V
Rated voltage for these articles per UL2238 is now: 30 V
