SEN/H/R3 – Sentry 3 Channel Receiver Code Hopping

The Sentry SEN/H/R3 is a secure 3-channel code hopping receiver designed for professional access control and automation applications where robust, reliable performance is critical. Operating at 433.92 MHz, this receiver is factory-coded with over 260 million unique combinations (66-bit encryption) for exceptional protection against code grabbing and cloning.

Compatible with Sentry 1, 3, and 4-channel transmitters, each SEN/H/R3 receiver can store up to 8 unique transmitters. For larger installations supporting up to 1,000 users, consider the Sentry SEN/H1000/R1 receiver.

This surface-mounted unit features selectable latch or pulse output modes and normally open/normally closed contacts for flexible integration with gates, barriers, and other automation equipment. SAW resonator stabilisation ensures reliable performance, while high sensitivity (≥110 dBm) guarantees strong signal reception.

The SEN/H/R3 provides potential-free relay outputs with a 3A maximum switching capacity per channel (10mA for 1CH), operating on a 12–24V AC/DC external power supply.
