Standard Reflex Lichtschranke und Reflextaster

Standard Reflex Lichtschranke und Reflextaster

Characteristics

standard and small design with same mounting holes

the housings are identically constructed as the safety light barriers

lens front or side mounted

current supply with 10,5 - 30 V DC

insensitiv to impulse light, also of neighbouring light barriers

EMC noise immunity according industry level 3

large optical function angle, simple adjustment

NPN- or PNP-Output

with green switching position LED

Output signals short circuit proof and protected against mix-up

Outputs connectable to our power supply units or directly to machine control (SPS)

also available with: plug M12x1 instead of cable output. Type no. with additional C (e.g. WS 11C)

permissible ambient temperature 0... 50 °C

Supply by receiver

terminals protected against short circuits and changes

housing: ABS, colour black, sealing IP 65

3 m cable (max. 10 m) 3 x 0.25 mm², stripped ends with multicore cable ends

also available with: plug M12x1 instead of cable output. Type no. with additional C (e.g. WE 10C).

max. working frequency 200 Hz

current consumption: WE 10, WE 11, WE 12, WE 13: max. 23 mA
WE 101, WE 121: max. 30 mA

WE 121 P, WE 121	side	standard	12 mm	10 m

Reflex-light barriers

WR 10, WR 10 P, WR 12, WR 12 P, WR 101, WR 101 P, WR121, WR 121 P
The types WR 10 and WR 101 have the lens in front, the types WR 12 and WR 121 have the lens ind side position. Types with the auxiliary letter P have a PNP-output.

3 m cable (max. 10 m) 3 x 0.25 mm², stripped ends with multicore cable ends

current consumption: WR 10, WR 12: max. 23 mA (P-Types 33 mA)
WR 101, WR 121: max. 30 mA (P-Types 40 mA)

Photo transistor viewing angle ± 2,5°

further data identical to standard receivers

	range
reflektor type	WR 10 - WR 12 P	WR 101 - WR 121 P
R 22	0,6 m	0,2 - 1,2 m
R 40	1,4 m	0,2 - 2,8 m
R 80	2,5 m	0,2 - 5 m

photoelectric proximity switches

WV 10, WV 10 P, WV 12, WV 12 P, WV 101, WV 101 P, WV121, WV 121 P
WV 10 and WV 101 have a front mounted lens, the types WV 12 and WV 121 have a side mounted lens. Types with the auxiliary letter P have a PNP-output.
The types WV 101, WV 101 P, WV 121, WV 121 P have no potentiometer for adjustment.

range 10...100 mm with light material, 10...50 mm with dark material

particularly exact scanning in the distance of 35...45 mm

For the improvement of background sensitivity the transmitter is V-shaped with 10° inclination against the optical-axis.

3 m cable (max. 10 m) 3 x 0.25 mm², stripped ends with multicore cable ends

current consumption: max. 30 mA (P-Types 40 mA)

further data identical to standard receivers
