GL-VM96HN 96-Beam 1920 mm Safety Light Curtain Set

The Keyence GL-VM96HN is a Transmitter + Receiver set for industrial control and automation applications.

Keyence GL-VM96HN is a Type 4 safety light curtain transmitter and receiver set with 96 beam axes and a 1900 mm detection height. It provides hand protection with a ø25 mm minimum detectable object size and operates from 24 VDC.

What defines the GL-VM96HN safety light curtain?

This unit pairs optical synchronization with an infrared LED light source at 850 nm. Because synchronization is optical, no separate sync line is required between transmitter and receiver. The effective angular aperture reaches up to ±2.5° at 3 m or above, which supports alignment across the 0.3 to 15 m detecting distance.

Detection mode is ON when all beam axes are received. Interference prevention allows up to 2 units by series connection and switch setting. The response time for the OSSD channel 0, ON→OFF, is max. 7.8 ms.

Electrical specifications and isolation

The supply voltage is 24 VDC -20/+25%, with ripple (P-P) 10% or less, Class 2. Maximum load current is 150 mA or less. Control output is transistor output x2 (NPN). Current consumption with indicator ON is max. 181 mA for the transmitter and max. 196 mA for the receiver, excluding OSSD output current.

Residual voltage (ON) is up to 2.5 V at 5 m cable; OFF voltage is up to 2.0 V at 5 m cable. Leakage current is up to 0.8 mA, maximum load capacity is 0.8 µF, and load wiring resistance is up to 2.5 Ω. Inputs have a short-circuit current of approx. 3 mA. Protection circuits cover supply reverse-connection, per-output short-circuit, and surge.

Safety standards and environmental ratings

Safety standards include IEC61496-1/-2 (Type 4 ESPE/AOPD), EN ISO13849-1 (Category 4, PL e), IEC61508 (SIL3), UL60947-1 / CSA C22.2 No.60947-1, and UL1998. EMC compliance covers IEC/EN61496-1, EN55011 Class A, FCC Part15B Class A, and ICES-003 Class A.

The operating temperature range is -30 to +55 °C (no freezing), and storage temperature is -30 to +70 °C (no freezing). Relative humidity is up to 95 % RH (no condensation). Ambient light tolerance is 3,000 lux or less for incandescent lamp and 20,000 lux or less for sunlight. Protection rating is IP65/IP67 (IEC60529). Vibration resistance is 5 to 150 Hz, 1G, 10 cycles each in X/Y/Z; shock resistance is 15 G, 6 ms pulses, 100 times each in X/Y/Z.

Physical construction and weight

The main unit is aluminum alloy; upper and lower cases are PPS (GF40%); the front cover is polycarbonate and SUS304. Weight is 1250 g for the transmitter and 1260 g for the receiver. Dimensions (H×W×D) are not available in the source data.

How should This unit be integrated?

With no built-in ports, no protocols, and no communication expansion, This unit operates as a standalone safety device. Wiring into a fieldbus network may require an external gateway or connection module; confirm cables and gateways with AutoDCSTech.
